Capalictus, a new subgenus of Lasioglossum Curtis, 1833 (Hymenoptera, Apoidea, Halictidae), endemic to the South African Cape Province, is described. The type species is Halictus mosselinus Cockerell, 1945. Evylaeus (Sellalictus) fynbosensis (Pauly et al., 2008) is a new junior synonym of L. (C.) mosselinum. Three new species are described: Lasioglossum (Capalictus) hantamense sp. nov., L. (C.) tigrinum sp. nov. and L. (C.) timmermanni sp. nov. DNA sequence data from three nuclear genes support morphologically-determined species limits. Capalictus is a basal clade of the Hemihalictus series of Lasioglossum.

Dysponetus is a genus of the family Chrysopetalidae with twelve currently described species. Specimens are fragile and easily damaged or broken during sampling making identification difficult. The most recently described species, Dysponetus joeli Olivier et al., 2012, from the Bay of Biscay and the English Channel, was described from a few small, damaged and poorly preserved specimens. New specimens from the Isles of Scilly, in much better condition, resembled D. joeli except for the absence of ventral cirri on segment 3. Examination of the type material of D. joeli showed it to be identical to these new specimens and highlighted errors in the original description of the species. The present paper corrects the errors and a revised key to species is produced. The differences between D. joeli and the two most similar species, D. bipapillatus Dahlgren, 1996 and D. macroculatus Dahlgren, 1996 are also detailed.

Hortipes gigapophysalis (Araneae, Corinnidae) is a new species described from both sexes from montane forest on Mt Nimba, eastern Guinea. The species is remarkable for its long, whip-shaped retrolateral tibial apophysis (RTA) on the male palp. The structure apparently has an insertable function as the epigyne of the female contains a separate set of ducts starting from a central concavity that is unique in the genus. This duct system is apparently meant to receive the supple RTA. This type of structural arrangement has never previously been found in spiders.

Australia is predicted to have a high number of currently undescribed ostracod taxa. The genus Bennelongia De Deckker & McKenzie, 1981 (Crustacea, Ostracoda) occurs in Australia and New Zealand, and has recently shown potential for high speciosity, after the description of nine new species from Western Australia. Here, we focus on Bennelongia from eastern Australia, with the objectives of exploring likely habitats for undiscovered species, genetically characterising published morphological species and scanning classical species for cryptic diversity. Two traditional (morphological) species are confi rmed to be valid using molecular evidence (B. harpago De Deckker & McKenzie, 1981 and B. pinpi De Deckker, 1981), while three new species are described using both morphological and molecular evidence. Two of the new species belong to the B. barangaroo lineage (B. dedeckkeri sp. nov. and B. mckenziei sp. nov.), while the third is a member of the B. nimala lineage (B. regina sp. nov.). Another species was found to be genetically distinct, but is not formally described here owing to a lack of distinguishing morphological features from the existing species B. cuensis Martens et al., 2012. Trends in diversity and radiation of the genus are discussed, as well as implications these results have for the conservation of temporary pool microfauna and our understanding of Bennelongia’s evolutionary origin.

