Two new species of the millipede genus Anamastigona are described, A. cypria sp. nov. and A. strasseri sp. nov., both from the island of Cyprus. The new species are considered to be most similar to A. terraesanctae Golovatch & Makarov, 2011 from Israel, the three of them forming a species group which is briefly characterized. An updated key to all 20 recognized species of the genus Anamastigona is provided and a short overview of the taxonomy of the genus is given.

Four new species of the genus Coecobrya, C. gejianbangi sp. nov., C. annulata sp. nov., C. ciliata sp. nov., and C. oculata sp. nov., are described from Guangxi caves as the representative of the genus in China. Coecobrya oculata sp. nov. of the boneti-group has 1+1 eyes and a serrate outer edge of the unguiculus. The other three species, devoid of eyes and with a tiny outer tooth on the unguiculus, are assigned here to the tenebricosa-group, assuming that the large tooth on the unguiculus is transformed into a tiny one in cave-obligate species. Clypeal chaetae in Entomobryoidea are systematically surveyed for the first time, and are found to be well diversified at species level. They have a potential taxonomical value in discriminating taxa of morphologically conserved groups.

We revise the Southeast Asian Pholcus bicornutus group in which males are characterized by a unique pair of horns on their ocular area, each of which carries at its tip a brush of hairs. In two species, the two hair brushes are ‘glued’ or ‘waxed’ together by an unidentified substance into a very consistently curved and pointed single median tip. In the other five species known, the hairs are unglued. We present a first revision of ocular modifications in Pholcidae and identify twenty supposedly independent origins. Most cases are in Pholcinae, and all but one case are limited to the male, suggesting sexual selection as the main driving force in the evolution of ocular modifications in Pholcidae. Previously, the Pholcus bicornutus group consisted of four species limited to the Philippines. We describe four new species, including three species from the Philippines (P. olangapo Huber, sp. nov.; P. kawit Huber, sp. nov.; P. baguio Huber, sp. nov.) and the first representative from outside the Philippines (P. mulu Huber, sp. nov. from Sarawak, NE Borneo) and provide new records and SEM data for three previously described species.
224
A new species of laevicaudatan branchiopod, Lynceus insularis sp. nov., is described. It is reported from five sinkholes (dolines) in the southern part of New Caledonia. Lynceus insularis sp. nov. is closest to Lynceus species from Australia, but can be separated from these on the basis of clasper morphology and the form of the lamina abdominalis. Lynceus insularis sp. nov. is the first record of a remote insular endemic laevicaudatan. The habitats of the species may be threatened due to hydrological changes, reduction of water supply, acidification of fresh water, invasive species, and/or mining activities in the vicinity.
223
By taking Flavalona gen. nov. out of Alona s.l. (Cladocera: Anomopoda: Chydoridae), the last major clade has now been removed from this polyphyletic assemblage. Flavalona gen. nov. is a monophylum defined by having three, rarely two connected head pores and slit-shaped, rarely rounded lateral head pores. Postabdomen rather long, distally narrowed, with robust marginal denticles and weakly developed lateral fascicles of setules. End-claw weakly curved and with short basal spine. Male postabdomen with gonopores opening at the end of a penis-like outgrowth. Trunk limbs: exopodite of P2 with seta; inner portion of P4 with flaming-torch shaped setae; P5 with filter plate of three setae; P6 a large simple lobe. The relationship of the new genus with other Aloninae remains to be determined. A key to the 11 species of the genus is provided and a discussion of their geographic distribution and habitat type is given.
222
Harpactea dufouri (Thorell, 1873) was collected in the Gavarres protected natural area in Catalonia, Spain. The specimens were compared with specimens from Mallorca, Balearic Islands,
and found to be conspecific. The female of the species is described here for the first time. The new finding proves that Harpactea dufouri occurs outside the Balearic Islands. The species, however, may be endemic to Catalonia.
221
Three new genera of Odontopygidae are described, all based on new species from the Udzungwa mountains, Tanzania, and all monotypic: Casuariverpa gen. nov. (type species: C. scarpa gen. et sp. nov.), Yia gen. nov. (type species: Y. geminispina gen. et sp. nov.), and Utiliverpa gen. nov. (type species: U. decapsulatrix gen. et sp. nov.). Similarities and differences between the new genera and other genera are discussed.
220
Knowledge about the taxonomy and distribution of the monogeneric polychaete family Longosomatidae Hartman, 1944 is limited in all parts of the world. A new species of the genus Heterospio Ehlers, 1874 (Annelida, Longosomatidae) is described from the Indian Ocean. Heterospio indica sp. nov. is mainly characterised by the conspicuous flattening of the distal half of capillary chaetae located in anterior elongated segments. Several body characters of high taxonomic relevance in the genus are examined under the SEM and discussed. The 18S SSU rDNA and COI genes were sequenced and represent the first sequencing of a species of Heterospio, and the sequences have been deposited in GenBank.
219
We identified a high diversity in the net-winged beetles of the genus Cautires in Peninsular Malaysia. Fourteen new species are described: Cautires alexae sp. nov., C. andujari sp. nov., C. arribasae sp. nov., C. berembanensis sp. nov., C. campestris sp. nov., C. communis sp. nov., C. jasarensis sp. nov., C. katarinae sp. nov., C. kirstenae sp. nov., C. kotatinggensis sp. nov., C. linardi sp. nov., C. maseki sp. nov., C. pahangensis sp. nov. and C. renatae sp. nov. Seven previously described species are discussed, illustrated and differential diagnoses provided; all species are keyed. The Cautires species differ in a limited number of diagnostic characters, namely in the shape of male antennae, the relative size of eyes and in the shape of the male genitalia. The females are difficult to assign to a conspecific male due to high intraspecific variability. The characteristically low dispersal propensity of net-winged beetles lead to the evolution of the unique fauna in the Malay mountains and despite an extensive study of the type material we recorded only a single species of Cautires occurring simultaneously in Sumatra. We suggest that the Malay mountain fauna is highly endemic and evolved in situ.

Forty-three species of sertulariid hydroids (Cnidaria: Hydrozoa: Sertulariidae), collected from the tropical western Pacific (Taiwan, Philippines, New Caledonia, French Polynesia, Vanuatu, Fiji, Tonga, Solomon Islands) during various expeditions of the French Tropical Deep-Sea Benthos program, are discussed. Of these, nine are new to science: Gonaxia nova sp. nov., G. plumularioides sp. nov., Sertularella folliformis sp. nov., Se. plicata sp. nov., Se. pseudocatena sp. nov., Se. splendida sp. nov., Se. tronconica sp. nov., Se. tubulosa sp. nov., and Symplectoscyphus paucicatillus sp. nov. The subspecies Symplectoscyphus johnstoni (Gray, 1843) tropicus Vervoort, 1993 is raised to species but, in order to avoid the secondary homonymy with Sy. tropicus (Hartlaub, 1901), the replacement name, Sy. fasciculatus nom. nov., is introduced. The male and female gonothecae of Diphasia cristata Billard, 1920, the male gonothecae of Gonaxia elegans Vervoort, 1993, as well as the female gonothecae of Salacia macer Vervoort & Watson, 2003, are described for the first time. Additional notes on the morphology of several other species are provided. All taxa are illustrated, in most cases using figures drawn at the same scale, so as to highlight the differences between related species.
217
Four monoraphid taxa belonging to the genera Achnanthes, Psammothidium and Planothidium were found during the ongoing taxonomic revision of the freshwater and limno-terrestrial diatoms of the Maritime Antarctic region. The present paper describes these four taxa as new based on detailed light and scanning electron microscopy observations: Achnanthes kohleriana Kopalová, Zidarova & Van de Vijver sp. nov., Planothidium wetzelectorianum Kopalová, Zidarova & Van de Vijver sp. nov., Psammothidium confusoneglectum Kopalová, Zidarova & Van de Vijver sp. nov. and Psammothidium superpapilio Kopalová, Zidarova & Van de Vijver sp. nov. The morphology and ecology of all four taxa are discussed and the species are compared with morphologically similar taxa.
216
Within the central European opilionid fauna the widely used species names Leiobunum rupestre Herbst, 1799 and Leiobunum tisciae Avram, 1968 pose taxonomic and distributional problems. In addition, Nelima apenninica Martens, 1969 is close to L. tisciae in terms of external and genital morphology, but is specifically distinct. While coxal denticulation is largely lacking in N. apenninica, the validity of the genus Nelima Roewer, 1910 is questioned again. In addition, Leiobunum subalpinum Komposch, 1998, a recently described novelty from the eastern Alps, is closely related to L. rupestre. The four species are combined as the morphologically defined Leiobunum rupestre species group. Except for L. subalpinum, they were found to be allopatrically distributed from the Carpathians across central and Northwest Europe to the south-western Alps. The latter species is locally sympatric and partly elevationally parapatric to L. rupestre. Leiobunum tisciae is a recently introduced name and here recognized as a junior synonym of a number of taxa described much earlier, of which L. gracile Thorell, 1876 is re-introduced as oldest available name. Detailed morphological and distributional data for all taxa are presented.
215
Two species of the genus Prionopetalum Attems, 1909, are recorded from the Udzungwa Mountains: P. asperginis sp. nov. and P. kraepelini (Attems, 1896). Prionopetalum stuhlmanni Attems, 1914, is synonymized under P. kraepelini. Odontopyge fasciata Attems, 1896, is transferred from Prionopetalum to Aquattuor Frederiksen, 2013, and new illustrations are given. A new illustrated key to species of Prionopetalum is provided.
214
The spider genus Zaitunia Lehtinen, 1967 (Araneae, Filistatidae) is revised. It was found to include 24 species distributed in the Eastern Mediterranean, Middle East and Central Asia: ♀ Z. afghana (Roewer, 1962) (Afghanistan), ♀ Z. alexandri Brignoli, 1982 (Iran), ♀ Z. akhanii Marusik & Zamani, 2015 (Iran), ♂♀ Z. annulipes (Kulczyński, 1908) (Cyprus), ♂♀ Z. beshkentica (Andreeva & Tyshchenko, 1969) (Tajikistan, Uzbekistan), ♀ Z. brignoliana sp. nov. (Iran), ♂♀ Z. ferghanensis sp. nov. (Kyrgyzstan, Uzbekistan), ♀ Z. feti sp. nov. (Turkmenistan), ♀ Z. halepensis sp. nov. (Syria), ♀ Z. huberi sp. nov. (Afghanistan), ♀ Z. inderensis Ponomarev, 2005 (Kazakhstan), ♂♀ Z. kunti sp. nov. (Cyprus, Turkey), ♂♀ Z. logunovi sp. nov. (Kazakhstan, Kyrgyzstan), ♂♀ Z. maracandica (Charitonov, 1946) (Uzbekistan, Kazakhstan), ♂♀ Z. martynovae (Andreeva & Tyshchenko, 1969) (Tajikistan, Turkmenistan), ♀ Z. medica Brignoli, 1982 (Iran), ♂♀ Z. minoica sp. nov. (Greece), ♀ Z. minuta sp. nov. (Uzbekistan), ♀ Z. persica Brignoli, 1982 (Iran), ♂ Z. psammodroma sp. nov. (Turkmenistan), ♂♀ Z. schmitzi (Kulczyński, 1911), the type species (Egypt, Israel), ♂♀ Z. spinimana sp. nov. (Kazakhstan, Turkmenistan), ♂♀ Z. wunderlichi sp. nov. (Kyrgyzstan) and ♀ Z. zonsteini Fomichev & Marusik, 1969 (Kazakhstan). Twelve above-listed species are newly described, and males of Z. annulipes, Z. beshkentica, Z. maracandica and Z. martynovae are described for the first time. Two new combinations are established: Z. annulipes (Kulczyński, 1908) comb. nov., ex Filistata, and Pholcoides monticola (Spassky, 1941) comb. nov., ex Zaitunia. New data on distribution of the considered taxa are provided.

