Die Gattung Phormictopuswurde im Jahre 1901 von POCOCK aufgestellt. In seine neue Gattung nahm er als Typusart Mygale cancerides LATREILLE, 1806 von der Insel Hispaniola auf, dazu kam Lasiodora cautus AUSSERER, 1875, eine Art, die ohne Angabe des locus typicus beschrieben worden war. Bisher waren 14 Arten und 2 Unterarten bekannt, von denen 5 aus Südamerika stammen. Die vorliegende Arbeit reduziert die Artenzahl auf 12, wobei 5 neue Arten beschrieben und 4 synonymisiert, 3 zu nomina dubia (Typus verschollen), und 3 "incertae sedis" (in andere Gattungen gehörig) erklärt werden.
A new status (as subgenera of Diostracus Loew, 1861) for Sphyrotarsus Mik, 1874, Lagodechia Negrobov & Tsurikov, 1996 and Ozmena Özdikmen, 2010 stat. nov. is proposed. A new species, Diostracus (Sphyrotarsus) kustovi sp. nov., is described from the Russian Caucasus. The following recombinations (comb. nov.) are also proposed: Diostracus (Sphyrotarsus) argyrostomus (Mik, 1874); D. (S.) caucasicus (Negrobov, 1965); D. (S.) hervebazini (Parent, 1914); D. (S.) hessei (Parent, 1914); D. (S.) hygrophilus (Becker, 1891); D. (S.) leucostomus (Loew, 1861); D. (S.) parenti (Hesse, 1933); D. (Lagodechia) spinulifer Negrobov & Tsurikov, 1988; and D. (Ozmena) stackelbergi (Negrobov, 1965). A key to ten Diostracus species inhabiting the West Palaearctic Region is provided.
Here, I describe four new species of the Neoserica vulpes species group: Neoserica daxue sp. nov., N. mianningana sp. nov., N. myanmarensis sp. nov., and N. yanyuan sp. nov. Genitalia and habitus of the new species are illustrated. Additional records of species from the group are given and the key to species of the Neoserica vulpes species group is updated.
Two new species of the mexicanus group of Vaejovis C.L. Koch are described from the Madrean pine-oak forests of the Sierra Madre Occidental in the state of Durango, Mexico. These species, Vaejovis sierrae sp. nov. and Vaejovis mcwesti sp. nov., are distinguished from each other and the only other species of the mexicanus group known from this mountain range, Vaejovis montanus Graham and Bryson, by morphometrics, carinal development of the pedipalps, granulation of the metasoma, and body size. A key to the species of the mexicanus group from
the Sierra Madre Occidental is provided.
Two new species of Aulonothroscus Horn are described from The Bahamas and a third species is newly reported. Aulonothroscus inawa new species is described from Great Inagua and Aulonothroscus sibateo new species is described from Eleuthera. Aulonothroscus convergens (Horn) is reported from Andros, providing an island and new country record. These are the fi rst Aulonothroscus identifi ed to species from the Lucayan Archipelago and from a West Indies locality other than Guadeloupe. A key to the species of Bahamian Aulonothroscus is provided.
Two species of Xorides Latreille, 1809 are reported parasitizing wood-boring insects in trunks and relatively larger twigs of Juglans mandshurica Maxim. in Kuandian Manzu Autonomous County, Liaoning, in the Palaearctic part of China. Two new species are described: X. juglanse Sheng, Broad & Sun sp. nov. and X. kuandianense Sheng, Broad & Sun sp. nov. One species, X. sapporensis (Uchida, 1928), was associated with wood-borers in J. mandshurica Maxim. for the first time. A key to the 46 species of Xorides Latreille known from China is provided.
Two new species, Camponotus sholensis sp. nov. and Camponotus meghalayaensis sp. nov. are described from India and redescriptions of four species (C. habereri Forel, 1911, C. keihitoi Forel, 1913, C. quadrinotatus Forel, 1886 and C. simoni Emery, 1893) new to India are provided. We also recorded and described an unidentified form ‘Camponotus sp. 101’ that does not correspond to any species already known in India. An identification key supplemented with digital images of the known species of the genus is also provided.
Two new species of shrubs in the genus Lasianthus Jack (Rubiaceae), L. naikii V.S.Dang & Vuong sp. nov. and L. sonlangensis V.S.Dang, Vuong & Quan sp. nov. from Kon Chu Rang Nature Reserve of Gia Lai Province in southern Vietnam, are described and illustrated. The similarities and differences of two new species with the morphologically closest allies are presented. Descriptions, illustrations, colour plates and vernacular names are provided.
Two new species of Grandidierella Coutière, 1904 from Singapore waters are described based on specimens collected during the Comprehensive Marine Biodiversity Survey (CMBS) between 2010–2015. Grandidierella pawaiensis sp. nov. differs from the rest in the genus by a combination of characters; (1) gnathopod 1 carpus proximoventral corner with apically acute process, (2) inner face of carpus of gnathopod 1 proximoventral corner with curved process, (3) proximal margin of dactylus of gnathopod 1 male with excavation, and (4) gnathopod 2 basis anterior margin crenulate. Grandidierella sungeicina sp. nov. on the other hand, is distinguishable from other related species of Grandidierella found in the tropical region by its paired mid-dorsal projections on pereonites 2 to 5, 1 ventrodistal triangular projection on pereonite 4, and gnathopod 2 ischium with 1 large trapezoid projection.