The present study describes five new free-living nematode species and provides three new species records of the family Comesomatidae (genera Cervonema Wieser, 1954, Dorylaimopsis Ditlevsen, 1918, Hopperia Vitiello, 1969, and Kenyanema Muthumbi et al., 1997) from the continental margin of New Zealand, Southwest Pacific. Dichotomous identification keys are provided for all known species of Dorylaimopsis and Hopperia. Cervonema shiae Chen & Vincx, 2000 is recorded for the first time outside the type locality (Beagle Channel, Chile). C. kaikouraensis sp. nov. is characterised by amphideal fovea with 5.5 turns situated at 1.7 head diameter from anterior end, jointed outer labial setae, equal in length to cephalic setae, sperm dimorphism, and 5-6 small pre-cloacal supplements. C. multispira sp. nov. is characterised by amphideal fovea with 8.0-8.5 turns situated at 2.6-4.0 head diameter from anterior end, cephalic setae 2-3 μm long, slightly shorter than outer labial setae, presence of six uninucleated cells in males (potentially pseudocoelomocytes or supplementary excretory cells), 5 small pre-cloacal supplements, and strongly cuticularised, arcuate spicules with capitulum. C. proberti sp. nov. is characterised by amphideal fovea with 5 turns and located at < 1 head diameter from anterior end, cephalic setae 1.6-2.0 times longer than outer labial setae, and 8 small pre-cloacal supplements. Dorylaimopsis nodderi sp. nov. is characterised by cuticle with lateral differentiation consisting of three longitudinal rows of larger dots in the pharyngeal and caudal regions, two rows of larger dots in middle region of body, and spicules with rounded ventral projection at one third of spicule length from distal end, giving appearance of a joint. Hopperia ancora sp. nov. is characterised by short conical cephalic setae, spicules with hook-like projection at distal end, gubernaculum with bent apophyses, and 11-13 pre-cloacal supplements. H. beaglense Chen & Vincx, 1998 is recorded from Kaikoura Canyon, the fi rst record of this species outside the type locality (Beagle Channel, Chile). Kenyanema monorchis Muthumbi et al., 1997 is also recorded for the first time outside the type locality (Indian Ocean).

This study deals with taxonomic problems of the semi-subterranean crangonyctid amphipod Synurella ambulans (F. Müller, 1846), well-known from various freshwater habitats in Europe. The taxonomy of the species S. ambulans and the generic diagnosis for the genus Synurella are revised. A new synonymy is proposed: Synurella ambulans (F. Müller, 1846) = Synurella ambulans meschtscherica Borutzky, 1929, syn. nov. The affinity with the related groups, distribution and ecology of the species are examined.

New genera and problematic species in African Lithosiinae (Lepidoptera, Arctiidae, Lymantriidae)
(2012)
This paper deals with some problematic species in the subfamily Lithosiinae. Two new monospecific genera are proposed: Parafrasura gen. nov. and Palaeugoa gen. nov. The former presents the following autapomorphies: tegumen strong and large; uncus long and slightly claviform; typical scaphium-gnathos complex. The latter presents as autapomorphies the disposition of the bands of the wings pattern, and the male genitalia shape. Asura naumanni Kühne, 2005 is considered incertae sedis within Lithosiinae and Asura phaeosticta Kiriakoff, 1958 is transferred to Euproctis Hübner, [1819] (Lymantriidae) (comb. nov.).

An account of the taxonomic position of the genus Bracon Fabricius, 1804 is presented. In his monograph Wesmael (1838: 7-58) made a survey of 48 nominal species of Bracon occurring in Belgium. Out of the 48 species thirty-seven were described by Wesmael himself as new species, eleven more species had previously been described by Fabricius (three species), Nees (seven species) and Spinola (one species). The Bracon material studied by Wesmael is deposited in the Royal Belgian Institute of Natural Sciences, Brussels. Type (holo-, lecto-, paralectotype) designations are made for Wesmael’s species and neotype designations for Nees sensu Wesmael’s species. Redescriptions, comments on distributions and their taxonomic positions are presented. Palpibracon subgen. nov. is established (type species Bracon delibator Haliday, 1833) for fi ve Bracon species with long maxillary palpi in the Holarctic (four species) and Ethiopian Region (one species). The following fifteen Bracon species names proved to be junior synonyms (valid names in italics): B. dichromus Wesmael, 1838 = B. carpaticus Niezabitowski, 1910 syn. nov.; B. erraticus Wesmael, 1838 = B. bellicosus Papp, 1971 syn. nov., = B. exarator Marshall, 1885 syn. nov., = B. praetermissus Marshall, 1885 syn. nov., B. vectensis Marshall, 1885 syn. nov.; B. fuscicornis Wesmael, 1838 = B. levicarinatus Niezabitowski, 1910 syn. nov.; B. immutator Nees, 1834 = B. breviusculus Wesmael, 1838 syn. nov.; B. intercessor Nees, 1834 = B. laetus Wesmael, 1838 syn. nov.; B. larvicida Wesmael, 1838 = B. crassiusculus Szépligeti, 1901 syn. nov.; B. longicollis Wesmael, 1838 = B. subcylindricus Wesmael, 1838 syn. nov.; B. megapterus Wesmael, 1838 = B. biimpressus Telenga, 1936 syn. nov.; B. nigratus Wesmael, 1838 = B. orbicularis Niezabitowski, 1910 syn. nov.; B. osculator Nees, 1811 = B. coniferarum Fahringer, 1927 (Schmiedeknecht in litt.) syn. nov.; B. picticornis Wesmael, 1838 = B. vitripennis Ratzeburg, 1852 syn. nov.; B. titubatus Wesmael, 1838 = B. fuscipennis Wesmael, 1838 syn. nov. The species Bracon (Lucobracon) turolus Papp, 1984 is revalidated (suppressed under the name B. (Glabrobracon) nigriventris Wesmael, 1838 by Tobias & Belokobylskij 2000: 162). A historic discussion of the subgeneric division of the Bracon species is given.