An alphabetical list of 352 type lots of molluscs housed in the Museu de Zoologia da Universidade de São Paulo is presented following the standards of the previous list by Dornellas & Simone (2011), with a few adjustments. Important items listed herein include types of species described after the previous compilation, as well as recently acquired paratypes of Asian Pomatiopsidae and Diplommatinidae (Gastropoda) taxa described by Rolf A.M. Brandt (1960s), P. Temcharoen (1970s) and W.J.M. Maassen (2000s), all of which belonged to the private collection of Jens Hemmen, Wiesbaden, Germany. Relevant items also include types of recently described species coming from the French- Brazilian Marion Dufresne MD55 expedition, and other types deposited by researchers from Brazil and the world. A list of authors and photographs of specimens are also provided.
212
The studies of Cyclops O.F. Müller, 1776 have more than two centuries of tradition in Fenno- Scandinavia, yet, basic taxonomic questions remain unresolved and the limits of the distributional area are very poorly understood in the majority of the taxa (11+) occurring in the region. Based on the types and other materials we redescribe two species, C. lacustris G.O. Sars, 1863 and C. bohater Koźmiński, 1933, the latter being reported here for the first time from Fenno-Scandinavia; lectotypes of both species have been designated herein. Setulation characters of the antennal coxobasis- and maxillulary palp setae and P1 medial spine, as well as the spine formula of the terminal exopodal segments of the swimming legs (3433) in the adult female distinguish C. lacustris and C. bohater from their congeners. An identification key is provided to the Cyclops species of Fenno-Scandinavia, including information about both the female and male morphology. Although the limited material does not allow us to define the species range limits, our data nevertheless support a Northern European distribution in C. lacustris, and Northern and Central European distribution in C. bohater, while the records from the southern Palearctic need further verification.
211
Bothriomyrmex enigmaticus sp. nov. is described from the island of Hispañola based on one nest collection. This is the first collection of the genus Bothriomyrmex (Emery, 1869) from the Caribbean region, and the second species to be described from the Americas. While sharing several characters with B. paradoxus (Dubovikoff & Longino, 2004) from Costa Rica and Honduras, B. enigmaticus sp. nov. diverges in several key characters, including palp formula. However, a morphometric comparison to Palearctic species of the tribe Bothriomyrmecini suggests affinities to B. paradoxus, Chronoxenus wroughtoni (Forel, 1895) of the eastern Palearctic, and to a lesser extent an undescribed species of Arnoldius (Dubovikoff, 2005) from Australia and B. corsicus (Santschi,1923) of the western Palearctic.

Diplura C.L. Koch, 1850 is a mygalomorph genus with putative records from Central and South America. The type-species Diplura macrura (C.L. Koch, 1841), originally described from West Indies, is poorly known and represented only by its holotype. Most of the 20 species currently included in the genus lack modern taxonomic descriptions, as D. lineata (Lucas, 1857), from Rio de Janeiro state, Brazil. Males and females of Diplura macrura and D. lineata are herein redescribed. New junior synonyms of D. macrura are identified (Linothele bicolor (Simon, 1889), Diplura uniformis Mello- Leitão, 1923, and the two junior synonyms of the latter species, Thalerothele minensis Mello-Leitão, 1926 and T. aurantiaca Mello-Leitão, 1943). Also, two junior synonyms are established for D. lineata: Diplura fasciata (Bertkau, 1880) and Diplura nigridorsi (Mello-Leitão, 1924). The type-locality of D. macrura is corrected to São João del Rei, Minas Gerais state, Brazil. D. macrura is restricted to the state of Minas Gerais and D. lineata to the state of Rio de Janeiro. The type-locality of D. parallela (Mello-Leitão, 1923) is also corrected from Argentina to Paraná state, Brazil. The distribution of Diplura is now restricted from south Panama to north Argentina, excluding previous erroneous records for Cuba and West Indies. The six synonymies herein established help to clarify the genus composition, which includes now 17 valid species.
209
Eight species of the genus Notosemus Förster, 1869 (Hymenoptera: Ichneumonidae) are reported, three of which are new to science: N. albimaculatus Sheng & Sun, sp. nov. and N. planus Sheng & Sun, sp. nov., both collected from Xizang Autonomous Region, SW China, and N. wugongicus Sheng & Sun, sp. nov., collected from Jiangxi Province, S China. One new record for China, N. bohemani (Wesmael, 1855), was reared from Zeiraphera griseana (Hübner, 1789) (Lepidoptera, Tortricidae), a leaf pest of Larix principis-rupprechtii Mayr. (Pinaceae) in Ningxia Hui Autonomous Region, NW China. A key to the species of the genus Notosemus is provided.

Phylogenetic analyses of the highly diverse (non-marine aquatic) gastropod family Hydrobiidae Stimpson, 1865 have revealed seven main lineages, most of which represent subfamilies. The subfamily Pseudamnicolinae Radoman, 1977, and specifically the genus Pseudamnicola Paulucci, 1878 (mainly inhabiting western and central Mediterranean regions), contributes substantially to this hydrobiid richness. Most of its congeners have been described in terms of their shell and penis features, which are of limited diagnostic value. Hence, the taxonomic status of some Pseudamnicola species needs to be revised, particularly of those inhabiting marginal regions, such as the Ponto-Caspian domain, largely occupied by the subfamily Pyrgulinae Brusina, 1882. Here we present a molecular phylogeny including species of both subfamilies along with extended morphological descriptions to confirm assignments of the Iranian species Pseudamnicola zagrosensis Glöer & Pešić, 2009; Sarkia kermanshahensis Glöer & Pešić, 2009 (originally within Pseudamnicola) and P. saboori Glöer & Pešić, 2009. Our COI-based tree rejects these assignments suggesting a new potential lineage, sister to the pyrgulinid species, and comprising three genera: Shadinia Akramowski, 1976, Intermaria gen. nov. and Persipyrgula gen. nov. These genera differ molecularly by 3.6%–8.5%, and are diagnosable by penis, female genitalia and radula features. Our findings evidence the high morphological variability of pyrgulinid species and provide insight into the origins and evolution of the freshwater Ponto-Caspian fauna.
207
A new cheilostome bryozoan genus, Powellitheca gen. nov., is erected here for three species from New Zealand, one of which has been previously assigned to Emballotheca Levinsen, 1909, but which differ significantly from the Australian type species of Emballotheca, E. quadrata (MacGillivray, 1880). Notably, whereas Emballotheca has a cormidial orifice (i.e., formed by numerous neighbouring zooids), and lepralielliform ooecia, the orifice of Powellitheca gen. nov. is formed by single zooids and ooecia are of the microporelliform type. The introduction of a new family, Powellithecidae fam. nov., becomes necessary because of the nonconformity of Powellitheca gen. nov. with other known families having microporelliform ooecia. In addition to the Recent type species Powellitheca terranovae gen. et sp. nov., one other new Recent species, P. labiosa gen. et sp. nov., and a Plio-Pleistocene fossil species, Monoporella waipukurensis Waters, 1887, are assigned to the new genus.
206
The New World Clistopyga chaconi species group is revised. Eleven species are described as new: C. amazonica sp. nov., C. cinnamoptera sp. nov., C. cuscoensis sp. nov., C. hayesiana sp. nov., C. melanoptera sp. nov., C. misionensis sp. nov., C. mocaguae sp. nov., C. orellanae sp. nov., C. porteri sp. nov., C. rondoniae sp. nov. and C. yabuquensis sp. nov. Additional morphological data are provided for the previously known species, C. caramba Castillo & Sääksjärvi and C. chaconi Gauld. An illustrated identification key to all species of the group is provided. The Clistopyga chaconi species group appears to be most diverse at the Andean and Amazonian interface in western South America.
205
A new troglobitic species of the previously monotypic genus Biokoviella Mršić, 1992, B. mosorensis Antić & Dražina sp. nov., is described from caves on Mt. Mosor, Croatia. In addition to this, B. mauriesi Mršić, 1992, is partially re-described, and the taxonomic status of the family Biokoviellidae is re-considered. The genus Biokoviella is placed in the subfamily Biokoviellinae Mršić, 1992 stat. nov. within the family Anthogonidae Ribaut, 1913. The relationship of the genus Biokoviella with other anthogonids is briefly discussed, and a distribution map of the genus is presented. Notes on ecology and coinhabitants of the genus Biokoviella, and new data on some Balkan anthogonids are also included in the paper.
204
F.T. Kützing introduced Cocconeis molesta with only an uninformative description and a poor illustration: C. molesta has small, oblong valves and is an epiphyte. Another species, Cocconeis diaphana, described by William Smith, is said to have larger valves than C. molesta, with frustules that are relatively oblong. Smith described two forms: one with a distinct fascia on its raphe valve (var. β), the other without this feature. A third species, Cocconeis dirupta was described by Gregory, who expressed doubts that it differed from C. diaphana. Finally, Cocconeis molesta var. crucifera Grunow was first introduced in Van Heurck’s Atlas but was subsequently treated by Van Heurck as a synonym of C. molesta. No previous account has examined the type material of these species. In this paper, we undertake that task and examine type slides and raw material in order to discriminate these different taxa. We conclude by recognizing three species: Cocconeis molesta Kütz., C. diaphana W.Sm. and C. dirupta W.Greg. Cocconeis diaphana var. β is considered to be a synonym of C. dirupta and C. molesta var. crucifera is considered to be a synonym of C. molesta. Lectotypes are designated for C. diaphana and C. dirupta.

