Oiketicoidesgohadoensis Roh & Lee, sp. nov. is described as new to science. The morphology of male adult, including genitalia, is described, and DNA barcodes for precise identification of the species are provided. A parasitoid, Neophryxepsychidis Townsend, 1916 (Diptera, Tachinidae) of O.gohadoensis is also reported for the first time in Korea, together with its DNA barcode sequence.

Two new species of Diploexochus are described, Diploexochuscacique sp. nov. from Cerro Bañaderos in Hatonuevo, La Guajira, and Diploexochustroglobius sp. nov. from Roca Madre Cave, Toluviejo, Sucre, both from the Tropical Dry Forest (TDF) areas of the Colombian Caribbean. The latter represent the first troglobitic species of the genus. Moreover, based on specimens from Sierra Nevada de Santa Marta, Magdalena (type locality), Venezillobrevispinis is placed into Diploexochus and an identification key for all species of the genus is given. The present work describes the first troglobitic species of the genus, and expand the knowledge of its distribution in northern South America.

The genus Campylomyza Meigen, 1818, belongs to the subfamily Micromyinae (Diptera, Cecidomyiidae). The genus, comprising 40 species, is best known in the Palearctic Region. To date, four species are recorded in Korea: Campylomyzaappendiculata, C.flavipes, C.furva, and C.spinata. Based on our field investigations from 2017 to 2020, five species are newly recorded from Korea (C.abjecta, C.aborigena, C.cornuta, C.cavitata, and C.cingulata) and seven new species are described (C.ambulata sp. nov., C.angusta sp. nov., C.convexa sp. nov., C.cornigera sp. nov., C.hori sp. nov., C.odae sp. nov., and C.salicia sp. nov.), based on morphological identification and molecular analyses. Detailed morphological and molecular data, including mitochondrial COI sequences are provided, with species diagnosis, descriptions, and keys for identification of those species.

Two new species of the dragon millipede genus Hylomus Cook & Loomis, 1924 are described from mountainous areas in northern Vietnam, namely Hylomuspiccolo sp. nov. and Hylomusborealis sp. nov. The COI barcodes are provided for these species, and an identification key is presented to all Vietnamese Hylomus species.

The family Dalodesmidae Cook, 1896 in the fauna of Madagascar is reviewed and shown to presently encompass eight species in three genera: Dalodesmus Cook, 1896 (six species), Eutubercularium Brölemann, 1916 (one species), and Phymatodesmus de Saussure & Zehntner, 1897 (one species). These genera are diagnosed, and their respective species keyed, all being endemic to Madagascar proper and/or the immediately adjacent islets of Nosy Be and/or Nosy Sakatia. Dalodesmus currently contains six species, including two new, all supplied either with brief descriptive notes and available iconography or extensive descriptions and new illustrations, as follows: D.hamatus (Brandt, 1841), from an unspecified locality in Madagascar, now redescribed from a male specimen from Makira, northeastern Madagascar; D.odontopezus (Attems, 1898), from Nosy Be Isle; D.orator Hoffman, 1974, from Ambohimitombo, central Madagascar; D.tectus Cook, 1896 (= D.hova (de Saussure & Zehntner, 1897), syn. nov.), originally described from an unspecified locality in central Madagascar, with a male type and additional males identified as D.hova recorded from the Andasibe National Park (= Périnet) in east-central Madagascar. Additionally, two new species are described, D.speophilus sp. nov., from Grotte de Anjohibe, northwestern Madagascar, and D.kompantsevi sp. nov., from Montagne d'Ambre, northern Madagascar. Both the type species of Dalodesmus and its synonym Tubercularium Attems, 1898, D.tectus and D.odontopezus, respectively, are partly revised and illustrated based on holotypes, while D.hamatus is duly described and illustrated based on the first discovery of a male. Both Eutubercularium and Phymatodesmus are still monospecific, comprising only E.voeltzkowi (Mesibov, Wesener & Hollier, 2018), from Nosy Be Isle, and P.sakalava (de Saussure & Zehntner, 1901), from Andasibe, respectively. The latter species is fully redescribed and illustrated for the first time from male material.

The orb-weaver spider genus Yaginumia Archer, 1960 from China is revised, and three species, including two new species, are recognized: Y.medog Mi & Wang, sp. nov. (♂♀) from Xizang and Y.qiong Mi & Wang, sp. nov. (♂♀) from Hainan; the type species, Y.sia (Strand, 1906) (♂♀), is redescribed based on specimens from Guizhou and Hubei. A distributional map of the studied specimens is also provided.

This study describes a new species of Polyxenida from China, Lophoturussineprocessus sp. nov., along with a species newly recorded from China: Eudigraphisnigricans (Miyosi, 1947), and provides additional descriptions of Eudigraphissinensis Ishii & Liang, 1990 and Polyxenushangzhoensis Ishii & Liang, 1990. The study conducted mitochondrial cytochrome c oxidase subunit I (COI) sequencing for all four species and constructed a phylogenetic tree based on the molecular data. The comprehensive morphological descriptions and molecular analyses confirm the addition of one new species and one newly recorded species for the Polyxenida fauna of China, elevating the total number of known Polyxenida species in the country from 10 to 12. The study also includes an identification key for Polyxenida species in China.