During verifications of museum material for the Catalogue of the Palaearctic Coleoptera, the type specimen of Hylobius huguenini Reitter, 1891 conserved in the Hungarian National Museum was examined. The type specimen had been found by Gustav Huguenin in the Emmental region in Switzerland. The species was never found again and remained therefore mysterious. After the examination of the type specimen, it became clear that Hylobius huguenini belongs to the American genus Heilipodus Kuschel, 1955 (comb. nov.), and there it ranks as a good species next to Heilipodus goeldii sp. nov., described here, and H. polyspilus (Pascoe, 1889), both from Brazil. The type specimens of Heilipodus goeldii sp. nov. were found in the Emil August Göldi-collection in the Natural History Museum of the Burgergemeinde Bern.

26 samples were processed for a taxonomic study of ostracods from the Upper Permian (Changhsingian) - Lower Triassic (Griesbachian) interval of the Dajiang section, Guizhou Province, South China. 112 species belonging to 27 genera are recognized. Five new species are described: Acratia candyae sp. nov, Bairdia adelineae sp. nov., Bairdia? huberti sp. nov., Bairdia jeromei sp. nov., Orthobairdia jeanlouisi sp. nov. The unexpected survival faunas associated with microbial formations in the aftermath of the end-Permian extinction are documented for the first time. Ostracod biodiversity variations and palaeo-environmental modifications associated with microbial growth through the Permian-Triassic boundary (PTB) are discussed.
18
Sponges belonging to the genera Amphilectus Vosmaer, Esperiopsis Carter and Ulosa de Laubenfels of the family Esperiopsidae were collected during 1986 and 1988 expeditions of the Netherlands Centre for Biodiversity Naturalis (at that time the National Museum of Natural History at Leiden and the Zoological Museum of Amsterdam) in waters off the coasts of Mauritania and the Cape Verde Islands. Four new species, Amphilectus utriculus sp. nov., Amphilectus strepsichelifer sp. nov., Esperiopsis cimensis sp. nov., Ulosa capblancensis sp. nov., and two already known species, Amphilectus cf. fucorum (Esper) and Ulosa stuposa (Esper) are described and discussed.
17
A revision of the known African species of Psammoecus is given, including redescriptions and illustrations of diagnostic characters. Extensive material from the Musée royal de l’Afrique centrale (Tervuren) is studied. Two new species are described: Psammoecus leleupi sp. nov., and Ps. luchti sp. nov. Four specific names are synonymized: Psammoecus excellens Grouvelle, 1908 = Ps. trimaculatus Motschulsky, 1858; Ps. alluaudi Grouvelle, 1912 = Ps. trimaculatus Motschulsky, 1858; Ps. longulus Grouvelle, 1878 = Ps. longicornis Schaufuss, 1872; Ps. nitescens Grouvelle, 1914 = Ps. laetulus Grouvelle, 1914. A key to the African species is provided.
16
Three species of the genus Prorops Waterson, 1923 occur in Madagascar. Prorops nasuta Waterson, 1923 is recorded for the first time from Madagascar and two new species are described and illustrated: P. sparsa sp. nov. and P. impotens sp. nov., both based on the morphology of males and females. A brief discussion of the status of the genus, illustrations, and a key to Madagascan species of Prorops are provided.
15
Dolichoiulus typhlocanaria sp. nov., D. oromii sp. nov. and D. longunguis sp. nov. are described from caves and the mesovoid shallow stratum (MSS) on Gran Canaria. The genus Anagaiulus Enghoff, 1992 is synonymized under Dolichoiulus Verhoeff, 1900, resulting in Dolichoiulus blancatypa (Enghoff, 1992) comb nov.

