Three New Species

The Tachytrechus alatus species group is revised. The species group is defined within the genus Tachytrechus on the basis of possession of a strong basiventral bristle on the fore femur and very reduced pulvilli on the midand hindlegs of both sexes. Males also possess a strongly reduced vertical bristle, and a cluster of 2–3 strong bristles on both the fore femur and mid coxa. The T. alatus species group is now known from southern Mexico, Central and South America and comprises eight Neotropical species including three new species: Tachytrechus alatus (Becker), Tachytrechus analis (Parent), Tachytrechus costaricensis Brooks sp. nov., Tachytrechus dios Brooks sp. nov., Tachytrechus giganteus (Brooks), Tachytrechus peruicus Yang & Zhang, Tachytrechus transversus (Van Duzee) and Tachytrechus zumbadoi Brooks sp. nov. A revised key to species is provided, as well as remarks on the phylogeny and zoogeography of the group.

Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.

Three New Species

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

The Agrilus purpurifrons species-group comprising twelve species from the Oriental region is defined and revised. A key to species is provided and complemented with illustrations of habitus and genitalia. Three new species are described: Agrilus cameronius sp. nov. (Malaysia); A. puncak sp. nov. (Indonesia); and A. vendibilis sp. nov. (Indonesia). The following taxonomic changes are proposed: the specific names lacroixi Obenberger, 1936 syn. nov. and chapaensis Descarpentries & Villiers, 1967 syn. nov. are junior synonyms in the synonymy of A. morio Kerremans, 1895; the name rousselatae Baudon, 1968 stat. rev. is removed from the synonymy of A. lacroixi Obenberger, 1936 and revalidated as the specific name of A. rousselatae Baudon, 1968.

Three New Species

The Agrilus cyanescens species-group of jewel beetles is defined to include seven species, three of which are newly described: A. dali Jendek sp. n. (China: Yunnan), A. zhongdian Jendek sp. n. (China: Yunnan) and A. arsenevi Jendek sp. n. (Russia: Primorsky Kray). Three new synonyms are proposed for A. cyanescens (Ratzeburg, 1837) (= italicus Obenberger, 1920 syn. n.; = cockerelli Fisher, 1925 syn. n.; = pooli Théry, 1936 syn. n.). Each member of the group is illustrated and an identification key to species, based on males, is provided.

A revision of the genus Orchestia Leach, 1814 with the reinstatement of O. inaequalipes (K.H. Barnard, 1951), the designation of a neotype for Orchestia gammarellus (Pallas, 1776) and the description of three new species (Crustacea: Amphipoda: Talitridae: Talitrinae)

Three New Species

The amphipod genus Orchestia is revised. It now includes 10 species of which three are new: O. forchuensis sp. nov. from north-eastern North America and Iceland., O. perezi sp. nov. from Chile and O. tabladoi sp. nov. from Argentina. Orchestia inaequalipes (K.H. Barnard 1951) is reinstated. The type species of the genus, O. gammarellus is redescribed based on material from Fountainstown, Ireland and a neotype is established to stabilize the species. The species was originally described from a garden in Leiden, far from the sea. Its true identity is unknown and no type material exists. Orchestia gammarellus (Pallas, 1776) is shown to be a sibling species group with members in both hemispheres of the temperate Atlantic as well along the Pacific coast of South America. A hypothesis for the establishment of the current distribution of Orchestia species is presented that extends back to the Cretaceous.

Neotropical Species

The identity of many Neotropical species of Pseudisobrachium Kieffer, 1904 is currently unreachable, mostly because the available descriptions and illustrations are not sufficiently accurate to allow precise identifications. To help solve the problem, 115 valid species and their junior synonyms were examined. Twelve nomenclatural acts are made, and 110 valid species are recognized for the Neotropical region. Two lectotypes are designated: Pristocera crassicornis Westwood and Pristocera haemorrhoidalis Westwood. Seven new species-group synonyms are proposed: Pseudisobrachium retusum Evans syn. nov. for P. pauxillum Evans; P. cunco Perez syn. nov. for P. erythrocephalum Evans; P. navajo Evans, P. rectangulatum Evans, P. emarginatum Evans and P. foutsi Evans syn. nov. for P. flavinervis Fouts; P. acuminatum Waichert & Azevedo syn. nov. for P. latum Waichert & Azevedo. The following new genus-group synonym is established: Parisobrachium Kieffer syn. nov. for Dissomphalus Ashmead. The following new combination and reinstated name are proposed: Dissomphalus albipes (Kieffer) comb. nov. and nom. rev. from Pseudisobrachium paraguayense Kieffer.

First Time

A survey of the whirligig beetles of the genus Patrus Aubé, 1838 occurring in Thailand belonging to the newly designated Patrus landaisi species group is presented. Three new species are described and illustrated: P. garuda sp. nov., P. nanensis sp. nov. and P. phetchabunensis sp. nov.; with P. apicalis (Régimbart, 1891), P. landaisi (Régimbart, 1892), and P. subapicalis (Ochs, 1930) stat. nov. being recorded for the first time in Thailand. Morphological and molecular analyses, together in an integrative approach, support the elevation of P. subapicalis to species status, instead of being a subspecies of P. apicalis. A diagnosis, illustrations of habitus and diagnostic characters, distribution maps, habitat images and a key to species are provided for all known members of the P. landaisi species group that occur in Thailand. A checklist of species in the group is also given.