Two new species of damselflies are described from central Halmahera in North Maluku Province, Indonesia. They are Drepanosticta pararudicula sp. nov. (Holotype MZB. ODON. 19257) and Nososticta halmahera sp. nov. (Holotype MZB. ODON. 19265). The two species are most similar to the Moluccan taxa D. rudicula and N. moluccensis respectively and their descriptions bring the total number of Drepanosticta species known from Halmahera to five and of Nososticta to two.
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.
Two new Cordulegaster species are described and illustrated by drawings, photographs and SEM images. The first one, C. plagionyx sp. nov., was discovered in NW Azerbaijan in a low-mountain forest landscape; the second, C. nachitschevanica sp. nov., occurs in the subalpine zone of Nakhichevan AR, south of the main territory of Azerbaijan. Both new taxa look generally similar to C. insignis Schneider, 1845; however, each of them reveals unique features and distinctive combinations of characters that set them apart from other species of the genus. Both new species exhibits new types of sex dimorphism previously unknown in Cordulegaster. Some traits related to the structure of male appendages and important details of colouration prevent both C. plagionyx sp. nov. and C. nachitschevanica sp. nov., from being reliably classified under any of two widely accepted groups of species within the genus Cordulegaster: the boltonii-group and the bidentata-group.
Two new species of the family Selachinematidae Cobb, 1915 from an intertidal sandy flat in the East China Sea are described. Both species are distinct rapacious nematodes, preying on other nematodes. Gammanema magnum sp. nov. is characterized by its leaf-like labial setae, large loop-shaped amphideal fovea in the male and small spiral ones in the female, an anterior buccal cavity reinforced by 12 rhabdia, each rhabdion with about six denticles, and two unequally long spicules. Gammanema magnum sp. nov. is a striking species, exhibiting extreme sexual dimorphism in the amphideal fovea, but lacking a gubernaculum or precloacal supplements, all features by which it can be differentiated from congeneric species. Synonchium caudatubatum sp. nov. is characterized by a posterior buccal cavity, with three mandibles each with a large tooth flanked by three smaller teeth on both sides, a transverse oval-shaped multispiral amphideal fovea, and a bluntly rounded tail with a protuberant caudal duct. Synonchium caudatubatum sp. nov. is unique in the genus in having a protuberant caudal duct in the tail end. Furthermore, it differs from its congeners by its mandibles, which have seven teeth each. Synonchium caudatubatum sp. nov. lacks a gubernaculum and a precloacal supplement, both features present in congeners except S. depressum Gerlach, 1954.
We describe two new frog species of the genus Guibemantis Dubois, 1992 (Mantellidae) from northern Madagascar. Both species are placed in the subgenus Pandanusicola Glaw & Vences, 1994 and, like most of their relatives, appear to only inhabit the leaf axils of Pandanus plants. Guibemantis albomaculatus sp. nov. is distinguished from other closely related species by light colored dorsolateral stripes and abundant small white spots found on its flanks and limbs. Guibemantis woosteri sp. nov. also has light-colored dorsolateral stripes and small white spots, but differs by having strongly banded forelimbs and a reddish coloration around the eye orbits. Mitochondrial DNA sequences corroborate the identity of these two new species, which appear to be regional endemics in northern and north-eastern Madagascar, respectively. These descriptions bring the species count in Pandanusicola to thirteen.
This paper is part of a project of studying benthic diatom biodiversity on marine coastal regions of Sweden with focus on rare and less known species. Two new species of Cocconeis Ehrenb. are described from Vrångö, a small island in the west coast of Sweden. Both species were found as epiphytic on the green alga Ulva intestinalis L. Cocconeis magnoareolata Al-Handal, Riaux-Gob., R.Jahn & A.K.Wulff sp. nov. is a small species not exceeding 9 μm in length and characterized by having large subquadrangular areolae on the sternum valve. Cocconeis vrangoensis Al-Handal & Riaux-Gob. sp. nov. appears similar to some taxa of the 'Cocconeis scutellum complex', but differs by its stria density on both valves and variable features of the areola and valvocopula ultrastructure. Detailed descriptions based on light and electron microscopy examination, a comparison with closely related taxa, as well as a description of the habitat of both species are here presented.
Two new genera, Skelleyus Opitz and Divulgoatus Opitz (Coleoptera: Cleridae: Enopliinae), show unusual antennal development. Funicular antennomeres become shorter as they approach an extensive capitulum. This study involves three taxa, Skelleyus leavengoodi Opitz, new species, Divulgoatus kelleri Opitz, new species, and Divulgoatus discrepans (Gorham).

Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.
Two new species of Elaphropeza Macquart, 1827 are described from the northeast coast of Bali (Indonesia): Elaphropeza triseta sp. nov. belonging to the ephippiata-group and E. balinensis sp. nov. belonging to the biuncinata-group. A COI Neighbour-Joining tree is given for the Southeast Asian Elaphropeza species showing large genetic distances between the species. The morphological characterisation of the ephippiata-group and the biuncinata-group sensu Shamshev & Grootaert 2007 is confirmed.