Three new species of Eupetersia Blüthgen, 1928 (Hymenoptera, Halictidae) from the Oriental Region
(2012)
Three new species, Eupetersia (Nesoeupetersia) singaporensis sp. nov., collected in a mangrove swamp in Singapore, and Eupetersia (Nesoeupetersia) sabahensis sp. nov., collected in the mountains of Sabah, Borneo, and Eupetersia (Nesoeupetersia) yanegai sp. nov., collected in Thailand, are described. This genus is more diversified in the sub-Saharan region, including Madagascar. The only other Oriental species, E. nathani (Baker, 1974), was described from India and is diagnosed and re-illustrated here.
13
The canaliculatus species group of Stenus (Nestus) is redefined. Four new Palaearctic species of the group are described and illustrated: S. (N.) alopex sp. nov. from the Putorana Highland and Taymyr Peninsula, Russia; S. (N.) canalis sp. nov. from SE Siberia and the Russian Far East; S. (N.) canosus sp. nov. from the Narat Mt Ridge, Chinese Tien Shan; S. (N.) delitor sp. nov. from C & SE Siberia. New distributional data as well as brief analyses of old records for fourteen species described earlier are provided from both Palaearctic and Nearctic material. S. (N.) milleporus Casey, 1884 (= sectilifer Casey, 1884) is revalidated as a species propria. S. (N.) sphaerops Casey, 1884 is redescribed; its aedeagus is figured for the fi rst time; the aedeagus of S. (N.) caseyi Puthz, 1972 as well as aedeagi of eight previously described Palaearctic species are illustrated anew. A key for the identification of all the known Palaearctic species of the group is given. A morphology and ecology based analysis of the main evolutionary trends within the group is provided. A lectotype is designated for S. (N.) melanopus Marsham, 1802; its Siberian and NE European records are supposed to be erroneous; the monotypic melanopus species group is erected.
12
The type species of Axinodon ellipticus Verrill & Bush, 1898 and Kellia symmetros Jeffreys, 1876 are re-described. It is concluded that the two species are not conspecific and that K. symmetros cannot be placed in the genus Axinodon. The family affinity of Axinodon is not resolved, although it is probable that this genus belongs to the Thyasiridae. Kellia symmetros is the type species of Kelliola and is placed in the Montacutidae. Kelliola symmetros is most probably associated with the echinoid Aeropsis rostrata and is not the species previously recorded from North Atlantic Pourtalesia echinoids under the name of Axinodon symmetros. This commensal associated with the North Atlantic Pourtalesia is here described as new and placed in the new genus as Syssitomya pourtalesiana gen. nov. sp. nov., Syssitomya gen. nov. differs from all other genera in the Montacutidae by having laminar gill filaments modified for harbouring symbiotic bacteria and it is thus assumed to be chemosymbiotic. A montacutid associated with the hadal Pourtalesia heptneri is described as Ptilomyax hadalis gen. nov. sp. nov.
11
New species Campsicnemus flavissimus sp. nov., C. meridionalis sp. nov., and C. sanctaehelenae sp. nov. are described from St. Helena. A review and key to seven Campsicnemus species inhabiting Azores, Canary Is., Madeira and St. Helena are provided. A new status (as subspecies of C. armatus Zetterstedt, 1849) for C. caffer Curran, 1926 stat. nov. is proposed.

No Name, No Game
(2012)
In an interesting contribution Joppa et al. (2011) revisit some aspects of the taxonomic impediment (Evenhuis 2007; http://www.cbd.int/gti/) and come to the conclusion that, contrary to the generally accepted idea, both the rates of species description and the number of taxonomists have increased exponentially since the 1950’s. Joppa et al. (2011) also note a marked decline in the number of species described per taxonomist which they attribute to the difficulty of finding new species in an ever declining ‘missing species pool’. Therefore, their results might be interpreted that today’s taxonomic workforce is sufficient to describe the remaining (shallow) ‘pool of missing species’. In this contribution, we question if this is indeed the case and propose a solution for speeding up taxonomic descriptions.

