A morphological and genetic study of both newly collected and museum specimens of the east Australian freshwater shrimp genus Australatya indicates two genotypes and three morphotypes are present. One genotype and morphotype were of the known species, Australatya striolata (McCulloch McNeill 1923). The second genotype, comprising two morphotypes, is now described as a new species, Australatya hawkei sp. nov.. All Australian Australatya species and morphotypes currently have allopatric distributions. Australatya striolata is widespread along the south-eastern Australian seaboard, from Genoa River in Victoria to the Sunshine Coast in Queensland. The 'southern' morphotype of Australatya hawkei sp. nov. occurs in north Queensland, from near Mackay to about Cooktown, and its 'northern' morphotype is found on Cape York Peninsula, north from about Coen to the Iron Range, just north of Lockhart River. The once monotypic genus now includes two Australian species, Australatya striolata and A. hawkei sp. nov., and a third, A. obscura, recently described from Japan, Taiwan, and the Philippines.A non-native oligochaete, Bratislavia dadayi (Michaelsen 1905), is recorded from a water body of the cooling system of the Khmelnitsky Nuclear Power Plant (Ukraine). This is the first registration of this species in the central part of the European continent, far from sea and river navigable waterways. The only previous record of B. dadayi in Europe had been from a Belgian estuary. The occurrence in samples taken over several years, and the presence of sexually mature individuals in the Ukrainian population indicate the worm's successful naturalization in the new habitat. In this paper, we analyze the species' morphology and abundance in the Ukrainian population and discuss its ecology, current and potential distribution.Seven loaches of Homatula are distributed in a narrow geographical area between the upper Black River (or Song Da in Vietnam, that is a major tributary of the Red River, including the tributaries Lixian-jiang and Tengtiao-jiang in Yunnan, China) and the upper Salween River drainage (including tributaries of the Nu-jiang and Nanding-he, the latter is a major tributary of the Salween River in Yunnan, China). These seven species are distinguished from other Homatula by the combination of having the body densely-scaled, the lateral line complete, and a short adipose crest along the dorsal midline of the caudal peduncle that does not reach the posterior end of anal-fin base or does not extend beyond the middle of the anal-fin base. Based on a comparison with the described species of the densely-scaled group of Homatula, we can confirm that the specimens collected from the Nu-jiang drainage in western Yunnan are different from known species and are described herein as Homatula anteridorsalis sp. nov., Homatula cryptoclathrata sp. nov., and Homatula nigra sp. nov.A new species, Metatarsonemus caissara Lofego Cavalcante sp. nov., is described based on females and males collected on Eugenia umbelliflora O. Berg. (Myrtaceae) from Atlantic Forest areas of São Paulo State, Brazil. Metatarsonemus Attiah is reinstated as a genus based on apomorphic attributes which are recovered through examination of specimens of the new species herein described, in addition to specimens of M. simplicissimus Attiah and M. megasolenidii Lofego Ochoa. A cladistic analysis tentatively indicates that the Metatarsonemus lineage is sister group to a lineage comprising the genera complex Daidalotarsonemus+Ceratotarsonemus+Excelsotarsonemus in sharing four homoplasious apomorphic attributes. A dichotomous key is provided for identification of the species of this genus described so far.Two new species of the genus Brachyzapus Gauld Dubois are described from South Korea Brachyzapus convergens sp. nov. and B. pyramidalis sp. nov. Four species of this genus are newly recorded from South Korea, with diagnoses provided. A key to species of the Palaearctic region of this genus and illustrations of their external characters are provided.We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachyproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters body size larger (SVL of adult males 74.2-83.3 mm; SVL of adult female 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.Species of North American Cybaeus L. Koch (Araneae Dictynoidea Cybaeidae) are common moist-forest spiders classified in Holarctic and Californian clades. Here we review the adenes species group of the Californian clade. We recognize nine species Cybaeus adenes Chamberlin Ivie, C. amicus Chamberlin Ivie, C. auburn Bennett spec. BI-3812 in vivo nov., C. grizzlyi Schenkel, C. pearcei Bennett spec. nov., C. reducens Chamberlin Ivie, C. sanbruno Bennett, C. schusteri Bennett spec. nov., and C. torosus Bennett spec. nov. The species of the adenes group have extremely restricted ranges in west central California from Sonoma and Napa Counties south to northern Monterey County and in east central California from Placer and El Dorado Counties. Descriptions, illustrations, range maps, and an identification key are provided for all species.We review Sisyromyia White (Bombyliidae, Bombyliinae), a remarkable Australian endemic bee fly genus, which includes 11 species, including six species we describe as new here Sisyromyia albisquama sp. nov., Sisyromyia angustivitta sp. nov., Sisyromyia