Three species of false click beetles (Coleoptera: Eucnemidae) are added to the Nearctic fauna. One new species, Isorhipis bicolor, is described from a small series collected in Florida, U.S.A. Eighteen specimens collected from Georgia were identified as Dyscharachthis amplicollis (Fleutiaux), new U.S.A. records for a species previously taken from Japan and Southeast Asia. Examination of a series of eucnemids collected by Kyle Schnepp in Florida allowed me to revisit the Deltometopus fauna in eastern North America. Antennal structures present in a series of male specimens in the loan and past examined specimens are definitive enough to resurrect Deltometopus ereptus Bonvouloir, status restored, from synonymy with Deltometopus amoenicornis (Say). Species identification keys are provided for Deltometopus Bonvouloir and Isorhipis Boisduval and Lacordaire in the Nearctic region. Diagnostic differences are briefly noted for each of the three newly added species found in the United States. Images of three species and the related D. amoenicornis are provided.

Psyllids are an economically important group of insects. Several species are serious emerging pests with regulatory significance. About 20 adventive species have been discovered in Florida in the past 20 years, including several pests. Additionally, five species new to science have been found. We provide an annotated checklist of Florida species with taxonomic information and identification tools, including keys to Florida genera and known species. Seventy species of Psylloidea currently are reported from Florida. Forty-one are native to Florida, with 12 endemic to the state. Twenty are adventive, the majority being from the Neotropics. One was introduced deliberately for biological control, seven represent temporary populations (eradicated, reared in quarantine), and one is a dubious record. Craspedolepta euthamiae Burckhardt and Halbert, new species, Katacephala wineriterae Burckhardt and Halbert, new species, Pseudophacopteron gumbolimbo Burckhardt and Halbert, new species, Nothotrioza longipedis Burckhardt and Halbert, new species, and Trioza myresae Burckhardt and Halbert, new species are described from Florida and are native endemic species.

Twenty-one species of Mysidae were sampled by three ANDEEP expeditions to the Southern Ocean with epibenthic sledges dragged over the deep-sea floor in the realm of 58–71° S and 00–65° W, depth 774–5190 m. Previously known ranges are significantly extended southward for four species and to greater depth in the same four species plus two other species. Supplementary descriptions are given for Amblyops tattersalli and Dactylamblyops murrayi, and a first description of a (subadult) male for Thalassomysis tattersalli. The definitions of the genera Amphiakrops gen. nov., Chelamblyops gen. nov., Desmocornea gen. nov. and Schizurakrops gen. nov. are mainly based on the structure of the eyes as well as of the antennal peduncle, chelate second thoracic endopod and telson. These structures are also important for the descriptions of Amblyops arianii sp. nov., A. bipapillatus sp. nov., Amblyopsoides fenestragothica sp. nov., A. lepidophthalma sp. nov., Amphiakrops brandtae gen. et sp. nov., Dactylamblyops benthophilus sp. nov., Desmocornea subchelata gen. et sp. nov., Paramblyops petrescui sp. nov., Schizurakrops meesi gen. et sp. nov., Scolamblyops muehlenhardtae sp. nov., Stellamblyops doryphorus sp. nov. and Mysidella antarctica sp. nov. Six previously described taxa are recombined as Amblyopsoides laticauda comb. nov., Amphiakrops bidigitatus comb. nov., A. japonicus comb. nov., Chelamblyops globorostris comb. nov., Meierythrops tattersalli comb. nov. and M. triangulatus comb. nov. One species is revised back to the initial combination as Dactylamblyops japonicus. All except one (Mysidella antarctica sp. nov.) newly described (12), newly recombined (6) or back-combined (1) species belong to the Erythropinae. Keys to the resulting 61 genera and 263 species of Erythropinae and 18 species of Mysidellinae are given at the world-wide scale. Ocular papillae with a terminal pore (sensory pore organ) are recorded in nine ANDEEP species. The organ of Bellonci is identified on the reduced eyes in 16 species, among which D. subchelata gen. et sp. nov. has many ommatidia arranged in a self-contained ribbon which shows a banded rhabdom only in non-adults. Reduction of visual elements together with shrinking of ocular papillae during ontogenetic development suggest that non-adults of D. subchelata and T. tattersalli stay in the photic zone for feeding and growth and then descend only once during their lifetime to the abyss for reproduction.
The eight species in the genus Tomarus Erichson (Coleoptera: Scarabaeidae) in Argentina, Chile, and Uruguay are reviewed. Tomarus roigjunenti new species and Tomarus spinipenis new species are described from Argentina.

Five species of the terrestrial diatom genus Luticola D.G.Mann were found during a taxonomic survey of two small volcanic islands, Ile Amsterdam and Ile Saint-Paul (Southern Indian Ocean). Apart from the two already known Luticola species L. beyensii Van de Vijver et al. and L. subcrozetensis Van de Vijver et al., two new species are described: L. ivetana Chattová & Van de Vijver sp. nov. and L. vancampiana Chattová & Van de Vijver sp. nov. Finally, one, up to now unknown, Luticola species is briefly discussed and illustrated. Detailed morphological descriptions of these taxa are provided based on both light and scanning electron microscopy observations. Morphological features of the new species are compared to morphologically similar taxa, and notes on their ecology and biogeography are added.
