Leptoplectus kijimunaa Jałoszyński Nomura, sp. n. is described, based on a series of specimens collected on Okinawa Island, Japan. Morphological structures of the new species are illustrated in detail and compared to known characters of all remaining 14 congeners. As the diagnosis of Leptoplectus remains unclear, character variability within known species is discussed. It is concluded that within Palaearctic region, the bilobed labrum is a reliable character to distinguish this genus from other Euplectini. The placement of Labroplectus Kurbatov, treated as incertae sedis within the tribe Trichonychini in the latest edition of the Catalogue of Palaearctic Coleoptera, is verified and it is concluded that it should be maintained in Euplectini. An identification key to genera of northeastern Asian Euplectini is given. We also comment on outdated and inaccurate morphological nomenclature still broadly used in descriptions of new Pselaphinae taxa.The following two new species of biting midges of Culicoides Latreille are described and photographed Culicoides carbonelli Spinelli Martínez from Uruguay, and C. dellapei Spinelli, Ronderos Díaz from Argentina. Culicoides crucifer Clastrier, 1968 and C. hoffmani Fox, 1946 are diagnosed and newly recorded from Argentina, and the studied specimens are photographed.We describe a new species of the New Zealand diplodactylid gecko genus Naultinus. Molecular phylogenetics and distinctive morphological features support taxonomic separation of the populations on the northern half of Aupori Peninsula in the far north of the North Island as a new species, Naultinus flavirictus sp. nov. The specific epithet refers to the diagnostic yellow colour at the corners of the mouth. We discuss the conservation status of and threats to this novel taxon and to Te Paki, Northland-the unique area of New Zealand where it is found. We further discuss the distribution and possible function of bright mouth colour within Naultinus.Two new mayfly species of Clypeocaenis (Ephemeroptera Caenidae) are described based on nymphal and adult characters from Kaveri River, Kodagu, Karnataka, Southern India. The main characteristics that distinguish Clypeocaenis kaveri sp. nov. from other Oriental species are (i) fore femur with 4 long spines at middle of inner margin, a row of bifid spines at outer margin and row of bifid spines at subapical surface; (ii) dorsal surface of femora with complete transverse row of bifid setae located 3/4 distance from the base; (iii) forceps smaller than penis lobe. The main characteristics that distinguish Clypeocaenis napoklu sp. nov. from other Oriental species are (i) fore femur with 2 long spines at middle of inner margin and row of thin setae on outer margin; segment 2 with bifid spine at apex.(ii) dorsal surface of femora with incomplete transverse row of bifid setae located 2/3 distance from the base; (iii) forceps little longer than penis lobe. A key for the nymphs of described species has been provided.Two new species of genus Hydromanicus Brauer 1865 are described and illustrated Hydromanicus religiosus sp. nov. and Hydromanicus sikkimensis sp. nov. (both from Sikkim). Potamyia phaidra Malicky Chantaramongkol 1997 (from Meghalaya) and Cheumatopsyche chrysothemis Malicky Chantaramongkol 1997 and Hydromanicus inferior Chantaramongkol Malicky 1995 (both from West Bengal) are also reported for the first time from India. Further, the species Potamyia trenhona Oláh Barnard 2006 (in Oláh et al. 2006) is considered a synonym of P. phaidra based on the similarity in wing venation, male genitalic appendages, and phallic structure.A new species of Myxia Bahder Bartlett (Cixiidae Cixiinae Oecleini) is established as Myxia baynardi sp. n. collected from native palms in cloud forest habitat in Costa Rica. Placement in the genus Myxia is supported by molecular analysis of the cytochrome c oxidase subunit I (COI) and 18S loci as well as morphological characters. Haplaxius delta (Kramer) was collected along the Caribbean coast as a new country record for Costa Rica. Based on morphological characters observed and molecular analysis of COI and 18S, H. delta is herein moved to the genus Myxia.Final instar larvae of six species of the genus Hydroptila Dalman (Trichoptera, Hydroptilidae) belonging to three species groups are described based on Japanese specimens. These are H. phenianica Botosaneanu 1970, H. dampfi Ulmer 1929 and H. oguranis Kobayashi 1974 of the H. pulchricornis Species Group, H. kakidaensis Nozaki Tanida 2007 and H. botosaneanui Kumanski 1990 of the H. tineoides Species Group, and H. nanseiensis Ito 2011 (in Ito et al. 2011), which is unplaced to species group. They can be distinguished from each other by the color patterns of the head and thoracic nota, relative lengths of the longest head setae to the width of the head, and number of setae on the thorax. For discrimination of species groups, the arrangement of chloride epithelia of abdominal segments is likely to be useful, since it differs in the three species groups studied here.Historically, the taxonomic identification of the two snook species, Centropomus viridis and C. nigrescens, has been challenging due to their morphological similarity and the inconsistency of the characters used for diagnosis. Therefore, this study aimed to evaluate the usefulness of the morphologic, meristic, and morphometric characters currently being used to identify C. viridis and C. nigrescens, based on molecular data. The results showed that the gas-bladder shape (i.e., C. viridis with diverticula and C. nigrescens without diverticula) was the only morphological character univocally related to genetic identification. Likewise, geometric morphometrics separated two groups; each corresponds to only one of two genetically (and