A new species of the costal genus Brachemys Abeille de Perrin, 1890 is described from Crete, B. minotaurus n.sp. (Coleoptera, Malachiidae). The species is included in the subgenus Atelestodes Abeille de Perrin, 1890 due to the lack of modified protarsi, although the subgeneric classification of Brachemys may need to be revised. Specimens of the new species were found running on bare rock in the supralittoral zone, bearing a striking resemblance to ants.Sarcoglanidinae and Glanapteryginae catfishes are among the most unusual elements of the Neotropical freshwater fish fauna. Microcambeva ribeirae, M. barbata and M. draco are miniaturized Sarcoglanidinae known to occur in sandy microhabitats in drainages of the Brazilian Atlantic Forest. Due to their specific habitats, specimens of Microcambeva are rare in fish collections, and new records are considered noteworthy to warrant report. Recently, specimens of this genus were newly found in the Rio Doce basin in Minas Gerais and Espírito Santo States. Such new records expand the known geographic distribution of Microcambeva. Further records of Microcambeva for Rio Peruípe in south Bahia State are also reported. Comments on the distribution of Microcambeva species along the Atlantic Forest coastal basins and suggestions on its conservation status are also offered.A new species from rapids of Rio Aripuanã, Rio Madeira basin, in Brazil, and from the same type of habitat in the upper Rio Negro and upper Rio Orinoco basins in Brazil, Colombia, and Venezuela is described and assigned to the genus Hyphessobrycon. The new species presents an interrupted lateral line plus a single perforated scale on caudal peduncle and a small dark blotch on dorsal procurrent caudal-fin rays, features not found in the other species of Hyphessobrycon. Comments on the phylogenetic position of the new species, its rheophilic habits, and the biogeographic implications of its distribution are presented.Alpheus leptochiroides De Man, 1909, a poorly-known species originally described from the Kai Islands in eastern Indonesia, is reported from Kavieng, eastern Papua New Guinea, representing only the second record of this snapping shrimp and slightly extending its distribution range into the tropical western Pacific. The original description was based on a relatively young specimen, whereas the Kavieng specimen is clearly an adult male. Most importantly, several rather important characters of the species were omitted and/or not illustrated by De Man, including the unique and diagnostic rounded cuticular expansions on several areas of the third maxilliped, not present in any other alpheid shrimp. Therefore, a full redescription of the species is provided, with new detailed illustrations.Two new species of the genus Cephalophoxoides Gurjanova, 1977 are described. The material examined was collected during the Mini Biological Trawl (MBT) project, off Brazil's southeastern coast on the states of Rio de Janeiro and São Paulo, at depths ranging from 34 to 75 meters. Cephalophoxoides fortisetus sp. nov. resembles C. homilis (Barnard, 1960) in some general aspects of mandible, propodus of gnathopods 1-2, basis of pereopod 5 and rami of uropod 1. However, it can be distinguished by the latter species mainly by distinct characters on the maxilliped, gnathopod 1, uropod 2 and uropod 3. Also, the new species presents 1 short and 2 long stout setae on the lobes of telson as a notable character. Cephalophoxoides obtusimanus sp. nov. can be distinguished from its congeners by presenting gnathopod 1 with an obtuse and weakly chelate palm as an exclusive character of the genus. An identification key for all species of Cephalophoxoides of the world is provided.An annotated distributional checklist of the Coccinellidae of Bhutan is presented, enumerating 91 species, 17 of which are here recorded for the first time Shirozuella tibetina Wang, Ge Ren, 2012, Jauravia limbata (Motschulsky, 1858), Scymnus bourdilloni (Kapur, 1958), Illeis confusa Timberlake, 1943, Calvia albida Bielawski, 1972, Harmonia expalliata Sicard, 1913, H. octomaculata (Fabricius, 1781), H. sedecimnotata (Fabricius, 1801), Micraspis allardi (Mulsant, 1866), M. discolor (Fabricius, 1798), M. univittata (Hope, 1831), Oenopia adelgivora Poorani, 2002, O. billieti (Mulsant, 1853), O. smetanai Canepari, 1997, Afissula mysticoides (Sicard, 1913), Henosepilachna processa Li Cook, 1961 and H. septima (Dieke, 1947). One species, Propylea japonica (Thunberg, 1781), has to be removed from the list.                