Diversity and distribution of adeonid bryozoans (Cheilostomata: Adeonidae) in Japanese waters
(2016)
Adeonid bryozoans construct antler-like erect colonies and are common in bryozoan assemblages along the Japanese Pacific coast. The taxonomy of Japanese adeonid species, however, has not been studied since their original descriptions more than 100 years ago. In the present study, adeonid specimens from historical collections and material recently collected along the Japanese coast are examined. Eight adeonid species in two genera were detected, of which Adeonella jahanai sp. nov., Adeonellopsis parvirostrum sp. nov., and Adeonellopsis toyoshioae sp. nov. are described as new species based on the branch width, size and morphology of frontal or suboral avicularia, shape and size of areolar pores, and size of the spiramen. Adeonellopsis arculifera (Canu & Bassler, 1929) is a new record for Japan. Lectotypes for Adeonellopsis japonica (Ortmann, 1890) and Adeonella sparassis (Ortmann, 1890) were selected among Ortmann’s syntypes. Most species of Adeonellopsis around Japan have a southern distribution from Sagami Bay to Okinawa, while A. japonica shows a more northern distribution from Kouchi to Otsuchi. In contrast, Adeonellopsis arculifera was collected only from southwestern Japan. A key to Japanese adeonid species is provided.

A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N. cibyci sp. nov. and N. tepoztlanensis sp. nov., were both found inhabiting bromeliads (Tillandsia spp.) and living on two tree species (Quercus obtusata and Sapium macrocarpum); the third, N. tescalicola sp. nov., was found in soil and litter under Q. obtusata. These three new species can be differentiated from other species in the genus by a combination of morphological characters in adult females, mainly those setae on femora and genua I. The idiosoma and leg setal ontogeny of a camerobiid mite is presented for the first time in this paper, illustrating chaetotaxic notations and their relative positions in N. cibyci sp. nov. larva, protonymph and adults (female and male), and establishing setal homologies among instars. Setal homology with other species in the cohort Raphignathina is briefly discussed. Additionally, a compilation and an identification key to all known species of camerobiid mites in Mexico is provided.
201
Two new species of Tetrastigma from Thailand, T. calcicola Kochaiph. & Trias-Blasi sp. nov. and T. jaichagunii C.L.Li ex Kochaiph. & Trias-Blasi sp. nov. are described and illustrated. Tetrastigma calcicola sp. nov. is a slender climber restricted to the open areas on limestone mountains at high elevation in the northern part of Thailand. The other species, T. jaichagunii sp. nov., is similar to T. harmandii Planch., but differs from it by having more densely verrucose young branches, broader leaflets, 4-lobed thick discs, bigger globose berries and oblongoid seeds. This species occurs along streams or in forest margins in evergreen forest and it is widely distributed in several parts of Thailand.

New leaf- and litter-dwelling species of the genus Pholcus from Southeast Asia (Araneae, Pholcidae)
(2016)
We describe eight new species of the genus Pholcus, and document their microhabitats. Four species are assigned to the previously described Pholcus ethagala group: P. tanahrata Huber sp. nov., P. uludong Huber sp. nov., and P. bukittimah Huber sp. nov. from the Malay Peninsula, and P. barisan Huber sp. nov. from Sumatra. These species are all litter-dwellers that build domed sheet webs on the undersides of large dead leaves on the ground. The other four species are assigned to newly created species groups: the P. tambunan group with two species from northern Borneo: P. tambunan Huber sp. nov. and P. bario Huber sp. nov.; and the P. domingo group with two species from the Philippines, Mindanao: P. domingo Huber sp. nov. and P. matutum Huber sp. nov. These latter four species are leafdwellers that build barely visible silk platforms tightly attached to the undersides of live leaves. The main rationale for this paper is to provide part of the taxonomic and natural history background for upcoming phylogenetic and evolutionary (microhabitat shifts) analyses.

The Thyropygus opinatus subgroup (Diplopoda: Harpagophoridae) of the T. allevatus group in Thailand is revised. Based on a phylogenetic analysis of mtDNA sequence data, it is merged with the T. bifurcus subgroup to form an extended T. opinatus subgroup. Nine new species are described: Thyropygus cimi sp. nov. and T. forceps sp. nov. from Nakhonsrithammarat Province, T. culter sp. nov., T. planispina sp. nov., T. undulatus sp. nov. and T. ursus sp. nov. from Krabi Province, T. mesocristatus sp. nov. from Songkhla Province, T. navychula sp. nov. from Phang-Nga Province and T. sutchariti sp. nov. from Phetchaburi Province.
198
The new subgenus Maculergithus subgen. nov. is established to accommodate two new species of the genus Gergithus Stål, 1870 (Issinae, Hemisphaeriini): G. (Maculergithus) tamdao subgen. et sp. nov. and G. (Maculergithus) luteomaculatus subgen. et sp. nov. from Tam Dao National Park in North Vietnam. Two more species from Hainan, China, G. multipunctatus Che, Zhang & Wang, 2007 and G. nonomaculatus Meng & Wang, 2012 are also placed in Maculergithus subgen. nov. A fifth species from Hainan, yet undescribed and erroneously identified as G. multipunctatus in recent papers also belongs to this new subgenus. Illustrations of habitus, morphological details and male genitalia together with a distribution map and an identification key to the species of Maculergithus subgen. nov. are provided. Four species of the genus Gergithus are now recorded in Vietnam. A rectificative note on the misinterpretation of G. multipunctatus in recent publications on Issidae is also provided.
197
Two new species of the genus Chrysotus Meigen, 1824 are described: Ch. masunagai Negrobov, Kumazawa, Tago sp. nov and Ch. saigusai Negrobov, Kumazawa & Tago sp. nov. Chrysotus parilis Parent, 1926 is recorded from Japan for the first time. An identification key to all known species of the genus Chrysotus of Japan is presented together with a tree diagram showing relationships among them.

Brooksia lacromae sp. nov. is described from zooplankton material collected at a marine monitoring station in the South Adriatic in the autumn of 2014. The description of both solitary and aggregate forms is given along with 18S rRNA and mitochondrial cox1 sequence data that provides strong evidence that both forms belong to the same species. The described species is morphologically markedly different from B. rostrata (Traustedt, 1893) and B. berneri van Soest, 1975, previously the only two species in the genus Brooksia. Genetic analysis based on 18S rRNA gene confirmed distinctness of B. lacromae sp. nov. from B. rostrata (1.5% uncorrected pairwise distance). The appendicularian Fritillaria helenae Bückmann, 1924, so far known from the Atlantic only, was found in the same samples as B. lacromae sp. nov. Co-occurrence of B. lacromae sp. nov. with an Atlantic appendicularian suggests an Atlantic or Western Mediterranean origin for this new taxon.

The Indochinese to southern Chinese millipede genus Tylopus currently comprises 62 species, including eight new ones: T. flavolineatus sp. nov., T. hongkhraiensis sp. nov. from central and northern Thailand, respectively, T. moniliformis sp. nov., T. retusus sp. nov., T. acuminatus sp. nov., T. dorsalis sp. nov., T. thunghaihin sp. nov., all from Laos, and T. punctus sp. nov. from northern Myanmar. A new record of T. baenzigeri Golovatch & Enghoff, 1993, from northern Thailand is given. All these species are richly illustrated, and a modified key to all known species of the genus is also provided.