A new forest-dwelling species of the Cyrtodactyluschauquangensis group is described from southwestern Yunnan Province, China. Phylogenetically, it was recovered as the sister species of C.zhenkangensis, with a genetic distance of 9.2% in the ND2 gene. Morphologically, the new species can be separated from C.zhenkangensis by the discontinuity of enlarged femoral scales and enlarged precloacal scales, the absence of femoral pores, and the difference in dorsal color pattern. In addition, although the new species and C.zhenkangensis are distributed relatively close, their habitats are clearly different. Cyrtodactyluszhenkangensis inhabits karst limestone, while the new species inhabits forest. The new species is the 29^th species of the C.chauquangensis group and the third forest-dwelling species of this group.

A comprehensive revision is presented of the Oriental and Australasian diving beetle genus Sandracottus Sharp, 1882 (Coleoptera: Dytiscidae: Dytiscinae: Aciliini) and seven junior subjective synonyms are proposed. Sandracottusguerini Balfour-Browne, 1939, syn. nov. is a junior subjective synonym of S.femoralis Heller, 1934; S.manipurensis Vazirani, 1969, syn. nov. of S.hunteri (Crotch, 1872); S.mixtus Blanchard, 1843, syn. nov. of S.chevrolati (Aubé, 1838); and S.angulifer Heller, 1934, syn. nov., S.nauticus Sharp, 1882, syn. nov., and S.palawanensis Satô, 1978, syn. nov. of S.maculatus (Wehncke, 1876). Finally, S.vijayakumari Anand et al., 2021, syn. nov. is a new synonym of S.dejeanii (Aubé, 1838). New status is assigned to S.bakewelliiguttatus (Sharp, 1882), stat. nov. as well as S.hunteri (Crotch, 1872), stat. rev. Lectotypes are designated for the following taxa: Dytiscusflavocinctus Guérin-Méneville, 1830, Hydaticuschevrolati Aubé, 1838, Hydaticusinsignis Wehncke, 1876, Sandracottusbaeri Régimbart, 1899, Sandracottusbizonatus Régimbart, 1899, and Sandracottusornatus Sharp, 1882. A neotype is designated for Hydaticusmaculatus Wehncke, 1876. In total, three Oriental species, two of which also occur in the East Palaearctic, six Southeast Asian species, one species from New Guinea and the Moluccas, and one from Australia with an endemic subspecies in Central Australia (S.bakewelliiguttatus) are recognised. Each taxon is presented with a diagnosis, habitat preferences, conservation assessments, distribution data, and a comprehensive bibliography. Important characters (habitus, dorsal colouration, median lobes and parameres) are illustrated. All currently valid taxa are redescribed. Sandracottusjaechi Wewalka & Vazirani, 1975 from Sri Lanka, S.bizonatus from Borneo, S.insignis from the Philippines and S.rotundus Sharp, 1882 from Sulawesi are recommended to be listed in the next IUCN red data book. A key to all species is provided.

The ant genus Zasphinctus are fascinating ants due to their distinctive morphology, ecology, and rarity. In this study, a comprehensive revision of Zasphinctus in the Afrotropical region is presented, through a combination of morphological examination under the light microscope and three-dimensional (3D) cyber-taxonomy based on microtomography (micro-CT). Micro-CT based 3D surface models of all species were used for virtual morphological visualisation and examination. The 3D models were virtually visualised, rotated, scaled, and dissected in order to obtain the best shape data for whole specimens or individual body parts. This approach offered a greatly improved character evaluation, allowing the development of an updated taxonomic species delimitation system for the genus. Our revision recognises eight worker-based species, of which three were previously known and five are newly described in this study. Furthermore, based on distinctive morphological differences, two species groups are also proposed. The Z.obamai group includes the species Z.obamai Hita Garcia, 2017 (Kenya), Z.lumumbai Hita Garcia & Gómez, sp. nov. (Democratic Republic of Congo), and Z.wilsoni Hita Garcia, 2017 (Mozambique) while the Z.sarowiwai group contains Z.aprilia Hita Garcia & Gómez, sp. nov. (Democratic Republic of Congo, Uganda), Z.kouakoui Hita Garcia & Gómez, sp. nov. (Ivory Coast), Z.lolae Hita Garcia & Gómez sp. nov. (Ghana), Z.ndouri Hita Garcia & Gómez, sp. nov. (Senegal), and Z.sarowiwai Hita Garcia, 2017 (Cameroon). All species are easily distinguishable through a comprehensive character matrix illustrated by numerous diagnostic illustrations, as well as a traditional dichotomous identification key.