gas bladder shape) identified species. Of all the meristic characters examined, only the second dorsal fin ray count (nine for C. viridis and ten for C. nigrescens) was related to the gas bladder shape and genetic identity; therefore, it is the only external character with a diagnostic utility to separate each species.Based on two male and two female individuals, we describe a new genus and species of mud snake, Myanophis thanlyinensis gen. nov., sp. nov., from the vicinity of the campus of East Yangon University, Yangon, Thanlyin, Myanmar. This species differs from every other homalopsid species by the following combination of characters (1) dorsal scales smooth, row formula 21-21-19 or 21-21-17; (2) tail short, ratio tail length/SVL 0.185-0.204 in males, 0.160-0.167 in females; (3) nasal scales separated; (4) 125-126 ventral scales in males, 120-122 in females; (5) 38-39 subcaudal scales in males, 32-34 in females; and (6) hemipenis bilobed. Its matrilineal genealogy (based on analyses of 16S and cytochrome b sequences), associates Myanophis thanlyinensis gen. nov., sp. nov. Nafamostat cell line most closely with species of the genera Myrrophis and Gyiophis. The new taxon differs from the species of Myrrophis and Gyiophis by having a bilobed hemipenis (vs. unilobed). Myanophis thanlyinensis gen. nov., sp. nov. differs further from the species of Myrrophis by having 125-126 ventral scales in males and 120-122 in females (vs. 137-162 and 137-164, respectively), and 38-39 subcaudal scales in males and 32-34 in females (vs. 39-55 and 37-52, respectively). Myanophis thanlyinensis gen. nov., sp. nov. differs further from the species of Gyiophis by lacking dark blotches along flank (vs. present), and by having 21 dorsal scales rows at midbody (vs. 25). We provide an identification key to the homalopsid species known to occur in Myanmar. As a novelty to the classic holotype description and characterization, the individual has been genome sequenced by Illumina short-read technology and its genome has been assembled into a draft nuclear genome and a complete, annotated mitochondrial genome. This innovative approach comprehensively and permanently characterizes the genomic variation of the holotype.A new species of the genus Zodarion Walckenaer, 1826 is described based on material collected in different regions in Algeria. Morphological, diagnostic characters and illustrations of the genitalia of both sexes are presented. The samples reveal different phenological activities for males and females, and that the species occurs in agro-ecosystem habitats.A new whitefly species, Dialeurodes (Gigaleurodes) parakmeriae Wang sp. nov., collected on Parakmeria sp. (Magnoliales Magnoliaceae) in Shuangxikou (Zhejiang, China) is described using morphology, line illustrations, photographs and scanning electron microscope (SEM) images. In addition, Dialeurodes (Gigaleurodes) maxima Quaintance Baker, is reported as new to the fauna of China. An identification key to Chinese Dialeurodes (Gigaleurodes) species is provided. The holotype is deposited in the Insect Collection of Zhejiang Agriculture Forestry University (ZAFU).The stenopodidean shrimp Odontozona spongicola (Alcock Anderson, 1899) collected by the South Java Deep-Sea Biodiversity Expedition 2018 (SJADES 2018) is a new record from Indonesia. The specimen of O. spongicola recently listed from the South China Sea is also formally reported here in. The characteristcs and coloration of this rare species are described and illustrated.The genus Agrisius Walker (1855) is reported for the first time in Cambodia, for the new species Agrisius nigripunctata sp. n. Additionally, Agrisius fuliginosus is reported for the first time in Laos, Myanmar, China, Thailand and Vietnam. Illustrations of the adult and genitalia of Agrisius nigripunctata sp. n. and A. fuliginosus Moore are presented.Capezoum Adlbauer, 2003 is known only from male specimens. Herein, we describe two new species Capezoum richardi sp. nov. and C. brunneopunctatus sp. nov., from the Northern Cape region in South-Africa. The discovery of these new species, one of them represented by both sexes, allowed us to describe the hitherto unknown female. Moreover, the genus is transferred to the tribe Xystrocerini and a key to the species of the genus is provided. Lastly, the position of Mythozoum Thomson, 1878 in Cerambycidae is discussed.Kearfottia japonica Saigusa Sugimoto, sp. nov. (Lepidoptera, Psychidae) is described from Japan. This species is the second species of the genus Kearfottia hitherto known only from one Nearctic species, K. albifasciella Fernald, 1904. Bionomics of the Japanese species, systematic position and zoogeography of the genus are discussed.The new genus Cabardites gen. n. is erected for the Adites maculata (Poujade, 1886) species-group with Asura limbata Wileman, 1911 as the type species. Four new species are described Cabardites phifa Volynkin Černý, sp. n. (North Thailand), C. auco Volynkin Černý, sp. n. (North Vietnam), C. guanyin Volynkin Černý, sp. n. (East China), C. tiendung Volynkin Černý, sp. n. (North Vietnam) and C. varanagara Volynkin Černý, sp. n. (North Thailand). Cabardites pica (Wileman, 1911), stat. comb. n. is excluded from the synonymy with C. limbata stat. rev. comb. n. and raised to the species level. Parasiccia fuscipennis Hampson, 1914 is synonymized with C. pica. Parasiccia karenkonis Matsumura, 1930 is excluded from the synonymy with C. maculata (Poujade, 1886), comb. n. and its belonging to the genus Metaemene Hampson (Erebidae, Boletobiinae) proposed by Poole (1989) is confirmed Metaemene karenkonis (Matsumura, 1930), comb. rev. A new combination is established Cabardites maculata (Poujade, 1886), comb. n. The lectotypes are designated for Parasiccia maculata var.
