A review of the Pseudachorutes fauna of the East Asia was performed, mainly based on fresh material from forest ecosystems of the Russian Far East and some adjoining regions. Six new species of the genus, namely P. aleksandrae sp. nov., P. armatus sp. nov., P. minimus sp. nov., P. variabilis sp. nov., P. concinnus sp. nov. and P. morulifer sp. nov., are described and extensive remarks on further six congeners, i.e. P. andrei Weiner Najt, P. hitakamiensis Tamura, P. isawaensis Tamura, P. kangchenjungae Yosii, P. longisetis Yosii and P. polychaetosus Gao Palacios-Vargas, previously known from the studied region, are given. Pseudachorutes conicus Lee Kim and P. sibiricus Rusek, are considered as probable junior synonyms of P. longisetis and P. andrei, respectively. Pseudachorutes boerneri Schӧtt is recorded for the first time in the eastern Palaearctic and redescribed based on materials from Yakutia, Khabarovsk Territory and Southern Primor'e. A regional key to the mentioned species and a summarizing table of diagnostic characters of all regional congeners are also provided.Cyana Walker, 1854 is one of the most species-rich Erebiidae genera within the tribe Lithosiini Billberg of the subfamily Arctiinae Leach. The genus is widespread from Sub-Saharan Africa and Madagascar through southern and eastern Asia to New Guinea and Australia with a diversity hot spot in South East Asia. A striking species with contrasting red and orange wing pattern, C. bellissima (Moore, 1878) was described from northern India and recorded from the Himalayas, China and Indochina (Fang 2000; Černý Pinratana 2009; Singh et al. 2020). Another closely related species, C. stresemanni (Rothschild, 1936) (= bellissima inouei Kishida, 1993) is distributed in the Peninsular Malaysia (Rothschild 1936; Kishida 1993; Bucsek 2012). During examination of extensive unsorted Lithosiini materials housed in the MWM/ZSM and the private collection of the senior author, a series of peculiar specimens from southern Vietnam provisionally identified as 'C. bellissima' was found. These specimens, however, display certain external differences from other populations of C. bellissima and C. stresemanni, suggesting the presence of a further taxon related to C. bellissima. The examination of the male and the female genitalia of the southern Vietnamese specimens has confirmed their specific distinctness and they are described in this paper as a new species.A new species of Dysdera Latreille, 1804 is described from the South-Western Kopet Dagh, Turkmenistan, on the basis of both sexes. The species is compared to its closest congener Dysdera kronebergi Dunin, 1992, and tentatively assigned to the D. asiatica species-group.Ten species of Cephennomicrus are currently known to occur in Japan, predominantly in the Ryūkyū Archipelago. These extremely small beetles (adults of Japanese species do not exceed 1.2 mm) are rarely collected, and their true diversity may be in fact much greater. Two more species are described in the present study C. aji sp. n. inhabiting Okinawa island, and C. ushimanus sp. n. found on Amami Ôshima island. Cephennomicrus aji has the smallest adults of all Japanese Scydmaeninae; the holotype male measures merely 0.66 mm of body length. The distribution of Japanese Cephennomicrus species is summarized, with the aedeagus of each species illustrated on the distribution map, to facilitate identifications and further study on this broadly distributed but poorly known cephenniine genus.Phonotimpus padillai sp. nov. is described on the basis of morphological characteristics of both sexes males are easily distinguished by the shape of the embolus and females by the shape of the copulatory openings. Additionally, Gosiphrurus schulzefenai Chamberlin Ivie, 1936 is transferred to the genus Phonotimpus Gertsch Davis, 1940, based on the redescription of the female and first description of the male, with an update of the diagnosis of this species.Oxynoemacheilus amanos, new species, is described from İncesu spring in the upper Hupnik drainage, a northern tributary of the lower Orontes in Turkey. It is distinguished from the other Oxynoemacheilus species in the Eastern Mediterranean Sea basin by possession of an incomplete lateral line with 23-45 pores, terminating between the vertical through the dorsal fin origin and the anus, 10-13 pores in the infraorbital canal, a deeply emarginate caudal fin, no suborbital groove in the male, and a series of irregularly shaped and set dark-brown bars on the flank, not connected to saddles on the back.Four species of Triplocania are described and illustrated (T. brancoi n. sp., T. ferratilis n. sp., T. pains n. sp., and T. zairae n. sp.), all based on male specimens collected in caves of the Brazilian state of Minas Gerais. An identification key is presented to the Brazilian species of Triplocania, based on males, together with information on both sexes and distributions.We describe two new species of Cypricercus, Cypricercus alfredo sp. nov. and Cypricercus tiao sp. nov., and briefly redescribe the female of Cypricercus centrurus (Klie, 1940) from Brazilian floodplains. Both new species have the elongated carapace which is characteristic of the genus. Cypricercus alfredo sp. nov. was found as both sexual and asexual populations and has a posterior spine on the right valve and differs from the Brazilian C. centrurus by the position and the size of spine and the size and shape of the carapace. Cypricercus tiao sp. nov. was found as one asexual population only and lacks a posterior spine on the right valve.  https://www.selleckchem.com/products/danirixin.html  Cypricercus populations in Brazil mostly consist exclusively of asexual females, but some sexual populations and populations with mixed reproduction can also be found. This genus occurs primarily in the Southern Hemisphere, but some species can also be found in the southern part of North America and in India. We also present a re-appraisal of all species presently allocated to the genus, primarily based on original descriptions.The genus Micaria Westring, 1851 (Araneae, Gnaphosidae) is a group of small (1.85-5 mm) ant-like spiders that can be distinguished from other gnaphosids by their piriform gland spigots that are similar in size to the major ampullate gland spigots. According to the World Spider Catalog, there are 105 species of Micaria in the world, of which only three species are known from the African part of the Afrotropical Region, namely M. chrysis (Simon, 1910), M. tersissima Simon, 1910 and M. beaufortia (Tucker, 1923). The objectives of this study were to revise Micaria in the Afrotropical Region, providing new and updated records for each of the species, evaluating the relationships between them using COI barcoding data, and providing information on their biology, mimetic relationships and feeding ecology. These objectives were met by collecting fresh material from the KwaZulu-Natal, Western Cape, Northern Cape and Free State provinces in South Africa. Fresh material of M. tersissima and M. chrysis were collected from their type localities, Komaggas and Port Nolloth (Northern Cape Province), respectively, for identification and DNA analyses.