When based on phylogenetic proposals, biogeographic historic narratives have a great interest for hypothesizing paths of origin of the current biodiversity. Among the many questions that remain unsolved about psocids, the distribution of Thyrsophorini represents still a remarkable enigma. This tribe had been considered as exclusively Neotropical, until the description of Thyrsopsocopsis thorntoni Mockford, 2004, from Vietnam. Three hypotheses have been proposed to explain this atypical distribution, recurring to dispersal, vicariance and morphological parallelism between lineages, but the lack of evidence has not allowed a unique support. Here, we describe a new Neotropical species of Thyrsopsocopsis, and also attempt to test the three biogeographical hypotheses in a phylogenetic context. In our analyses, the position of Cycetes (Cycetini) and Thyrsopsocopsis among Thyrsophorini psocids is well resolved, suggesting a dispersal event from the Neotropics for both genera.
193
The variability of the reticulum pattern, ornamentation and outline of the Urocythereis populations of the La Strea Bay is analysed. The results show that the shell features of the form U. distinguenda (Neviani, 1928) (= U. oblonga Brady, 1866) have to be included within the high variability range of U. margaritifera (G.W. Müller, 1894). Consequently, it is suggested that in the upper infralittoral waters of the inlet two (and not three, as stated in previous investigations) species of the genus Urocythereis presently live. A second form, displaying a relatively low variability, is described as a new species, U. ilariae sp. nov.
192
Three new species of Monepidosis Mamaev, 1966, a Holarctic genus of Porricondylinae (Diptera, Cecidomyiidae), are described: M. heterocera sp. nov. from Sweden and Germany, M. scepteroides sp. nov. from Sweden, and M. shikokuensis sp. nov. from Japan. A new porricondyline genus, Antipodosis gen. nov., is introduced for eight new species from New Zealand, named A. australis gen. et sp. nov., A. elongata gen. et sp. nov., A. granvillensis gen. et sp. nov., A. pureora gen. et sp. nov., A. rakiura gen. et sp. nov., A. rotoiti gen. et sp. nov., A. rotoroa gen. et sp. nov., and A. waipapa gen. et sp. nov. Male genitalic morphology indicates that Monepidosis and Antipodosis gen. nov. are closely related, together forming the Monepidosis group of genera, which stands out from the other Porricondylini. Monepidosis spatulata Spungis, 2006, a species originally described from Latvia and Lithuania, is for the first time reported to occur in Sweden.
191
Generally, “ophrys-related” scuticociliates belong to a specialised group of ciliated protozoa that may act as commensals or pathogens of fishes and crustaceans. In the present study, four “ophrystaxa” scuticociliates, i.e., Paramesanophrys typica gen. et sp. nov., Mesanophrys carcini (Grolière & Léglise, 1977) Small & Lynn in Aescht, 2001, Metanophrys sinensis Song & Wilbert, 2000, and Metanophrys similis Song et al., 2002, were collected from Chinese coastal waters or mariculture ponds and investigated. Paramesanophrys gen. nov. is assigned to the family Orchitophryidae and differs from its other genera mainly by the position of the paroral membrane relative to membranelle 1–3, i.e., the membrane extends anteriorly to the posterior end of membranelle 3. The type species P. typica gen. et sp. nov., is defined by an elongated body with the posterior end depressed where the caudal cilium is located; 20 or 21 somatic kineties; double-rowed membranelle 1 with eight to ten basal bodies in each kinety; irregularly multi-rowed membranelle 2 and membranelle 3; scutica comprising c. seven or eight kinetosome pairs; a single macronuclear nodule; and marine habitat. The redescription of the three previously known species can be summarized as follows: 1) improved diagnosis is provided for Metanophrys sinensis Song & Wilbert, 2000 based on the original description and the present study; 2) some population-dependent characteristics of our new Mesanophrys carcini isolate are presented; 3) Metanophrys similis, collected from the South China Sea, resembles the original Qingdao population.
190
The Southeast Asian Pholcus halabala species group is revised and re-delimited, based mainly on field observations (life color pattern, web design, position of egg-sac when carried by female, microhabitat) and ultrastructure (silk spigots, modifications of male cheliceral apophyses). The core group includes six leafdwelling species that have distinctive color patterns in life specimens (black and white or yellowish abdominal marks, dark pattern on posterior half of carapace) and build round to oval silk platforms on the undersides of leaves. Seven further species are tentatively assigned to the group pending further study. Several species originally assigned to the Pholcus halabala group are transferred to three newly proposed species groups, the Ph. krabi, Ph. buatong, and Ph. andulau groups. Nine species are newly described, four in the Ph. halabala group (Ph. khaolek Huber, sp. nov.; Ph. kuhapimuk Huber, sp. nov.; Ph. lintang Huber, sp. nov.; Ph. ubin Huber, sp. nov.); three in the Ph. krabi group (Ph. kipungit Huber, sp. nov.; Ph. krabi Huber, sp. nov.; Ph. narathiwat Huber, sp. nov.); one in the Ph. buatong group (Ph. buatong Huber, sp. nov.); and one in the Ph. andulau group (Ph. lambir Huber, sp. nov.). The females of Ph. satun Huber, 2011 and Ph. schwendingeri Huber, 2011 (both members of the buatong group) are newly described.
189
A new genus and species of bostrichid beetle, Octomeristes gen. nov. and Octomeristes pusillus gen. et sp. nov., in the tribe Xyloperthini is described from litchi (Litchi chinensis Sonn.) wood in Thailand. The genus is compared to Octodesmus Lesne, 1901, the only other xyloperthine genus with eight-segmented antennae, and to the xyloperthine genera, Xylion Lesne, 1901, Xylionulus Lesne, 1901 and Xylobosca Lesne, 1901. A new combination, Octomeristes minutissimus (Lesne, 1932) comb. nov., is transferred from Octodesmus Lesne, 1901. A lectotype is designated for Octodesmus episternalis Lesne, 1901, the type species of Octodesmus. Octodesmus kamoli Chûjô, 1964 is designated a new synonym of Paraxylion bifer (Lesne, 1932). A key is provided to the species of Octodesmus and Octomeristes gen. nov.
188
Two new alcyonacean-associated species, Hamodactylus paraqabai sp. nov. from Papua New Guinea and the Great Barrier Reef and H. pseudaqabai sp. nov. from Indonesia and Malaysia, are described and illustrated. To evaluate the status of the new species and their relationship within the genus Hamodactylus Holthuis, 1952, we combined morphology and phylogenetic analyses based on the cytochrome c oxidase subunit I (COI) mitochondrial gene. Both new species are closely related, with their mutual genetic divergence reaching 3-4%. They are further most related to Hamodactylus aqabai Bruce & Svoboda, 1983, originally described from the Red Sea. Both new species are distinguished from all other congeners by the presence of multiple teeth distally on the cutting edges of the fingers of the first pereiopods, and, in the case of H. paraqabai sp. nov., by a full reduction of the fixed finger on the second pereiopod chela. In H. pseudaqabai sp. nov. the finger is greatly reduced to a small but distinct stub, and the telson bears only a single pair of dorsal spines, as in H. aqabai. A key for the identification of all six currently known species is proposed.
187
The nine British and Irish species of Enicospilus are revised, mapped and an identification key provided. One species, Enicospilus myricae sp. nov., is described as new; Enicospilus merdarius (Gravenhorst, 1829) is a senior synonym of E. tournieri (Vollenhoven, 1879) syn. nov.; the only available name for E. merdarius auctt. is Enicospilus adustus (Haller, 1885) stat. rev., and a neotype is designated for Ophion adustus Haller, 1885. Enicospilus cerebrator Aubert, 1969 and E. repentinus (Holmgren, 1860) are newly recorded from Britain. Some host data are available for eight of the nine species.
186
Two small, ground and litter-dwelling pholcid species from northern Borneo are described as representatives of a new genus, Hantu gen. nov.: H. kapit gen. et sp. nov. and H. niah gen. et sp. nov. Previous cladistic analyses suggested a closer relationship with the genera Savarna Huber, 2005 and Khorata Huber, 2005 (mainland Southeast Asia) than with the geographically closer genus Aetana Huber, 2005 (Borneo and Philippines to Fiji). Since the two species do not share any of the synapomorphies of Khorata and Savarna while having several synapomorphies on their own (ventral apophysis on male palpal coxa; male palpal trochanter apophysis with small teeth or scales; spines on male femora 1; high density of vertical hairs on male femora; presence of scape on epigynum), they are here proposed as representing a new genus.
185
Taxonomic updates and descriptions of four new species from Yunnan, China are provided: three new species in the genus Pitambara Distant, 1906: P. triremiprocta Wang & Soulier-Perkins, sp. nov., P. impudica Wang & Bourgoin, sp. nov., P. tricorne Wang & Wang, sp. nov., and one new species in the genus Serida Walker, 1857: Serida parenthesisflexuosa Wang & Soulier-Perkins, sp. nov. A new identification key to Pitambara species is provided, as well as to the species of the genus Lacusa Stål, 1862. Lacusa yunnanensis Chou & Huang, 1985 stat. rev. is not considered as a synonym of the species L. fuscofasciata (Stål, 1854) anymore and Lacusa orientalis (Liang, 2000) is transferred to the genus Acothrura Melichar, 1915 as Acothrura orientalis (Liang, 2000) comb. nov.
184
We revise the Panjange nigrifrons group in Borneo and document an unexpected diversity in western Sarawak forests. Five species occur within 80 km from Kuching, each species being known from its type locality only. Further species occur east until Niah, but the genus seems to be absent from Sabah. We contrast this with another pholcid genus (Aetana Huber, 2005), which is diverse in Sabah and westward until Niah, but does not seem to occur in central and western Sarawak. Five species are newly described: Panjange kapit Huber, sp. nov., Panjange kubah Huber, sp. nov., Panjange niah Huber, sp. nov., Panjange pueh Huber, sp. nov., Panjange seowi Huber, sp. nov.; Panjange tahai (Huber, 2011) comb. nov. is transferred from Pholcus.
183
An updated classification of Polyalthia in Peninsular Malaysia is presented. A synopsis (listing of species with synonymy and typification, and keys to species) is presented for the genera Huberantha, Maasia, Monoon and Polyalthia sensu stricto. One new species (Polyalthia pakdin I.M.Turner & Utteridge sp. nov.) is described and a conservation assessment presented for it. Monoon xanthopetalum Merr. represents a new record for Peninsular Malaysia. Six new lectotypes are designated.
182
Two new species of potamonautid freshwater crabs are described from the Imatong Mountains and Mount Moroto in northern Uganda, East Africa, and a third highland species, Potamonautes amalerensis (Rathbun, 1935) stat. rev. from Mount Kadam is re-diagnosed based on examination of the holotype. All three species are endemic to a different mountain range and their collection localities indicate a distinct preference for higher altitudes. Diagnoses, illustrations and distribution maps are provided for these taxa, and they are compared to similar species from the region. The conservation status of all three species is discussed.
181
A new genus in the tribe Issini (Hemiptera: Fulgoromorpha: Issidae) is described from South China: Orbita Meng & Wang, gen. nov., its type species Orbita parallelodroma Meng & Wang, gen. et sp. nov. (China: Fujian) is described and illustrated. In addition, one new species of Neokodaiana Yang, N. minensis sp. nov. is described and illustrated from the same locality as the new genus. A key to the genera of Issini from China and neighbouring countries is provided.
180
Bees of the family Halictidae Thomson, 1869 from Dominica, Lesser Antilles (Hymenoptera: Apoidea)
(2016)
The bees of the family Halictidae Thomson, 1869 from Dominica are reviewed. Seven new species are described and illustrated: Lasioglossum (Dialictus) kalinago sp. nov., L. (D.) dominicense sp. nov., L. (D.) kilpatrickae sp. nov., L. (Habralictellus) roseauense sp. nov., Sphecodes diablotinus sp. nov., S. albifacies sp. nov. and Habralictus antillarus sp. nov. A description and images of the previously unknown female of Microsphecodes dominicanus (Stage, 1972) are provided. In total, eleven species are recognized: eight nest-building species and three kleptoparasites. All halictid species from Dominica are currently known only from the island. A key to halictid bees from Dominica is provided.
179
The present work provides the first record of the genus Dinotrema Foerster, 1862 in the Neotropical region. Four new Neotropical species are described and illustrated: D. multiareolatum Peris-Felipo sp. nov., D. plaumanni Peris-Felipo sp. nov., D. subbidentatum Peris-Felipo sp. nov., and D. teutoniaense Peris-Felipo sp. nov. The following new combinations are suggested for Nearctic species: Dinotrema angusticornis (Fischer, 1969) comb. nov., D. armillariae (Fischer, 1969) comb. nov., D. bucculatricis (Fischer, 1969) comb. nov., D. caudatulum (Fischer, 1969) comb. nov., D. clayensis (Fischer, 1969) comb. nov., D. communis (Fischer, 1969) comb. nov., D. disstriae (Fischer,1969) comb. nov., D. pauperum (Fischer, 1969) comb. nov., D. saileri (Fischer, 1969) comb. nov., D. shannoni (Fischer, 1969) comb. nov. and D. sylvaticae (Fischer, 1969) comb. nov. An identifi cation key of the all New World Dinotrema species is provided.
178