Nine species and two subspecies are hitherto only reported from the territory of Bhutan. The Bhutanese coccinellid fauna is still insufficiently known.Scaura Schwarz is a small, widely distributed Neotropical genus of stingless bees whose workers and males have the metabasitarsus as broad as or wider than the metatibia. The genus currently includes four valid species. A species complex composed of three additional species are described here as new (S. amazonica sp. n., S. aspera sp. n. and S. cearensis sp. n.). In addition to the descriptions and redescriptions of the species of Scaura, an illustrated identification key is presented, as well as updated geographical records.The genera Deltaspis Audinet-Serville, 1834 and Muscidora, Thomson, 1864 (Coleoptera Cerambycidae Cerambycinae Trachyderini) are revised. Two new genera Neoxoplus gen. nov. and Deltaspiopsis gen. nov., are described. Two species previously included in Deltaspis [D. cruentus, (LeConte, 1862), and D. ivae Beierl Barchet-Beierl, 1999] are transferred to the new genus Neoxoplus with N. cruentus designated as the type species. Four other Deltaspis species [D. alutacea Bates, 1885, D. marginella Bates, 1891, D. nigripennis Bates, 1880, and D. tumacacorii (Knull, 1944)] are transferred to Muscidora Thomson, 1864. Two species [D. disparilis Bates, 1891, and D. variabilis Bates, 1891] are transferred to the new genus Deltaspiopsis with D. disparilis designated as type species, and the remaining species [D. moesta Bates, 1885, D. rubens Bates, 1885, and D. subopaca Chemsak Linsley, 1982] are transferred to Crossidius LeConte, 1851. Keys to closely related genera, above mentioned genera and species along with illustrations of the available species in color are included. New species described include Muscidora bezarki sp. nov. from south-central Mexico (Puebla, Oaxaca); Muscidora coriacea sp. nov. from southeastern Mexico (Oaxaca and Chiapas); Muscidora nigrescens clinei subsp. nov. (Jalisco); and Muscidora similis sp. nov. from western Mexico (Sinaloa and Sonora).Twelve species from the Bay of Bengal, the Red Sea, the western Indian Ocean, and southwestern Australia are reclassified in Marmorofusus. These include Murex undulatus Gmelin, 1791, a senior synonym of Murex variegatus Perry, 1811 and Fusus laticostatus Deshayes, 1831, formerly regarded as a junior synonym of Marmorofusus nicobaricus (Röding, 1798); Murex verrucosus Gmelin, 1791 (synonyms Fusus tuberculatus Anton, 1839 non Lamarck, 1822, F. marmoratus Philippi, 1846 and F. rudicostatus G.B. Sowerby II, 1880); F. polygonoides Lamarck, 1822 (synonym F. biangulatus Deshayes, 1833); F. tuberculatus (Lamarck, 1822) (synonyms Fusus indicus Anton, 1839, F. maculiferus Tapparone Canefri, 1875, Fusinus t. priscai Bozzetti, 2013 and F. t. fuscobandatus Bozzetti, 2017); Fusus philippii Jonas in Philippi, 1846, an earlier name for Fusus tessellatus G.B. Sowerby II, 1880 (other probable synonyms Fusus exilis Menke, 1843, non Conrad, 1832 and Fusinus dampieri Finlay, 1930, replacement name for F. exilis Menke); Fusus oblitus (Reeve, 1847) (synonym Fusus turrispictus Hedley, 1918); F. leptorhynchus Tapparone Canefri, 1875 (synonym F. subquadratus G.B. Sowerby II, 1880), Fusinus vercoi Snyder, 2004; F. wellsi Snyder, 2004; F. brianoi Bozzetti, 2006; F. verbinneni Snyder, 2006; and F. https://www.selleckchem.com/products/bms-986158.html bishopi Petuch Berschauer, 2017. Fusus toreuma Deshayes, 1843, sometimes misidentified as M. tuberculatus, is a member of the Fusinus colus (Linnaeus, 1758) species group.Beetles