elongata sp. nov., Sisyromyia maculipennis sp. nov., Sisyromyia umbra sp. nov., Sisyromyia vittata sp. nov. The genus can be easily distinguished from other Australian genera in the subfamily by having a one-segmented antennal flagellum, subapex of flagellum with some long hairs; a pale median stripe present on the abdomen consisting of dense, decumbent short scales, cell r5 open; cell br nearly as long as cell bm, crossvein m-m located on base of cell dm; crossvein m-m long, nearly as long as crossvein r-m. We also recognized one new synonym, and propose a new combination for Sisyromyia binghi Evenhuis. A key to species of Sisyromyia is provided, and we extensively illustrate their internal and external morphology.The larva of Agriocnemis minima Selys, 1879 is described and illustrated for the first time, based on reared specimens collected from Thailand. Selected larvae of Agrioncnemis Selys, 1877 were matched with their adults by DNA barcoding. The mitochondrial COI gene (658 bp) of three species (A. minima, A. femina femina (Brauer, 1868), and A. pygmaea (Rambur, 1842)) occurring in Thailand was analysed to confirm the species identification and to determine the association between the larva and adult stages. The larva of A. minima can be distinguished from known species by the following combination of characteristics 1) long simple setae on the antennomeres I and II, 2) protrusion of the male cerci as long as 0.5× the S10, and 3) tufts of spiniform setae on the lateral occiput margin and on the ventral view of the compound eyes. Comparisons to known larvae of Agriocnemis and those of some other subfamily Agriocnemidinae members are also provided.Two new species in the genus Destinoides Cai He, D. hainanensis and D. rubeus spp. nov. from China are described and illustrated. A checklist and key to the known species of Destinoides are provided.Male adults of gnathiid isopods (Crustacea; Isopoda; Gnathiidae) have remarkably developed rectangular-shaped cephalosomes and mandibles in most species. Tenerognathia visus Tanaka, 2005 belongs to a monospecific genus having remarkable characters in male morphology; reduced mandibles and large eyes occupying the whole of an elliptical cephalosome. The original description of T. visus is based on male adult specimens from coral rubble. This study found adult males and their larvae of T. visus attracted by light. Furthermore, specimens of female adults were observed by laboratory rearing of praniza larvae. In this study, morphologies of larvae and female adults of T. visus are described and notes on mating behavior in a laboratory aquarium are provided.The rivorum species-group of the genus Leucania (Noctuidae Noctuinae Leucaniini) is circumscribed and taxonomically revised, with the inclusion of three species. New taxonomic hypotheses were achieved through the morphological analysis of about 250 specimens allied to the type material of L. rivorum Guenée, 1852; L. pampa Schaus, 1894, stat. rev.; and Neleucania multistria Köhler, 1947, stat. rev., the last two resurrected from synonymy with L. rivorum and Dargida lithophilus (Butler, 1882), respectively. Adult habitus and morphology of the genitalia support the transfer of Neleucania multistria to Leucania, comb. nov. Lectotypes for L. rivorum and L. pampa are designated to ensure nomenclatural stability and recognizability of these taxa. Additionally, the similar, rust-colored species Leucania chejela (Schaus, 1921) is compared with species of the rivorum species-group, and is recorded from South America for the first time. All species of the rivorum group are re-described, with high-resolution images of taxonomic characters of the adults (head, patagium, and male and female genitalia), and updated distributional maps presented.Selenomorphini is a small tribe previously comprising four genera and 21 species, with distribution in the New World and New Caledonia. Herein are described three new species of Pachyopsis Uhler from Brazil P. fasciatus sp. nov., P. nigrifacis sp. nov., and P. pallidus sp. nov. Two new Brazilian monotypic genera, Parapachyopsis gen. nov. and Uhleriana gen. nov. are proposed, based on P. tenebris sp. nov. and U. tornatucephala sp. nov., and an updated key to genera of Selenomorphini is provided. Pachyopsis and Scaroidana are reviewed and the detailed morphology is redescribed, including characters not previously observed and the first illustrations of the female genitalia. The type-species Scaroidana flavida Osborn is redescribed and a key to males of Pachyopsis is provided. Additionally new State records for Brazil are reported for Pachyopsis vicosensis Coelho, Scaroidana flulvula Osborn and Scaroidana flavida Osborn. Detailed comparative notes between the new genera, Pachyopsis and Scaroidana are given.A new species of the genus Barsine, viz. Barsine fangchenglaiae Huang, Volynkin, Černý Wang sp. nov. from SW China, N Thailand and N Vietnam is described. The following six taxa are confirmed as new records to China B. pretiosa Moore, 1879, B. defecta defecta Walker, 1854, B. gratissima (de Joannis, 1930), B. flammealis Moore, 1878, B. mactans Butler, 1877 and Barsine vinhphucensis Spitsyn et al., 2018. The new synonymy is established Barsine pretiosa Moore, 1879 = Barsine pseudomactans Volynkin Černý, 2016, syn. nov. Adults and genitalia of all species aforementioned are illustrated.