In this study we analyze the calcarean sponge diversity of the Adriatic Sea, the type locality of some of the first described species of calcarean sponges. Morphological and molecular approaches are combined for the taxonomic identification. Our results reveal six species new to science and provisionally endemic to the Adriatic Sea (Ascandra spalatensis sp. nov., Borojevia croatica sp. nov., Leucandra falakra sp. nov., L. spinifera sp. nov., Paraleucilla dalmatica sp. nov., and Sycon ancora sp. nov.), one species previously known only from the Southwestern Atlantic (Clathrina conifera), and three already known from the Adriatic Sea (Ascaltis reticulum, Borojevia cerebrum, and Clathrina primordialis). We confirm the presence of the alien species Paraleucilla magna in the Adriatic and again record Clathrina blanca, C. clathrus, and C. rubra. We emend the description of the genus Ascaltis, propose a lectotype for Borojevia cerebrum and synonymise B. decipiens with B. cerebrum. A checklist of all calcarean species previously and currently known from the Adriatic Sea (39 species) is given. The Central Adriatic is indicated as the richest calcarean sponge fauna sector; however, the biodiversity of this class is underestimated in the whole Adriatic Sea and new systematic surveys are desirable.
177
The new genus Geotypodon gen. nov. is described. It includes two species from the Udzungwa Mountains: G. millemanus gen. et sp. nov. (type species) and G. submontanus gen. et sp. nov., one species from nearby Iringa: G. iringensis gen. et sp. nov., and 18 previously described species hitherto incorrectly assigned to Odontopyge Brandt, 1841.
176
Two species of Tomoceridae were found near Dalat, southern Vietnam. Tomocerus ocreatus Denis, 1948 is redescribed based on a neotype specimen. Previous records of Tomocerus ocreatus in non-type localities are reevaluated. A new species Tomocerina annamitica sp. nov. is described. The new species is mainly characterized by its small body size, pointed tenent hair, compound dental spines and the absence of intermediate teeth on mucro.
175
Two new species from South Africa, Dactylonotus nigricorpus sp. nov. and Dactylonotus tsitsikamma sp. nov., are described and illustrated. D. nigricorpus sp. nov. differs from all other species of the genus in the black body, the smaller size and the shorter antenna. D. tsitsikamma sp. nov. is peculiar in the genus in bearing a flag of long setae on the fifth segment of the fore tarsus. An identification key to 6 Afrotropical species of the genus is provided.
174
A new species of Fidelia Friese, 1899 is described from southern Africa: Fidelia (Fideliopsis) whiteheadi Litman & Kuhlmann sp. nov. Diagnostic characters are provided to distinguish this species from others in the genus, particularly from the closely related F. hessei; an updated description for Fidelia hessei is also given. The host plant preferences and seasonal activity of F. whiteheadi Litman & Kuhlmann sp. nov. and F. hessei are discussed. Finally, a revised, illustrated key to species of the genus Fidelia is presented.
173
The genus Profundiconus Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in Profundiconus are discussed. In particular, we studied Profundiconus material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial cox1 gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of Profundiconus based on their shell and radular morphologies, and are introduced here as five new species: Profundiconus maribelae sp. nov. from the Solomon Islands; P. virginiae sp. nov. from Chesterfield Plateau (New Caledonia); P. barazeri sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); P. puillandrei sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and P. neocaledonicus sp. nov. from New Caledonia. Furthermore, Profundiconus teramachii forma neotorquatus (da Motta, 1984) is raised to specific status as P. neotorquatus (da Motta, 1984).
172
New species of “giant” plume moths of the genus Platyptilia (Lepidoptera, Pterophoridae) from Uganda
(2016)
This paper describes two new species of plume moths from the group of the so-called “giant” Platyptilia Hubner, 1825: Platyptilia fletcheri Ustjuzhanin & Kovtunovich sp. nov. and P. stanleyi Ustjuzhanin & Kovtunovich sp. nov. Both species were collected in the Rwenzori Mountains in Uganda and Rwanda, respectively. Platyptilia stanleyi Ustjuzhanin & Kovtunovich sp. nov. exceeds all the known African species of Pterophoridae in its wingspan of 49 mm.
171
Two new species of the genus Sectonema from natural habitats of northern Vietnam are studied. This paper includes their descriptions, measurements, line illustrations, and light microscope (LM) and scanning electron microscope (SEM) pictures. Sectonema tropicum sp. nov. is characterized by a 2.56– 3.24 mm long body, 19–21 μm broad lip region, odontostyle 20–21 μm long at its ventral side, 730– 834 μm long neck, pharyngeal expansion occupying 52–59% of total neck length, uterus a simple tube-like structure 150–242 μm long or 1.2–2.5 times the body diameter, pars refringens vaginae present, V = 48–52, short (31–40 μm, c = 70–91, c’ = 0.5–0.6) and rounded tail, 91–97 μm long spicules, and only one weakly developed ventromedian supplement. Sectonema vietnamense sp. nov. is characterized by its slender (a = 33–49) and 2.71–4.25 mm long body, 14–16 μm broad lip region, odontostyle 8–9 μm long at its ventral side, 716–918 μm long neck, pharyngeal expansion occupying 63–67% of total neck length, uterus simple and 209–242 μm long or 2.5–2.9 times the corresponding body diameter, pars refringens vaginae absent, V = 54, short (34–39 μm, c = 70–115, c’ = 0.6–0.8) and rounded tail, 59–75 μm long spicules, and three or four irregularly spaced ventromedian supplements bearing hiatus. Both species are also characterized by their nearly continuous lip region, an atypical feature in this genus. Molecular analysis of S. tropicum sp. nov. confirms that Sectonema is a natural (monophyletic) taxon, very close to Metaporcelaimus.
170
The Lycocerus hanatanii species group is revised, with the addition of seven taxa: L. araticollis (Fairmaire, 1897), L. nigripennis (Pic, 1938), L. griseopubens (Pic, 1928), L. yitingi Hsiao & Okushima sp. nov., L. aurantiacus Hsiao & Okushima sp. nov., L. evangelium Hsiao & Okushima sp. nov. and L. kintaroi Hsiao & Okushima sp. nov. Supplementary descriptions of the males of L. araticollis and L. griseopubens are provided. Lycocerus nigripennis (Pic, 1938) and L. pictus (Wittmer, 1983) are redescribed in detail. Each species is provided with photos or illustrations of genitalia of both sexes and abdominal ventrite VII of the female if available. Distribution maps and a key to the species of the L. hanatanii species group are presented. In addition, the monophyly of the L. hanatanii species group is supported based on a morphological phylogenetic analysis.
169
We describe several new species of the previously monotypic Panjange lanthana species group from the Philippines and document their extraordinary morphology. Some species show strong male genital asymmetry, a phenomenon that seems to be exceedingly rare in spiders. Males of most species have eye stalks, and in two species these eye stalks are among the longest ever recorded in spiders. Some species show a tendency for male genital (pedipalp) elongation, and one species has the longest and thinnest palps ever recorded in Pholcidae. A cladistic analysis is performed including all described and several undescribed species of Panjange (except for one “problem species”), supporting the lanthana group and its close relationship with members of the possibly paraphyletic cavicola group. The following eight new species are described: Panjange malagos Huber sp. nov.; Pa. casaroro Huber sp. nov.; Pa. camiguin Huber sp. nov.; Pa. hamiguitan Huber sp. nov.; Pa. isarog Huber sp. nov.; Pa. dinagat Huber sp. nov.; Pa. marilog Huber sp. nov.; Pa. bukidnon Huber sp. nov.
168
This study deals with the biodiversity and distribution of cavernicolous Amphipoda in caves of the Arabika massif (Western Caucasus). The Sarma, Trojka and Orlinoe Gnezdo caves were explored during speleological expeditions over the years 2011–12. Two new species of Amphipoda were found: a sub-surface dweller Zenkevitchia sandroruffoi sp. nov. is reported from the Sarma, Trojka and Orlinoe Gnezdo caves at depths from -30 m to -350 m; the second one, a deep dweller Adaugammarus pilosus gen. et sp. nov. is reported from the Sarma Cave at depths of -1270 to -1700 m. Adaugammarus gen. nov. shares similarities with Typhlogammarus Schäferna, 1907 and Zenkevitchia Birstein, 1940. The species Anopogammarus birsteini Derzhavin, 1945 is also re-described herein based on new samples that suggest close affinity of this species with the family Gammaridae. The original taxonomic combination is resurrected for Zenkevitchia revazi Birstein & Ljovuschkin, 1970, comb. resurr. (from Anopogammarus Derzhavin, 1945). To accommodate morphologically different species in the genus Zenkevitchia, two new groups are proposed. These are the admirabilis-group (Z. admirabilis Birstein, 1940 and Z. yakovi Sidorov, 2015) and the sandroruffoi-group (Z. sandroruffoi sp. nov. and Z. revazi). An updated molecular (mt-cox1) phylogeny, an identification key to the genera and a distribution map for the typhlogammarid amphipod species of Transcaucasia are provided.
167
Fifteen new species of Begonia L. from Sumatra are described and illustrated, in Begonia sect. Bracteibegonia (B. beludruvenea M.Hughes sp. nov. and B. jackiana M.Hughes sp. nov.), B. sect. Petermannia (B. harauensis Girm. sp. nov.), B. sect. Platycentrum (B. leuserensis M.Hughes sp. nov.), B. sect. Reichenheimia (B. fl uvialis M.Hughes sp. nov., B. halabanensis M.Hughes sp. nov., B. karangputihensis Girm. sp. nov., B. kemumuensis M.Hughes sp. nov., B. korthalsiana Miq. ex M.Hughes sp. nov., B. kudoensis Girm. sp. nov., B. lilliputana M.Hughes sp. nov., B. olivacea Ardi sp. nov., B. raoensis M.Hughes sp. nov., B. simolapensis Ardi sp. nov.) and B. sect. Sphenanthera (B. pseudoscottii Girm. sp. nov.). Using the International Union for the Conservation of Nature criteria, 6 are considered to be Least Concern, 5 Vulnerable and 4 Data Deficient. A key to 58 of the 63 currently accepted Begonia species in Sumatra is provided.
166
The taxonomy of the deep-water homolid crabs Moloha grandperrini Guinot & Richer de Forges, 1995 and M. alisae Guinot & Richer de Forges, 1995 is re-examined, and the types redescribed and figured. Moloha alisae is reported from South Africa for the first time. A new species with an inflated carapace, M. tumida sp. nov., is also described from southern India and compared with its closest congeners.
165
Following ICZN (1999) Article 79 Chapter 17 (http://www.nhm.ac.uk/hosted-sites/iczn/code/), we, with the full support of the international community of rotifer researchers as expressed during subsequent international Rotifera symposia, developed a Candidate Part of the List of Available Names for species and genera of Rotifera from the start of zoological nomenclature to the year 2000.
164
Niphargus dancaui sp. nov., previously referred to as Niphargus cf. stygius, was sampled from various groundwater sites in and near the town of Mangalia (SE Romania) and described with Movile Cave (a sulfidic, chemoautotrophically based ecosystem) as type locality. A short comparison with Niphargus stygius specimens from Slovenia was made, together with a morphological analysis of interpopulational variability. Males of N. dancaui sp. nov. were relatively large (17 mm), with long antennae, pereiopods and uropod III. Females were slightly smaller, with shorter antennae, pereiopods and uropod III. Interpopulational variability was noticed in the chaetotaxy of the telson lobes and uropod III. N. dancaui sp. nov. is morphologically very close to N. lessiniensis and N. tridentinus, two species present in northern Italy, but distinct genetically from them based on 28S rRNA sequences. Instead, the closest relative of N. dancaui sp. nov. sequenced so far for this marker is N. montanarius, which inhabits a sulfidic cave system in central Italy. The work presented here contributes to our knowledge of groundwater crustacean biodiversity in general and of the systematics of the genus Niphargus in particular.
163
Ballomma, a new Afrotropical genus in the Cryptothelinae (Araneae, Zodariidae): eyes on the run
(2015)
Ballomma gen. nov. is described in the zodariid subfamily Cryptothelinae. It is characterized by the pairs of adjacent anterior median eyes and anterior lateral eyes and triangular palpal tarsus in the female, the concave tegulum with thin embolus in the male. Apart from the type species B. erasmus gen. et sp. nov. (♂♀), the genus contains B. haddadi gen. et sp. nov. (♂♀), B. neethlingi gen. et sp. nov. (♂♀), and B. legala gen. et sp. nov. (♀). A key to the species is provided. The restricted distribution of the genus is discussed.
162
The previously poorly known Southeast Asian spider genus Aetana Huber, 2005 is revised. Fifteen species are newly described, and the first SEM data and a first phylogenetic analysis of the genus are presented. Four species groups are well supported, one restricted to Borneo, two restricted to the Philippines, and one ranging from the Philippines to Fiji. The cladistic analysis and field observations suggest that the ancestor of Aetana built its web close to the ground, in confined spaces among and under rocks and logs. In at least two cases, evolutionary shifts of microhabitat resulted in species being adapted to life in higher forest strata, with correlated morphological and behavioral changes (lighter coloration; longer abdomen; additional sheet in web or more strongly domed web). The following species are newly described: A. abadae Huber, sp. nov., A. baganihan Huber, sp. nov., A. banahaw Huber, sp. nov., A. kiukoki Huber, sp. nov., A. libjo Huber, sp. nov., A. loboc Huber, sp. nov., A. lozadae Huber, sp. nov., A. manansalai Huber, sp. nov., A. ocampoi Huber, sp. nov., A. paragua Huber, sp. nov. and A. pasambai Huber, sp. nov. from the Philippines; A. gaya Huber, sp. nov., A. indah Huber, sp. nov., A. lambir Huber, sp. nov. and A. poring Huber, sp. nov. from northern Borneo. The female of A. kinabalu Huber, 2005 is newly described. A potential case of female genital dimorphism is documented in A. ocampoi Huber, sp. nov.

