We describe a new species of horse fly, Esenbeckia (Esenbeckia) auribrunnea n. sp. from Rondônia (Brazil) and Vaupés (Colombia), including diagnoses, distributional records, measurements of body and head, photographs in dorsal, lateral and ventral views, and illustrations of genitalia of a female paratype. In addition, we presented an updated and modified key to species in the subgenus described in the last 23 years based on Wilkerson Fairchild's (1983) key E. hirsutipalpus Wilkerson Fairchild, from Mexico, and E. gracilipalpis Chaney Hall, from Bolivia; E. griseipleura Chainey Hall, from Bolivia; E. peruviana Burger, from Peru; and E. rafaeli Limeira-de-Oliveira, from Maranhão state, Brazil. The species E. diaphana (Schiner) from Colombia, and E. distinguenda Lutz Castro from Rio de Janeiro, Brazil, are not included with justifications.A new species of the genus Protonemura Kempny, 1898 (Plecoptera Nemouridae Amphinemurinae) is described from the Ishizuchi Range of Shikoku Island, Japan, based on the male, female and Co1 sequences. Protonemura shimizui Murányi Gamboa sp. n. belongs to the P. orbiculata species group sensu Shimizu, 1998. The new species appears to be limited to the higher elevations of the Ishizuchi Range. Faunistic survey of the high elevation rheocrenes of the Ishizuchi Range is also presented.A new species, Amaurobius caucasicus sp. n., is described based on the holotype male and two male paratypes from Eastern Georgia. A similar species, A. hercegovinensis Kulczyński, 1915, known only from the original description is redescribed. The taxonomic status of Amaurobius species considered as nomina dubia and species described outside the Holarctic are also assessed. Amaurobius koponeni Marusik, Ballarin Omelko, 2012, syn. n. described from northern India is a junior synonym of A. jugorum L. Koch, 1868 and Amaurobius yanoianus Nakatsudi, 1943, syn. n. described from Micronesia is synonymised with the titanoecid species Pandava laminata (Thorell, 1878) a species known from Eastern Africa to Polynesia. Considerable size variation in A. antipovae Marusik et Kovblyuk, 2004 is briefly discussed.The primary types of longhorned beetles of Southwest University (SWU) are catalogued and figured. The original combination, current name, type locality, date and collector of type specimen are verified and presented. There are 69 holotypes and 86 paratypes in SWU. These 155 type specimens belong to three families, 51 genera, 71 species, of which 8 are in Disteniidae, 3 in Vesperidae, 3 in Prioninae, 12 in Lepturinae, 15 in Cerambycinae, and 30 in Lamiinae. A new synonym is proposed Paraleprodera insidiosa (Gahan, 1888) = Paraleprodera bimaculata Wang Chiang, 2000 syn. nov.Five species of the tribe Anerastiini from Ukraine are reviewed. Coenochroa ablutella (Zeller, 1839) is reported from Ukraine for the first time. Hypsotropa limbella Zeller, 1848 is removed from the list of Pyralidae of Ukraine as it was based on a misidentification. Five new synonyms are established Hafisia Amsel, 1950 syn. nov. of Zophodiodes Ragonot, 1887; Hafisia lundbladi Amsel, 1950 syn. nov. of Zophodiodes leucocostella Ragonot, 1887; Anerastia korbi Caradja, 1910 syn. nov. of Coenochroa ablutella (Zeller, 1839), Anerastia dubia Gerasimov, 1928 syn. nov. of Anerastia lotella (Hübner, [1813]), Peoria palaearctella (Turati, 1917) syn. nov. of Peoria incarnata (Staudinger, 1879) comb. nov. The females of C. ablutella and Z. leucocostella are described for the first time. Adults and genitalia are re-described and illustrated for all species.The Nearctic genus Philetus Melander, 1928 is a rarely collected group of empidid flies that contains two western species, namely P. memorandus Melander and P. schizophorus Melander. The genus was fully diagnosed by Cumming et al. (2016) with both known species redescribed and their distributions mapped. Here we describe a third species of Philetus from a single male collected recently in the Richardson Mountains of the Yukon Territory in Canada and provide a key to species based on male morphology. Terms used for adult structures follow those of Cumming Wood (2017) and methods follow those outlined in Cumming et al. (2016).The second and third larval instars of the Australian endemic dytiscid Chostonectes nebulosus (Macleay, 1871) are described and illustrated for the first time including a detailed chaetotaxic analysis of head capsule and appendages, legs, last abdominal segment and urogomphi. Collected larvae were successfully associated with adults using rearing and a molecular approach. The identification key and COI barcodes for C. nebulosus, C. gigas (Boheman, 1858) and C. johnsonii (Clark, 1862) are provided.Two new genera are proposed, Foveomicrus gen. n. (type species Foveomicrus indicus sp. n.) and Indomicrus gen. n. (type species Indomicrus chera sp. n.), for south Indian species of Cephenniini. The new taxa are classified as members of the 'Cephennomicrus group' of genera, characterized, among others, by a short and broad, button-like maxillary palpomere IV. Relationships of Foveomicrus and Indomicrus are discussed, and an updated identification key to world genera of Cephenniini is presented.New specimens and a re-examination of their holotypes have clarified the status of six nominal species of the extinct membracoid family Archijassidae from the Late Triassic (Norian) fossil insect localities at Mount Crosby, Denmark Hill and Dinmore in south-eastern Queensland. The 57 available tegmina ostensibly attributable to one or other of the six species are remarkably similar in venation and only vary in size and to a lesser extent in shape. The latter character varies subtlety across a continuum and is of no use in species definition. The tegmina, however, fall into two distinct size groups, and in the absence of any other discernible or consistent diagnostic characters, these groups are adopted as separate species, acknowledging, of course, the artificial nature of fossil insect species based on the size only of isolated wings. The following taxonomic changes result Mesojassus Tillyard, 1916 (= Triassojassus Tillyard, 1919, syn. https://www.selleckchem.com/products/gne-7883.html nov., = Triassocotis Evans, 1956, syn. nov., = Hylicellites Becker-Migdisova, 1962, syn.