The genus Erlandia (Cerambycinae: Erlandiini) was described by Aurivillius in 1904, containing a single species, Erlandia inopinata, distributed in Bolivia, Argentina, and Paraguay. Anew species, E. megacephala, from Argentina is described, and illustrated here. A key and distribution map of both species are provided, with a generic diagnosis using characters of both species.
Based on morphological and molecular evidence, two new species of Silene are recognized and described here, S. penduliflora F.Jafari, Keshavarzi & Doostm. sp. nov. and S. thyrsiantha F.Jafari, Mirtadz. & Keshavarzi sp. nov. The newly discovered species are distributed in the central and southeastern parts of Iran, growing in rocky habitats. Relationships among these species and their close relatives are demonstrated using nrDNA ITS and cpDNA rps16 phylogenies. Silene ghahremaninejadii, S. parrowiana, and S. shahrudensis form a clade with these new species. A key to S. penduliflora and S. thyrsiantha and their close relatives is provided.
We provide a floristic account for the Begoniaceae of Peru. The family is represented in Peru by 76 species, which are all members of the genus Begonia and represent eighteen sections.

Twenty-six names are newly synonymised including fifteen previously accepted species, and we designate eighty-three lectotypes, four neotypes, and four epitypes.
The Iranian species of the genus Anomalon Panzer, 1804 (Hymenoptera: Ichneumonidae: Anomaloninae) are reviewed. Four species, Anomalon amseli (Hedwig, 1961), A. chinense (Kokujev, 1915), A. cruentatum (Geoffroy, 1785) and A. narinae Zardouei & Rakhshani sp. nov., are found to occur in Iran. The female of A. amseli is described for the first time. Anomalon chinense is a new record for Iran. A key to the known Anomalon species of Iran is provided.
The first Oriental species of the genus Trichopsomyia Williston, 1888, Trichopsomyia pilosa sp. nov. (Java), has been discovered and is now described. This Oriental species of Trichopsomyia has several characters strongly differing from the other species within this genus. It is hypothesized that it forms a separate group within Trichopsomyia. One species, Trichopsomyia formiciphila Downes, Skevington & Thompson, 2017, from Australia, is similar to the Oriental species described here, and the group is named after this first described species, hence the formiciphila group. The characters for a future phylogenetic analysis are discussed. The character states of the pilosity of the katepisternum and the shape of the metasternum hitherto used in a phylogenetic analysis of Syrphidae Latreille, 1802 are discussed too.

The Chimarra lehibemavo species-group, new and endemic to Madagascar (Trichoptera, Philopotamidae)
(2017)
The Chimarra lehibemavo group is described to include thirteen new species: Chimarra lehibemavo sp. nov., C. cebegepi sp. nov., C. fenoevo sp. nov., C. forcellinii sp. nov., C. fotobohitra sp. nov., C. gattolliati sp. nov., C. gensonae sp. nov., C. jejyorum sp. nov., C. hamatra sp. nov., C. makiorum sp. nov., C. moramanga sp. nov., C. saha sp. nov. and C. tamara sp. nov. The adults are easily recognizable by their large size, yellow colour and the structure of the male genitalia. The membranous tergum IX and the absence of the mesal lobe of tergum X are observed in other lineages, but the strong asymmetrical deformation of the phallotheca is apomorphic. The group is monophyletic with unknown affinities, but a preliminary phylogenetic placement is suggested following genetic analysis of two specimens. With one exception, the species have restricted geographical distributions in Madagascar and inhabit rivers in eastern pristine rainforests.

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.
From 1995 to 2004 collections for Bruchidae (Coleoptera) were made in La Reserva de la Biósfera Sierra de Huautla, Morelos, Mexico. Specimens were reared from mature seedpods, but also collected by net, malaise trap, and light trap. In total 72 species in 13 genera of Bruchidae were recovered. Of those two new species are here described: Amblycerus montalvoi Romero and Acanthoscelides camerinoi Romero. We record 27 host plants for the bruchids found in the study area.
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.
The previously endemic Australian genus Habritella Girault & Dodd, 1915 is reported for the first time in the Afrotropical region with four new species: H. africana sp. nov., H. mandibulata sp. nov., H. noyesi sp. nov., and H. viridifrons sp. nov. The males of Habritella are described for the first time. A new generic synonymy and combination are also proposed: Ezgia Koçak & Kemal, 2008 syn. nov. and H. stylifera (Bouček, 1988) comb. nov. Habritella is redescribed to accommodate the newly discovered and transferred species. An illustrated key to the Afrotropical species is provided.