The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity. All the terrestrial isopods known from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns. Twenty-seven species, belonging to 15 genera and six families, are known, of which 16 species are considered to be exclusively from subterranean ecosystems, i.e., troglobionts. Trichoniscidae is the most diverse family. Seven species in the family Trichoniscidae and one species in the family Styloniscidae are described as new (all with Reboleira & Taiti as authors): Trichoniscoides bellesi sp. nov. from the Montejunto Massif; T. sicoensis sp. nov. from the Sicó Massif; Metatrichoniscoides salirensis sp. nov. from the typhonic valley of Caldas da Rainha; Troglonethes olissipoensis sp. nov. from the Lisbon Peninsula; T. arrabidaensis sp. nov. from the Arrábida Massif; Miktoniscus longispina sp. nov. from the Sicó Massif and Cesaredas Plateau; Moserius inexpectatus sp. nov. from the Estremenho Massif; and Cordioniscus lusitanicus sp. nov. from Alentejo and Algarve, the southernmost provinces of Portugal. The subgenus Trogleluma Vandel, 1946 (Armadillidiidae) is raised to genus level. In this geographic region terrestrial isopods are the richest group of cave-adapted animals.
160
The genus Savarna Huber, 2005 was previously one of the most poorly known Pholcinae genera. Less than 20 specimens (representing four nominal species) were available worldwide; nothing was known about ultrastructure, natural history, or relationships. We present the first SEM data, supporting the position of the genus in Pholcinae outside the Pholcus group of genera and weakly suggesting a closer relationship with the genera Khorata Huber, 2005, Spermophorides Wunderlich, 1992, and two undescribed species of unknown affinity from Borneo. We provide the first data about microhabitat, web structure, and reaction to disturbance. We clarify the type locality of Savarna tessellata (Simon, 1901) (“Jalor, Biserat”) and describe topotypical material. We describe the previously unknown male of Spermophora miser Bristowe, 1952 and transfer the species (that was previously considered incertae sedis) to Savarna as Savarna miser (Bristowe, 1952) comb. nov. Savarna baso (Roewer, 1963) is newly synonymized with S. miser. We describe the most northern species in the genus, Savarna kaeo sp. nov., and provide amendments to the descriptions of all previously described species.
159
A new monospecific genus, Pseudostegopterus gen. nov., endemic to the northwestern region of South Africa, is erected. The type species is described as Pseudospegopterus melonthinoides sp. nov. and is currently known only from male specimens. A provisional dichotomic key of the African Trichiina genera is also provided, in order to facilitate the identification of male specimens to the genus level.
157
Redescription of some species of Bryozoa described by J. Jullien and L. Calvet in the NE Atlantic
(2015)
Five species described by Jullien and/or Calvet from the NE Atlantic are redescribed and stabilized by typification: Hippothoa amoena, Schizoporella confusa, S. jullieni, S. ovum and Smittia guernei. Three new synonymies are established: Schizoporella jullieni with Hippothoa amoena, S. ovum with Escharina alderi, and Escharella pseudopunctata with Smittia guernei. A new trypostegid genus, Pulpeirina gen. nov., is erected for H. amoena. Three new combinations are introduced.
158
Three new species of the order Monhysterida are described based on specimens obtained at depths of 8081 and 9177 m in the Kermadec Trench. Thelonema clarki sp. nov. is characterised by a large body size (3230–4461 μm), short cylindrical buccal cavity, gubernaculum without apophyses, and long conico-cylindrical tail. This is the first record of the genus since its original description over two decades ago from the Peru Basin. Metasphaerolaimus constrictus sp. nov. is characterised by a relatively long body (1232–1623 μm), slightly arcuate spicules without gubernaculum, and conico-cylindrical tail with inner cuticle conspicuously thickened immediately anterior to cylindrical portion. Monhystrella kermadecensis sp. nov. is characterised by a circle of papillose outer labial sensillae slightly anterior to the four short cephalic setae, gubernaculum with caudal apophyses, the presence of distinct cuticularised piece along anterior vaginal wall, and a relatively short conical (males) or conico-cylindrical tail (females) with conical, ventrally-curved spinneret. M. kermadecensis sp. nov. can be differentiated from all other species of the genus, and, indeed, the entire family, based on the variable position of the anterior gonad relative to the intestine. The new species is classified within the Monhysteridae, and not the closely-related Xyalidae, based on the small body size, a smooth cuticle, and the presence of six outer labial papillae and only one testis. Further work is required to clarify the placement of M. kermadecensis sp. nov. relative to other monhysterid genera. A tabular key to all ten valid Metasphaerolaimus species is presented.