We describe a tiny new frog species of the genus Platypelis (Anura: Microhylidae: Cophylinae) from Marojejy National Park, northeastern Madagascar. Platypelis ravus sp. nov. differs from all other known Platypelis and Cophyla species by its small size (17-19 mm snout-vent length) and a combination of other morphological and bioacoustic characters. The new species seems to be most closely related to P. milloti with which it shares the principal colour pattern, but exhibits a yellow rather than red posterior venter. Uncorrected pairwise sequence divergence in a 16S rRNA gene fragment to all other known species of the genus (except P. cowanii for which no genetic data is available) is greater than 6%. We suggest the inclusion of the new species in the IUCN threat category “Data Deficient”.

The genus Bennelongia De Deckker & McKenzie, 1981 is most likely endemic to Australia and New Zealand and, up to now, only two described species in this genus had been reported from Western Australia. Extensive sampling in Western Australia revealed a much higher specifi c diversity. Here, we describe nine new species in three lineages, within the genus Bennelongia: B. cygnus sp. nov. and B. frumenta sp. nov. in the B. cygnus lineage, B. gwelupensis sp. nov., B. coondinerensis sp. nov., B. cuensis sp. nov., B. lata sp. nov. and B. bidgelangensis sp. nov. in the B. australis lineage, and B. strellyensis sp. nov. and B. kimberleyensis sp. nov. (from the Pilbara and Kimberley regions respectively) in the B. pinpi-lineage. For six of the nine species, we were also able to construct molecular phylogenies and to test for cryptic diversity with two different methods based on the evolutionary genetic species concept, namely Birky’s 4 x rule and the GYMC model. These analyses support the specifi c nature of at least four of the fi ve new species in the B. australis lineage and of the two new species in the B. pinpi lineage. We also describe Bennelongiinae n.subfam. to accommodate the genus. With the nine new species described here, the genus Bennelongia now comprises 15 species, but several more await formal description.

A new common deep-sea species of Halirages Boeck, 1871 closely related to H.qvadridentatus G.O. Sars, 1877, H.cainae sp. nov., is described after specimens collected in the Norwegian Sea during the MAREANO 2009-111 cruise. Examination of the syntypes of H. elegans Norman, 1882 demonstrates that Norman's species is a junior synonym of H.qvadridentatus G.O. Sars, 1877 and that the species usually named H.elegans in literature was actually undescribed. The name H.stappersi sp. nov. is proposed for that species. A key to and a checklist of Halirages species is given.
6
Three new species of Helicopsyche Siebold, 1856 are described from Vietnam: Helicopsyche melina sp. nov., Helicopsyche meander sp. nov., and Helicopsyche lamnata sp. nov. All species were described from Melinh Station for Biodiversity in the Me Linh District of Vinh Phuc Province. The species were collected mainly in Malaise traps situated across a small stream surrounded by lowland forest. Some individuals were also collected on light in traps situated at the stream bank.