Sweat bees in the subgenus Lasioglossum (Dialictus) are one of the most diverse and abundant bee taxa, and a critically important component of bee biodiversity. Yet, the most basic taxonomic knowledge of these bees is lacking in many regions. As a step towards a better understanding of the L. (Dialictus) of the western Nearctic region, a revision of the ‘red-tailed’ L. (Dialictus) species was completed. Thirty-six species were revised, 20 of which are described as new, and two names are treated as junior subjective synonyms. Descriptions, figures, distribution maps, floral hosts, and keys to species for females and males are provided. The following 20 species are described as new: Lasioglossum (Dialictus) arenisaltans sp. nov., L. (D.) argammon sp. nov., L. (D.) austerum sp. nov., L. (D.) cactorum sp. nov., L. (D.) cembrilacus sp. nov., L. (D.) clastipedion sp. nov., L. (D.) clavicorne sp. nov., L. (D.) decorum sp. nov., L. (D.) festinum sp. nov., L. (D.) imbriumbrae sp. nov., L. (D.) julipile sp. nov., L. (D.) lilianae sp. nov., L. (D.) meteorum sp. nov., L. (D.) miltolepoides sp. nov., L. (D.) minckleyi sp. nov., L. (D.) perditum sp. nov., L. (D.) rufornatum sp. nov., L. (D. ) spivakae sp. nov., L. (D.) tessellatosum sp. nov., and L. (D.) torrens sp. nov. Previously unknown males of L. (D.) clematisellum (Cockerell, 1904), L. (D.) droegei Gibbs, 2009, L. (D.) kunzei (Cockerell, 1898), and L. (D.) pallidellum (Ellis, 1914) are described and figured for the first time. Lasioglossum (Dialictus) clarissimum (Ellis, 1914) (= Halictus clarissimus Ellis, 1914) and L. (D.) perexiguum (Sandhouse, 1924) (= Halictus (Chloralictus) perexiguus Sandhouse, 1924) are new subjective junior synonyms of L. mesillense (Cockerell, 1898) (= Halictus nymphalis var. mesillensis Cockerell, 1898). A lectotype specimen is newly designated for L. mesillense, for which the location of the type material has not previously been known. The following five new records for Mexico are reported: L. clematisellum, L. droegei, L. eophilus (Ellis, 1914), L. kunzei, and L. pallidellum.
A new fossil diatom species, Tertiarius minutulus sp. nov., is described from a sediment sequence DEEP-5045-1 of Lake Ohrid. The species is characterized by small valves (3.0–8.0 μm) with a round shape, a marginal area with radially arranged costae and a central uneven area with scattered areolae. Externally, the alveoli are occluded by cribra perforated by irregularly arranged pores. Internally, the alveoli are simple and areolae are occluded with domed cribra. The marginal fultoportulae are situated on costae close to the valve margin, located on every 5th or 7th thick internal costa. One to three fultoportulae are present on the valve face, each surrounded by two to three satellite pores. One rimoportula is present, positioned on a costa at the valve face / mantle junction. The species is compared with morphologically similar taxa and a detailed differential diagnosis is provided. Tertiarius minutulus sp. nov. is known only as a fossil taxon from Lake Ohrid, with a first occurrence during the early stages of lake basin development.
The linyphiid spiders Tenuiphantes zelatus (Zorsch, 1937), T. zibus (Zorsch, 1937), and Centromerus mariannae sp. nov. are diagnosed, described or redescribed and illustrated, including the previously undescribed female of T. zibus. All are common species of the Pacific Northwest of North America but were previously inadequately described (T. zelatus and T. zibus) or illustrated only but not described or named (C. mariannae).
A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
The Quedius mutilatus group, a very poorly known presumably monophyletic complex of wingless, possibly hypogean species confined to the Tien-Shan Mountains, is characterized as such for the first time. Newly available material clarified the identity of Q. mutilatus Eppelsheim, 1888 and Q. kalabi Smetana, 1995, each hitherto known from a handful of non-conspecific and vaguely georeferenced specimens only. Additional material is reported for Q. equus Smetana, 2014 and bionomics for all these four species of the group are summarized.
Neopanorpa van der Weele, 1909 is the second largest genus in Panorpidae, and over 170 Oriental species have been reported hitherto. In this paper, we describe two new species: Neopanorpa luojishana sp. nov. and Neopanorpa xingmini sp. nov. from Southwest China. We also report the first discovery of the male of Neopanorpa ocellaris (Navás, 1908) from Guangxi and Guizhou, China, a species recorded from Sikkim previously. Neopanorpa brevivalvae Chou & Wang, 1988 is synonymized with Neopanorpa lungtaushana Cheng, 1957. In addition, Neopanorpa furcula nom. nov. is proposed for Neopanorpa furcata Zhou, 2005, a junior homonym preoccupied by Neopanorpa furcata (Hardwicke, 1825). The biogeographical implications of some Neopanorpa species are discussed in brief.
Antiochtha is a genus of the family Lecithoceridae characterized by the forewing with veins M2 and M3 coincident, the hindwing with vein M2 absent, and the male genitalia with the valva narrowed from base to apex. The genus comprises 23 species and is mainly distributed in the Oriental Region. In this paper, we describe three new species: Antiochtha erromera sp. nov., A. hainanensis sp. nov. and A. miniscula sp. nov., and propose a new synonym, A. rotunda Zhu & Li, 2009 syn. nov., of A. jianfengensis Zhu & Li, 2009. Antiochtha semialis Park, 2002 is newly recorded in China and its female is described for the first time.