of the Socotra Archipelago, Yemen, were catalogued. Altogether, 645 morphospecies from 56 families have been recognised from the Archipelago, of which 516 species (one with an additional two subspecies) were identified to the species level. Twenty-four, mostly widely distributed, species are recorded from the Socotra Archipelago for the first time, and three species are newly recorded for the islands Abd el Kuri (1) and Samha (2). Lithocharis socotrana Assing, 2015 (Staphylinidae), described from Socotra, is recorded from continental Yemen for the first time. Five incomplete or incorrect previous records are corrected. A total of 305 (47%) of all recorded species are considered to be endemic to the Socotra Archipelago. A total of 62 (10%) species are widely distributed Afrotropical species, and 35 (5.5%) East African species, often reaching also the Arabian Peninsula; 16 (2.5%) species occur in the eremial zone of Saharo-Arabian (or Saharo-Sindian) region. Only 14 (2%) species were previously known solely from the Arabian Peninsula; 30 (4.5%) species have cosmopolitan (and often anthropogenic) distributions; 28 (4.5%) species are widely distributed in (sub)tropical areas of the Old World; and 26 (4%) species have a predominantly western Palaearctic distribution. At present, 129 (20%) morphospecies remain unidentified; however, we expect that many of them represent as yet undescribed taxa endemic to the Archipelago.This paper presents a Catalogue of oribatid mites (Acari, Oribatida) recorded from the Malay Archipelago covering 113 years from 1905 to the end of 2018. The Malay Archipelago comprises countries located in the maritime area of Southeast Asia between the Indian and Pacific Oceans, viz., Malaysia, Singapore, Brunei, Indonesia, East Timor and the Philippines. Information compiled for each species includes references to the original description, subsequent re-combinations of specific name with other genera, and junior synonyms, if any, as well as the type locality, type habitat, later recorded habitats, and geographic distribution within and outside the Malay Archipelago. A historical review of explorations and taxonomic studies on oribatids in the various countries is also provided.                A total of 1,030 valid species including subspecies and 6 doubtful species have been recorded from the Malay Archipelago from 1905 to 2018. The valid species belong to 323 genera, 98 families and 34 superfamilies in a large island of Sulawesi has only 13 species records.                Endemism to the individual countries ranges from 36.1-60.7%, the highest of which are Singapore (60.7%) and Brunei (57.8%). The relatively better known and bigger countries have lower rates of endemism-47.4% for the Philippines, 46.8% for Malaysia, whereas Indonesia, with the largest land area and earliest records, has the lowest rate of 36.1%. Overall, 608 species or 59.0% of the total fauna of the Malay Archipelago are known so far only from this region.Three new species of Eutarsopolipus Berlese are described from the flightless pterostichine carabid genera Castelnaudia Tschitscherine and Trichosternus Chaudoir found in rainforests in eastern Queensland Eutarsopolipus piraticus sp. nov. from Trichosternus frater Darlington and T. mutatus Darlington in north-east Queensland; E. uncatus sp. nov. from C. obscuripennis (Macleay) in north-east Queensland; and E. verberatus sp. nov. from Castelnaudia eungella (Darlington) in middle-eastern Queensland and C. wilsoni (Castelnau) in south-east Queensland. These species are unique in Eutarsopolipus by having large hook-like unguinal setae on tarsi II-III. All species differ by only a few minor features, and the geographically isolated populations of E. verberatus could not be distinguished reliably. Surprisingly, the presence/absence of leg I claws and seta v″ on femur I, which have been used to create species groups, is intraspecifically variable. Species delimitation and the tarsal setation of Podapolipidae, particularly Eutarsopolipus, are also discussed.