The fast-running flies (Diptera, Hybotidae, Tachydromiinae) of Singapore and adjacent regions
(2012)
This is the first comprehensive introduction to the flies of the subfamily Tachydromiinae (Hybotidae) of Singapore. The monograph summarizes all publications on the Tachydromiinae of Singapore and includes new data resulting from mass-trapping surveys made in Singapore during the last six years. A few samples from Malaysia (Johor province, Pulau Tioman and Langkawi) have been also included in this study. In Singapore the Tachydromiinae are the most diverse group of Empidoidea (except Dolichopodidae) and currently comprise 85 species belonging to the following nine genera: Platypalpus (1), Tachydromia (1), Chersodromia (6), Pontodromia (1), Drapetis (5), Elaphropeza (60), Crossopalpus (1), Nanodromia (3) and Stilpon (7). All species are diagnosed and illustrated. The following 28 species are described as new for science: Chersodromia bulohensis sp. nov. (Singapore), C. glandula sp. nov. (Singapore, Malaysia), C. malaysiana sp. nov. (Singapore, Malaysia), C. pasir sp. nov. (Malaysia), C. sylvicola sp. nov. (Singapore), C. tiomanensis sp. nov. (Malaysia), Crossopalpus temasek sp. nov. (Singapore), Drapetis bakau sp. nov. (Singapore, Malaysia), D. hutan sp. nov. (Singapore), D. laut sp. nov. (Singapore, Malaysia), D. mandai sp. nov. (Singapore), D. pantai sp. nov. (Singapore, Malaysia), Elaphropeza chanae sp. nov. (Singapore), E. collini sp. nov. (Singapore), E. gohae sp. nov. (Singapore), E. kranjiensis sp. nov. (Singapore), E. lowi sp. nov. (Singapore), E. semakau sp. nov. (Singapore), E. shufenae sp. nov. (Singapore), Nanodromia hutan sp. nov. (Singapore), N. spinulosa sp. nov. (Singapore), Platypalpus singaporensis sp. nov. (Singapore), Pontodromia pantai sp. nov. (Singapore), Stilpon arcuatum sp. nov. (Singapore), S. neesoonensis sp. nov. (Singapore), S. nigripennis sp. nov. (Singapore), S. singaporensis sp. nov. (Singapore), S. weilingae sp. nov. (Singapore). A redescription is given for Crossopalpus exul (Osten-Sacken, 1882) (Taiwan). Males of Elaphropeza feminata Shamshev & Grootaert, 2007 and E. modesta Shamshev & Grootaert, 2007 as well as females of Elaphropeza ubinensis Shamshev & Grootaert, 2007 and Nanodromia narmkroi Grootaert & Shamshev, 2003 are described for the first time. Keys to genera and species, which are generally applicable to the whole of Southeast Asia, are compiled. An analysis of the species ecological preferenda is presented.

Review of Neurepyris Kieffer, 1905 (Hymenoptera, Bethylidae), a new synonym of Pristocera Klug, 1808
(2011)
The genus Neurepyris Kieffer, 1905 is revised. The adult male holotypes N. rufiventer Kieffer, 1913 from Eritrea and N. tagala (Ashmead, 1905) from the Philippines are redescribed and illustrated. Both species are transferred from the subfamily Epyrinae to Pristocerinae because they have the metanotum well developed medially. Neurepyris rufi venter is transferred to Pristocera Klug, 1808 because the hypopygium is deeply divided into two apical lobes, the subdiscoidal and cubital veins do not reach the border of the forewing, the pronotal disc has the anterior region slightly elevate medially, and the stigma is elongate. Neurepyris tagala is transferred to Apenesia Westwood, 1874 because the basal tooth of mandible is not curved inward, the median lobe of clypeus is not depressed near the antennal insertions, and the aedeagus consists of one lamina. The genus Neurepyris is considered a junior synonym of Pristocera because its type species is N. rufiventer.

A new gymnophthalmid lizard of the genus Anadia Gray, 1845 is described from the summit of Abakapá-tepui, Bolívar State, Venezuela, between 2200-2242 m elevation. The new species, Anadia mcdiarmidi sp. nov., is endemic to the Chimantá Massif and seemingly also occurs on Amurí-tepui and Murei-tepui. The new taxon is mainly distinguished from all known congeners by the following combination of characters: body fairly robust, dorsal scales small and quadrangular, middorsal scales 53-57, suboculars large, subequal in size, with sometimes one scale slightly protruding downward between 4th and 5th supralabial, nasal entire, without sub-nostril groove, body uniform beige or greyish to bluish brown in life, devoid of any conspicuous pattern in males, venter immaculate golden grey in life, femoral pores 9-10 on each side in males, preanal pores absent, hemipenis globose, weakly bilobed, bordered by numerous fl ounces (>20) bearing comblike rows of minute weakly mineralized spinules. The presence of a species of Anadia, a primarily Andean genus, on the top of tepuis is of considerable interest to the understanding of the Pantepui biogeography.