Ninety percent of the Cixiidae of the Macaronesian archipelagos are endemic. Each archipelago has its own endemics reaching a total of 31 taxa. The Madeira archipelago comprises five species: Cixius madeirensis China, 1938, C. verticalis Noualhier, 1897, C. chaoensis China, 1938, Hyalesthes madeires Remane & Hoch, 1986 and H. portonoves Remane & Hoch, 1986. Good knowledge concerning taxonomy, habitat information and distribution are essential for the conservation of the biodiversity of this rich archipelago. However, due to intraspecific variation and incomplete descriptions, misidentifications of Madeira cixiids have been common. In this work, the taxonomy of this family is reviewed and ecological data based on material collected over more than forty years are presented. A new species, Cixius wollastoni sp. nov., is described. A new combination, Tachycixius chaoensis (China, 1938) comb. nov., is proposed, and a new record, Pentastiridius leporinus (Linnaeus, 1761), is reported. Lectotypes are designated for Tachycixius chaoensis and C. verticalis. The genital structures of the latter species are depicted for the first time. All species are diagnosed, described, photographed and illustrated, and an identification key for the family is provided. Thanks to this new information, Madeira together with Tenerife are the two Macaronesian islands with the highest number of endemic species of cixids.
This study reviews the taxonomy of the ant genus Nesomyrmex Wheeler, 1910 in the Afrotropical region. Previous revisionary studies are discussed and four species groups are proposed on the basis of external morphology. The N. angulatus group contains seven species that are widely distributed throughout the whole Afrotropical region, with one species also occurring in the Palaearctic and Malagasy regions. The N. cataulacoides group is monotypic, with one morphologically bizarre species found in Equatorial rain forests. The N. humerosus group is also monotypic and occurs in East Africa. The last and by far most species-rich group is the N. simoni group that contains 17 species, all of which are endemic to South Africa. The four groups are defined for the first time for the region, and an illustrated identification key is provided. Furthermore, the N. angulatus group is more thoroughly reviewed. One new species from Mozambique is described, N. inhaca sp. nov., and species accounts for the other six are provided. Also, an illustrated identification key to the species of the N. angulatus group is presented.
The Chinese members of the genera Leptothorax Mayr, 1855 and Temnothorax Mayr, 1861 are reviewed based on the morphological characters of the worker caste, and 66 species are recognized in China to date.

Taxonomic revision of the genus Arsipoda Erichson, 1842 (Coleoptera, Chrysomelidae) in New Caledonia
(2016)
A taxonomic revision of the New Caledonian species of Arsipoda Erichson, 1842 is provided. This group includes 21 species, of which 14 are new to science: Arsipoda atra sp. nov., A. communis sp. nov., A. doboszi sp. nov., A. elongata sp. nov., A. gomezzuritai sp. nov., A. gressitti sp. nov., A. longifrons sp. nov., A. montana sp. nov., A. paniensis sp. nov., A. povilaensis sp. nov., A. punctata sp. nov., A. rutai sp. nov., A. transversa sp. nov. and A. wanati sp. nov. A key for the identification, with figures of habitus, main diagnostic characters, and genitalia is supplied. The range of host plants for these species is extraordinarily broad, and a significant number of them feed on pollen. Crepicnema Scherer, 1969, close to Arsipoda, is also investigated and maintained as a separate genus, and the following synonymies and combination are proposed: Crepicnema parvula (Jacoby, 1885) comb. nov. = Chaetocnema tenimberensis Jacoby, 1894 syn. nov., = Arsipoda salomonensis Bryant, 1941 syn. nov. The phylogenetic analysis, including also A. bifrons Erichson, 1842 and Crepicnema, confirms some trends in distribution patterns of the endemic New Caledonian fauna, and highlights the necessity of further studies to clarify the relationships between Arsipoda and related genera.
The dung beetles belonging to the genus Deltochilum Eschscholtz, 1822 are widely distributed in the Neotropical region. This genus is divided into eight subgenera, of these, the subgenus Deltohyboma Lane, 1946 is the most diverse, with an estimated 212 species. The most recent revision of Deltohyboma divided the subgenus into 19 species group. Here, taxonomy of the gilli species group is revised. Four new species (D. jocelynae sp. nov., D. nonstriatum sp. nov., D. quasistriatum sp. nov. and D. tenuistriatum sp. nov.) are described, making a total of five species within the species group. Keys for species identification and habitus as well as male genitalia morphology are illustrated.
The gigas species group of the subgenus Canthidium (Neocanthidium) is defi ned and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identifi cation key and comments on the distributions of the species of the gigas group.
Taxonomic revision of North American Eusphalerum Kraatz, 1857 (Coleoptera, Staphylinidae, Omaliinae)
(2014)
The North American species of the genus Eusphalerum Kraatz (Coleoptera, Staphylinidae, Omaliinae) are revised. The taxonomic history, natural history, geographical distribution of the genus, characters, species groups, diversity, and biogeography of North American species are presented. Two main phylogenetic lineages and 13 species groups are provisionally recognized. The following new synonymies are proposed: Eusphalerum farrarae (Hatch, 1944) = E. lawrencei Hatch, 1957; Eusphalerum californicum (Fauvel, 1878) = E. atriventre (Casey, 1894), = E. nigerrimum (Casey, 1894), = E. gilvipenne (Casey, 1894), = E. dichroum (Fall, 1922), = E. bonnelli (Hatch, 1944), = E. lunae Hatch, 1957; Eusphalerum fraternum (Casey, 1894) = E. minskae (Hatch, 1944); Eusphalerum rugulosum (Mäklin, 1853) = E. grayae (Hatch, 1944); Eusphalerum orientale (Bernhauer, 1912) = E. frosti (Bernhauer, 1928). The following lectotypes are designated: E. subangulatum (Casey), E. californicum (Fauvel), E. gilvipenne (Casey), E. diversicolle (Casey), E. convexum (Fauvel), E. fraternum (Casey), E. horni (Fauvel), E. orientale (Bernhauer), E. pothos (Mannerheim), and E. punctatum (Casey). The following new species are described: Eusphalerum pilosum (California); E. klimaszewskii (British Columbia); E. chatzimanolisi (California); E. carolinensis (Kentucky, Missouri, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia); E. caterinoi (California); E. luteipes (California); E. thayeranum (Alberta, British Columbia, Idaho, Indiana (doubtful record), Oregon, Washington); E. margaretae (Tennessee); E. newtoni (British Columbia, Oregon, California); E. parvispiculum (California, Oregon); E. uncinatum (British Columbia, California, Oregon, Washington). Eusphalerum lapponicum (Mannerheim, 1830) is excluded from the North American fauna. The following new combination is proposed: Xylodromus segmentarius (Mäklin, 1852: 322) (ex Omalium), wrongly attributed to Eusphalerum in the literature. Omalium marginatum Say, 1832 is considered a doubtful species, probably not Eusphalerum. A key to the 27 recognized North American Eusphalerum species and a catalog of the species are provided.