The collection of deep-sea pebble crabs (Leucosioidea) during the BIOPAPUA Expedition, comprising 8 species, including a species new to science, is significant because although the previously described species had not been recorded from the Bismarck and western Solomon Seas, they occurred in at least one nearby location (New Caledonia, Vanuatu, Solomon Is). Praebebalia fungifera sp. nov. is described and illustrated. It differs from its closest congener, P. septemspinosa Sakai, 1983, in bearing fungiform granules dorsally on carapace, shorter chelipeds, the relatively stout male first gonopod with a preapical row of setae and the beak-like tip, as compared to the rounded granules dorsally on the carapace, greatly elongate chelipeds and the slim, elongate, distally curved gonopod of P. septemspinosa, preapically set with very long setae and a hook-like tip.
154
Amage imajimai sp. nov., a new species of Ampharetidae (Annelida: Polychaeta) from Japanese waters
(2015)
A new polychaete species of the family Ampharetidae, Amage imajimai sp. nov., is described from deep waters of Sagami Bay, Japan. It is characterized by the possession of four pairs of branchiae, twelve thoracic uncinigers, eleven abdominal uncinigers, and the lack of thoracic notopodial cirri. The new species is named in honor of the renowned Japanese polychaetologist Minoru Imajima. An identification key for all Amage species from Japanese waters is provided.
153
Molecular phylogenetic analysis has demonstrated that the genus Gallinula is not monophyletic and comprises four major lineages. A review of the nomenclature of Gallinula shows that generic names are available for three lineages but that a fourth is as yet unnamed. A new monotypic genus, Paragallinula gen. nov., is described for Lesser Moorhen (Gallinula angulata Sundevall, 1850).
152
The new genus Palindroma gen. nov. is described in the Cryptothelinae, Zodariidae. Apart from the type species, P. morogorom gen. et sp. nov. (♂♀), the genus contains P. aleykyela gen. et sp. nov. (♂), P. avonova gen. et sp. nov. (♂♀), P. sinis gen. et sp. nov. (♂) and the somewhat aberrant species P. obmoimiombo gen. et sp. nov. (♂). The four typical representatives of the genus are characterized by the profile of the carapace with a slight dip, the absence of precoxal sclerites and the characters of the male palp with enlarged tibia, large subtegulum and tegular retrolateral knob. The genus occurs in miombo-woodland and coastal forest in East and Central Africa and this peculiar distribution is discussed. A key to the males of the Palindroma species is provided. Specimens of Palindroma have a particularly well-developed tibial process fitting in a shallow metatarsal pouch on all legs in both sexes. Although less conspicuous in some derived taxa, the feature appears to be present in all representatives of the Zodariidae, but not in possible sister-group taxa and is thus an autapomorphy of the family.
151
Two new junior synonyms, Pseudomesitius Duchaussoy, 1916 syn. nov. and Triglenus Marshall, 1905 syn. nov., for the genus Bradepyris Kieffer, 1905 are proposed and a new diagnosis for the genus is given. Two new species (based on males) from the Saharo-Arabian region are here described: Bradepyris jordanicus, sp. nov. and B. baleariensis, sp. nov. A brief revision, with a key to the males and females of all species of this genus, and the first male genitalia descriptions are also provided.
150
The genus Aquattuor Frederiksen, 2013 is revised. A. denticulatus Frederiksen, 2013 (type species) from the East Usambara Mts, Tanzania, is redescribed, and six new species are described: A. claudiahempae sp. nov. from Mt. Kilimanjaro, Tanzania, and five species from the Udzungwa Mts, Tanzania: A. longipala Enghoff sp. nov., A. major Enghoff sp. nov., A. stereosathe Enghoff sp. nov., A. submajor Enghoff sp. nov., and A. udzungwensis Enghoff sp. nov.
149
Twenty-three species of cheilostome bryozoans are described from the Malaysian islands of Penang and Langkawi based on a brief reconnaisance survey of shore localities. These are the first bryozoans to be formally described from either island and they demonstrate the potential for further research on these neglected suspension feeders. Of the 23 species recorded, 12 are anascans, half of which are malacostegines, and 11 are ascophorans. The new combinations Acanthodesia falsitenuis (Liu, 1992), A. perambulata (Louis & Menon, 2009) and A. irregulata (Liu, 1992) are introduced. Most of the species recorded are widespread in the Indo-Pacific, and some are apparently globally distributed in the tropics and subtropics, including the invasive fouling species Bugula neritina, Hippoporina indica and Schizoporella japonica, as well as the coral reef associates Cranosina coronata and Hippopodina feegeensis. Plastic debris and glass bottles were encrusted by Jellyella eburnea, a coloniser of floating biological and man-made objects that is becoming widespread in the tropics and subtropics of the world’s oceans.
148
Three new species of Eburiini are described: Beraba hovorei sp. nov. from Ecuador, Eburella migueli sp. nov from Colombia and Susuacanga marcelae sp. nov. from Mexico. A new combination, Quiacaua vespertina (Monné & Martins, 1973) comb. nov., and the transfer of Eburia (Eburia) stroheckeri Knull, 1949 to Eburia (Eleutho) Thomson, 1864 are proposed. A key to species of Beraba Martins, 1997, Eburella Monné & Martins, 1973 and Quiacaua Martins, 1997 is provided. Moreover, the geographical distribution for 15 species of Eburiini is expanded. A lectotype and a paralectotype for Volxemia dianella Lameere, 1884 are designated.
147
Four new species of the genus Caccothryptus (Coleoptera: Limnichidae) are described: C. taiwanus from Taiwan; C. orion from Okinawa; C. tibetanus and C. chayuensis from Tibet. All the species belong to the testudo species group (sensu Hernando & Ribera 2014). Additional specimen data and an updated species list are also given, and C. testudo Champion, 1923 is newly recorded from Thailand.
146
Chiraziulus is a highly disjunct, hitherto monotypic genus of cambalid millipedes, geographically isolated in Iran by more than 7000 km from its presumed closest relatives in East Asia and North America. Recent fieldwork in caves of Iran has provided several specimens of this genus, allowing the description of Chiraziulus troglopersicus sp. nov. The intraspecific variability of the type species, C. kaiseri Mauriès, 1983, is illustrated with scanning electron micrographs. Chiraziulus is characterized by exceedingly long microtrichose gonopod flagella which from their insertion points on the posterior face of the anterior gonopod coxites first point distad instead of basad or basad-posteriad as in most other flagelliferous Cambalidea (and Julida), then traverse a groove on the mesal surface of the anterior gonopod coxites, making a full (360°) loop. The same feature is also illustrated for the first time in the genus Cambala. The patterns and prevalence of the infection with a species of ectoparasitic fungus of the genus Rickia (order Laboulbeniales) in the type material of C. kaiseri is described. An updated review of the cave-adapted fauna of Iran is given.
145
Keys and diagnoses of North European aphids (Hemiptera, Aphidoidea) associated with mosses, horsetails and ferns are given, based on fresh and freeze-dried material. Numerous externally visible and thus informative characters, that are absent in cleared, slide-mounted specimens, such as body shape colours, wax coating and pattern etc., are utilized. Most of the species are illustrated by photographs of live specimens and drawings. Root-feeding species living in the moss layer or otherwise often present in moss samples are also included, even if their hosts were spermatophytes. The combination of colour images and diagnoses, utilizing easily observed characters, allows the identification of a large number of species already in the field, and many more at home with the aid of a stereo microscope. Host plant relationships and association with ants are summarised, including new records. Brief accounts on aphid life cycles, freeze-drying preparation techniques, etc. are also given to support the use of the keys.
144
A new sepioline species, Sepiola boletzkyi sp. nov. (Cephalopoda: Sepiolidae), is described based on two specimens from the Aegean Sea (eastern Mediterranean). The type specimens are lodged in the Ege University Faculty of Fisheries Museum of Izmir (Turkey). The new species belongs to the Sepiola atlantica group sensu Naef, hence it is compared with the species in this group, namely Sepiola affinis, Sepiola atlantica, Sepiola bursadhaesa, Sepiola intermedia, Sepiola robusta, Sepiola rondeletii, Sepiola steenstrupiana and Sepiola tridens. The male of S. boletzkyi sp. nov. differs from all the others in having the combination of homomorphous ventral arm tips, eight enlarged suckers, subdivided into two groups, in the dorsal row of the distal part of the hectocotylus and a dorsal lobe complementing the copulatory apparatus. In females of S. boletzkyi sp. nov. the bursa copulatrix is large and, unlike all other species in the genus, has a large fungiform process towards the mantle wall. The discovery of S. boletzkyi sp. nov. increases to 12 the number of NE Atlantic- Mediterranean species of Sepiola.
143
Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov. and L. prometea Delsinne & Donoso sp. nov., based on workers collected in the leaf litter and soil of the Andes of southern Ecuador. Both species belong to the L. biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed in L. prometea sp. nov. but seems absent in L. copalinga sp. nov. We provide a COI DNA barcode for both species and a revised key for the worker caste of all known species in the genus. We also describe a single male identified as a potential new Leptanilloides species on the basis of morphology. Furthermore, its mitochondrial COI gene sequence does not match any previously barcoded species. However, we refrain from giving it a specific name because of our lack of knowledge about the worker caste. So far, half of the 14 Leptanilloides species have been discovered above 1500 m in the mountain forests or páramos of the Ecuadorian Andes, confirming, if needed, the biological significance of these threatened habitats.
142
Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891) placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944). Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.