The enigmatic millipede assassin bug genus Xenorhyncocoris Miller, 1938 is revised. Previously known species, X. caraboides Miller, 1938, X. princeps Miller, 1949 and X. schoenitzeri Putshkov & Bérenger, 1999, are diagnosed and photographed. A new species, X. attractivus sp. nov., is described based on male and female specimens from northeastern Borneo. The male of Xenorhyncocoris is reported for the first time, revealing the extreme sexual dimorphism present in the genus. The diagnosis of Xenorhyncocoris is extended in order to make it applicable to the new discovery, and a female-based key to species of the genus is updated. Relationships among Xenorhyncocoris and Vilius Stål, 1863, Neozirta Distant, 1919 and Schottus Distant, 1902 are briefly discussed.

The Neotropical D. agenor species group of the subgenus Luederwaldtinia Martínez, 1951 is taxonomically reviewed. After examination of specimens in collections, the D. agenor species group will consist of seventeen species, a leap from the former nine species: D. agenor (Harold, 1869), D. amplicollis (Harold, 1869), D. belus (Harold, 1880), D. centralis (Harold, 1869), D. deyrollei (Harold, 1869), D. sagittarius (Harold, 1869) stat. rev., D. tristis (Luederwaldt, 1923), D. triquetrus (Luederwaldt, 1923), D. validipilosus (Luederwaldt, 1931), D. fornicatus (Luederwaldt, 1931) [transferred to D. lucasi species group and to which D. bosqi (Pereira, 1941) is considered to be a new synonym], D. inachoides (Felsche, 1901) [transferred from the group fisus (Selenocopris)], D. simplicicornis (Luederwaldt, 1935) [transferred from the group fisus (Selenocopris)], D. subaeneus (Castelnau, 1840) [transferred from the D. carbonarius species group], D. rafanunezi sp. nov. from Mato Grosso, D. henripittieri sp. nov. from Venezuela and D. enioi sp. nov. from Guatemala and Costa Rica. This review was based on external morphology and characters of the male genitalia (aedeagus and internal sac). Descriptions of new species and redescriptions were made after examining the type-specimens of the already described species. Lectotype designations, species revalidations, redescriptions and new species descriptions are provided.
The species of Rhyacobates Esaki, 1923 are reviewed. Three new species, R. bui sp. nov. from Guangxi, China and Lạng Sơn, Vietnam, R. elongatus sp. nov. from Hà Tĩnh, Vietnam and R. turgidus sp. nov. from Sichuan and Chongqing, China are described. Supplemental descriptions, diagnoses and new distribution records are provided for the fourteen previously known species, i.e., R. abdominalis Andersen & Chen, 1995, R. anderseni Tran & Yang, 2006, R. angustus Tran & Nguyen, 2016, R. chinensis Hungerford & Matsuda, 1959, R. constrictus Tran & Nguyen, 2016, R. edentatus Andersen & Chen, 1995, R. gongvo Tran & Yang, 2006, R. lundbladi (Hungerford, 1957), R. malaisei Andersen & Chen, 1995, R. recurvus Andersen & Chen, 1995, R. scorpio Andersen & Chen, 1995, R. svenhedini (Lundblad, 1934), R. takahashii Esaki, 1923, and R. zetteli Tran & Nguyen, 2016.

The New World euparine scarab genera Parataenius Balthasar, 1961 and Pseudataenius Brown, 1927 are revised. Ataenius brunneus Schmidt is transferred to the genus Parataenius becoming Parataenius brunneus (Schmidt), new combination. The monospecific genus Ataenioides Petrovitz, 1973, is synonymized with Pseudataenius Brown, 1927, (new synonymy) and the type species, Ataenioides gracilitarsis Petrovitz, is given the new combination Pseudataenius gracilitarsis (Petrovitz). New species of Parataenius are described from southern South America: Parataenius selvae, P. estero, and P. martinezi. Keys for species of both genera are presented and pertinent morphological details are illustrated.