The Earwig Collection (Dermaptera) of the Manchester Museum, UK, with a complete type catalogue
(2015)
This paper presents a description of the worldwide Dermaptera collection of the Manchester Museum, UK. In total, the collection contains over 16,700 specimens and represents 835 species and subspecies (approximately 44% of the Dermaptera world fauna). The composition of the collection is described and a brief account is given of its history and those instrumental in its development, notably W.D. Hincks (1906–1961) and A. Brindle (1915–2001). Correspondence held at the museum relating to their work on Dermaptera is listed and examples relating to Labidura herculeana (Fabricius, 1798) and some of the parasitic earwigs in the collection are explored. Finally, a complete type catalogue of the Manchester Museum’s Dermaptera is presented; it is arranged alphabetically by species name as originally described, with photographs of all holotypes and their corresponding data labels. The collection contains 40 holotypes and 694 secondary types (allotypes, syntypes or paratypes), representing 283 species and subspecies, an estimated 15% of the Dermaptera world fauna.

Actaea grimaldii, a new species of reef crab from Papua New Guinea (Crustacea, Brachyura, Xanthidae)
(2015)
A new species of xanthid crab, Actaea grimaldii, is described from the coral reefs of Papua New Guinea. This species has a distinctive red and white coloration and is closest to Actaea spinosissima Borradaile, 1902, from the Indian Ocean. However, the new species can be distinguished by the arrangement of spines on the carapace, chelipeds and ambulatory legs, and the structure of the male gonopods. Actaea grimaldii sp. nov. has also been confused with A. polyacantha (Heller, 1861), but differs markedly in the carapace armature.
139
A new genus, Campodesmoides gen. nov., is described to only encompass C. corniger sp. nov., from Cameroon. This genus and species is distinguished from the few known species of the small western African family Campodesmidae, all currently in Campodesmus, by the much longer antennae and legs, the normal pore formula with ozopores borne on porosteles, and the suberect and distally twisted gonopod, coupled with peculiar horns on a few anterior postcollum segments. A new Campodesmus is also described, C. alobatus sp. nov., from Ivory Coast, which differs from congeners primarily in the lack of a dorsal/lateral lobe on the otherwise usual and strongly subcircular gonopod telopodite, albeit the latter is not directed mesad, but held subparallel to the main body axis.
138
A new species of Rhaphiostylis, R. minima sp. nov. from Liberia and Ivory Coast, is described and illustrated here. It is characterised by its comparatively small size, an ovate to lanceolate leaf blade with long drip tip and a partly glabrous ovary that is in shape in between those of R. elegans Engl. and R. preussii Engl. Rhaphiostylis elegans is lectotypified and illustrated here.
137
Three species of the genus Pseudocandona Kaufmann, 1900 and one of the genus Undulacandona Smith, 2011, collected from freshwater habitats in Japan, are described. The Pseudocandona species, Pseudocandona becca sp. nov., Pseudocandona atmeta sp. nov. and Pseudocandona falcula sp. nov., all belong to the rostrata-group. Previous reports of Pseudocandona rostrata (Brady & Norman, 1889) and Pseudocandona sarsi (Hartwig, 1899) from Japan are reassessed and are subsequently synonymized with Pseudocandona tenuirostris Hiruta & Mawatari, 2013 and Pseudocandona falcula sp. nov. respectively. Undulacandona colymba sp. nov. is only the second to be described in this genus. Like the type species of the genus, it is a stygobiont, collected from groundwater in Shiga Prefecture. Additional records of Candona candida (O.F. Müller, 1776), are presented herein; so far, Japanese records of this species are restricted to the eastern part of Hokkaido.
136
Twelve species in total are recognized for the subgenus Lasioglossum (Dialictus) Robertson, 1902 from Japan, the Korean Peninsula and Taiwan. Lasioglossum (Dialictus) alishanense sp. nov. and L. (D.) taiwanense sp. nov. from Taiwan, are described as new. Four species are recorded fromn the following localities for the first time: L. (D.) miyabei Murao, Ebmer & Tadauchi, 2006 from the Korean Peninsula (South Korea); L. (D.) ellipticeps (Blüthgen, 1923), L. (D.) virideglaucum Ebmer & Sakagami, 1994 and L. (D.) viridellum (Cockerell, 1931) from South Korea. Lasioglossum (Dialictus) atroglaucum (Strand, 1913) is redescribed, L. (D.) ellipticeps, L. (D.) problematicum (Blüthgen, 1923), L. (D.) virideglaucum, and L. (D.) viridellum are supplementary described. A key to species is provided. Bionomical data, such as fl ight and fl ower records or habitat, are reported for some species. The distributions of all species are mapped. DNA barcodes of L. (D.) miyabei, L. (D.) pseudannulipes (Blüthgen, 1925), and L. (D.) virideglaucum are provided.
135
Two new genera and nine new species of hydroids are described based on deep-water material collected from off New Caledonia during various expeditions of the French Tropical Deep-Sea Benthos program. Caledoniana gen. nov., provisionally included in the family Sertulariidae Lamouroux, 1812, presently comprises three new species, viz. C. alata sp. nov., C. decussata sp. nov., and C. microgona sp. nov., while an additional group of three new species, is accommodated in the new sertulariid genus Solenoscyphus gen. nov.: S. candelabrum sp. nov., S. decidualis sp. nov., and S. striatus sp. nov. Furthermore, three new species of Hincksella Billard, 1918 (family Syntheciidae Marktanner- Turneretscher, 1890) are described, namely H. cornuta sp. nov., H. neocaledonica sp. nov., and H. similis sp. nov.
134
Morphological (shell) and molecular examination of a large suite of specimens of pleurotomariids from around New Caledonia and the Coral Sea reveals the existence of four species in the complex of Perotrochus caledonicus: Perotrochus deforgesi Métivier, 1990 and P. pseudogranulosus sp. nov. live allopatrically on the plateaus and guyots of the Coral Sea; Perotrochus caledonicus Bouchet & Métivier, 1982 and Perotrochus wareni sp. nov. live sympatrically - but essentially not syntopically - on the slopes of New Caledonia, Norfolk Ridge and the Loyalty Ridge. All species live in the 300–500 m interval, and together form a significant component of the mollusc fauna living on hard bottoms in the SW Pacific, with individual dredge hauls containing up to 25 specimens of Perotrochus.
133
New and interesting Surirella taxa (Surirellaceae, Bacillariophyta) from the Congo Basin (DR Congo)
(2015)
Two new diatom taxa belonging to the genus Surirella, S. ebalensis and S. congolensis, are described from material of the Congo Basin, downstream Kisangani, DR Congo. The first taxon is a small, rather common species in the studied material; the second a somewhat larger diatom that was only sporadically observed. The morphology of both taxa is examined with light and scanning electron microscopy. The differences between the new and other closely related taxa such as S. agonaensis and S. bonsaensis, and S. takoradiensis, S. tenuissima and S. pseudotenuissima, respectively, are discussed.
132
Pardosa benadira Caporiacco, 1940 is redescribed, including the hitherto unknown female. The species is here transferred to the genus Wadicosa Zyuzin, 1985. Previously known only from its type locality in Somalia, additional localities for P. benadira in Somalia and Kenya are given. Male and female W. cognata sp. nov. (Kenya: Lake Magadi), male and female W. jocquei sp. nov. (Comoro Islands, Aldabra, Madagascar and Mauritius) and female W. russellsmithi sp. nov. (Mauritius) are described. Pardosa oncka Lawrence, 1927, widely distributed in Africa and redescribed by Kronestedt in 1987, is formally transferred to the genus Wadicosa and new records given.
131
Based on intensive collecting from various sites in Sweden, the genus Dasyhelea Kieffer, 1911 was reviewed and the number of species now known from the country increased from five to twenty. Among the new species recorded there are two species described as new to science, D. dominiakae sp. nov. and D. gothlandica sp. nov., both in the subgenus Dicryptoscena Enderlein, 1936. The following subgenera are now documented from Sweden: Dasyhelea, Dicryptoscena, Pseudoculicoides Malloch, 1915, Prokempia Kieffer, 1913 and Sebessia Remm, 1979, the two latter subgenera being reported for the first time.

129
Based on newly collected material from the Kavieng Lagoon Biodiversity Survey, we describe a new species of cone snail, Conus hughmorrisoni sp. nov., from the vicinity of Kavieng, New Ireland, Papua New Guinea. It closely resembles the New Caledonian C. exiguus and the Philippine C. hanshassi, but differs from these species by having more numerous shoulder tubercles, by the shell’s sculpturing and details of the color pattern. We also sequenced a fragment of the mitochondrial COI gene of five specimens collected alive. All possessed very similar sequences (genetic distances < 0.3%), different from all the COI sequences of cone snails available in GenBank (genetic distances > 10%).
128
The species group effusus of the genus Pyrops Spinola, 1839 is reviewed and the nomenclatural history of the genus Pyrops is briefly summarized. One new species from eastern Borneo, Pyrops synavei sp. nov., is described. P. gunjii (Satô & Nagai, 1994) stat. nov. is proposed as a valid species instead of a subspecies of P. whiteheadi (Distant, 1889). P. maquilinganus (Baker, 1925) is removed from the effusus group and placed back into the candelaria group. P. cyanirostris (Guérin-Méneville, 1845) is removed from the group and not attributed to any of the currently defined species groups. An illustrated key to the species of the group with the addition of P. intricatus (Walker, 1857) and a distribution map are given. The effusus group is restricted to Borneo and adjacent Laut Island and presently contains 4 species: P. effusus (Distant, 1891), P. gunjii (Satô & Nagai, 1994) stat.nov., P. synavei sp. nov. and P. whiteheadi (Distant, 1889). Trophobiosis observations with the gecko Gehyra mutilata (Wiegmann, 1835) (Reptilia: Squamata: Gekkonidae) and two species of cockroaches (Insecta: Blattodea), one Dorylaea sp. and an unidentified species of Pseudophyllodromiinae, are reported and illustrated for P. whiteheadi; observation with a cockroach, Dorylaea sp., is reported for P. intricatus.