The adult stage of Helioandesia tarregai gen. et sp. nov. (Lepidoptera: Yponomeutoidea: Heliodinidae) is described and illustrated from the arid western slopes of the Andes of northern Chile. The larvae of H. tarregai gen. et sp. nov. feed as leaf skeletonizers on Mirabilis acuta (Reiche) Heimerl (Nyctaginaceae). The mostly gray forewing of H. tarregai gen. et sp. nov., ornamented with strongly bulging metallic spots, resembles that of the representatives of the mainly Nearctic Lithariapteryx Chambers, 1876. However, the latter lacks CuP in the forewing, has a single bristle in the female frenulum, and lacks a well-developed cornutus. Helioandesia gen. nov. clustered as sister to Neoheliodines Hsu, 2004 in a cladistic analysis, although no synapomorphies were found for this cluster, while Lithariapteryx was sister to Helioandesia gen. nov. + Neoheliodines based on two synapomorphies. The genetic distance between a DNA barcode sequence of H. tarregai gen. et sp. nov. and representatives of other genera of Heliodinidae Heinemann, 1877 was 9.0–12.5% (K2P), and a maximum likelihood analysis based on this molecular marker confirmed the placement of H. tarregai gen. et sp. nov. as a member of this micromoth family. This contribution represents the first confirmed record of Heliodinidae for Chile.
A systematic redefinition of the species belonging to the genus Geomyphilus Gordon and Skelley, 2007 (Coleoptera: Scarabaeidae: Aphodiinae) of Mexico and neighboring countries is presented. The new species G. tuzincola of Mexico is described and figured. The new combination Coelotrachelus macgregori (Islas, 1955) is proposed.
The family Plectopylidae is divided into two subfamilies: Sinicolinae subfam. nov. (included extant genera: Gudeodiscus Páll-Gergely, 2013, Endothyrella Zilch, 1959, Halongella Páll-Gergely, 2015, Sicradiscus Páll-Gergely, 2013, Sinicola Gude, 1899) and Plectopylinae Möllendorff, 1898 (included genera: Chersaecia Gude, 1899, Hunyadiscus Páll-Gergely, 2016, Naggsia Páll-Gergely & Muratov, 2016, Plectopylis Benson, 1860). The Eocene fossil Plectopyloides Yen, 1969 is classified into the Sinicolinae. The Plectopylinae are revised mainly based on historical type and non-type material, and the material of the Florida Museum of Natural History, collected in Thailand in the 1980s. The following species-group taxa are described as new: Chersaecia auffenbergi sp. nov., Chersaecia densegyrata sp. nov., Chersaecia mogokensis sp. nov., Chersaecia reversalis sp. nov., Chersaecia scabra sp. nov., Chersaecia shiroiensis subnagaensis subsp. nov., Hunyadiscus tigrina sp. nov., Naggsia oligogyra sp. nov., Plectopylis crassilabris sp. nov., Plectopylis malayana sp. nov. and Plectopylis thompsoni sp. nov. The genus Endoplon Gude, 1899 is treated as a synonym of Chersaecia. Consequently, the two species classified in Endoplon are members of Chersaecia: Chersaecia brachyplecta (Benson, 1863) comb. nov. and Chersaecia smithiana (Gude, 1897) comb. nov. The genus Plectopylis is redefined, and includes only species with fused anterior and posterior lamellae. Thus, the following species are moved from Plectopylis to Chersaecia: Chersaecia feddeni (Blanford, 1865) comb. nov., Chersaecia goniobathmos (Ehrmann, 1922) comb. nov., Chersaecia leucochila (Gude, 1897) comb. nov., Chersaecia magna (Gude, 1897) comb. nov. and Chersaecia woodthorpei (Gude, 1899) comb. nov. Altogether thirteen species and varieties are moved to the synonymy of valid species: Helix (Plectopylis) brachydiscus Godwin-Austen, 1879 syn. nov., Helix (Plectopylis) ponsonbyi Godwin-Austen, 1888 syn. nov., Plectopylis (Chersaecia) kengtungensis Gude, 1914 syn. nov., Plectopylis (Chersaecia) degerbolae Solem, 1966 syn. nov., Plectopylis lissochlamys Gude, 1897 syn. nov., Helix repercussa Gould, 1856 syn. nov., Plectopylis achatina var. obesa Gude, 1898 syn. nov., Plectopylis achatina var. infrafasciata Gude, 1898 syn. nov. Plectopylis achatina var. venusta Gude, 1898 syn. nov., Plectopylis achatina var. castanea Gude, 1898 syn. nov., Plectopylis achatina var. breviplica Gude, 1898 syn. nov., Plectopylis achatina var. repercussoides Gude, 1899 syn. nov., Plectopylis linterae var. fusca Gude, 1898 syn. nov. Plectopylis (Chersaecia) simplex Solem, 1966 is a subspecies of Chersaecia perarcta (Blanford, 1865), whereas Plectopylis muspratti Gude, 1897 is a subspecies of Chersaecia nagaensis (Godwin-Austen, 1875).
Besides the two species at present known belonging to the genus Trichonotuloides Balthasar (T. glyptus (Bates) and T. latecrenatus (Bates)), two new Mexican species, T. alfonsinae and T. hansferyi, are herein described (Coleoptera: Scarabaeidae: Aphodiinae). The complete set of fi gures is supplied for all taxa herein dealt with.
Thirty five Western Hemisphere species of Glaresidae (Coleoptera) are recognized.
