The present paper deals with two new species, Yaginumaella pulchella sp. nov. and Yaginumaella hubeiensis sp. nov. Distributional data, as well as illustrations of body and copulatory organs, are provided. Descriptions of their morphology are given. The differences between the new species and their related taxa are discussed.
Two new species of the genus Eponisiella Emeljanov, 1984 are described and illustrated from China (Guizhou and Shandong Provinces). These are E. dafangensis sp. nov. and E. shandongensis sp. nov., giving the genus eight species in total. A key to the species of Eponisiella is provided as well as a map of their geographic distribution, which is briefly discussed.
Three new species of the bamboo-feeding genus Bambusiphaga Huang & Ding, 1979, B. parvula sp. nov., B. angulosa sp. nov., and B. nigrigena sp. nov., are described and illustrated from China. A key to species of the genus is provided. Habitus photos for adults and illustrations of male genitalia are also given.
The first Oriental species of the genus Trichopsomyia Williston, 1888, Trichopsomyia pilosa sp. nov. (Java), has been discovered and is now described. This Oriental species of Trichopsomyia has several characters strongly differing from the other species within this genus. It is hypothesized that it forms a separate group within Trichopsomyia. One species, Trichopsomyia formiciphila Downes, Skevington & Thompson, 2017, from Australia, is similar to the Oriental species described here, and the group is named after this first described species, hence the formiciphila group. The characters for a future phylogenetic analysis are discussed. The character states of the pilosity of the katepisternum and the shape of the metasternum hitherto used in a phylogenetic analysis of Syrphidae Latreille, 1802 are discussed too.
Two subspecies of Cosmodela duponti (Dejean) (Coleoptera: Cicindelidae) are elevated to species rank: Cosmodela barmanica (Gestro) and C. indica (Fleutiaux). The lectotypes of all the above-mentioned species are designated as well. Short redescriptions of the three species are provided together with a key, and illustrations of their habitus.
The Oriental species of the genus Sphegina Meigen, 1822 are revised. The following 43 new species are described: Sphegina (Sphegina) abbreviata sp. nov. (Nepal), S. (S.) angustata sp. nov.

(A.) umbrosa sp. nov. (China), S. (A.) verrucosa sp. nov. (Vietnam) and S. (A.) vietnamensis sp. nov. (Vietnam). Sphegina. (A.) tenuis Brunetti, 1915 is not a synonym of S. (A.) javana de Meijere, 1914. The males of S. (A.) apicalis Shiraki, 1930, S. (A.) tricoloripes Brunetti, 1915 and S. (A.) varidissima Shiraki, 1930 and the females of S. (A.) achaeta Hippa, van Steenis & Mutin, 2015, S. (A.) index Hippa, van Steenis & Mutin, 2015, S. (A.) mirifica Hippa, van Steenis & Mutin, 2015 and S. (S.) quadriseta Huo & Ren, 2006 are described for the first time. Sphegina (S.) quadriseta is recorded for the first time in the Oriental region. A key to all the Oriental species of Sphegina is provided. The Oriental fauna of Sphegina now comprises 94 species.
Revision of the genus Sulciclivina Balkenohl, 2022 from Asia (Coleoptera, Carabidae, Clivinini)
(2023)
The Oriental genus Sulciclivina is revised based on 770 specimens. Sulciclivina attenuata attenuata (Herbst, 1806), S. bhamoensis (Bates, 1892), S. striata striata (Putzeys, 1846), S. sulcigera (Putzeys, 1866), and S. sagittaria sagittaria (Bates, 1892) are redescribed. In order to maintain stability of the nomenclature, lectotypes have been designated for S. attenuata attenuata, S. bhamoensis, S. striata striata, and S. sagittaria sagittaria. The following twelve new taxa are described: S. attenuata semireticulata subsp. nov., S. striata kottea subsp. nov., S. coxisetosa sp. nov., S. basiangusta sp. nov., S. splendida sp. nov., S. mikirensis sp. nov., S. karelkulti karelkulti sp. nov., S. karelkulti medanensis subsp. nov., S. curvata sp. nov., S. oculiangusta sp. nov., S. andrewesi sp. nov., and S. sagittaria singaporensis subsp. nov. An identification key to the species is provided which includes the characterization of the two new species groups attenuata and sagittaria. All taxa are figured including male and female genitalia, if available. The available faunistic information is provided, and distribution records are displayed on a map.
The planthopper genus Arcofaciella Fennah, 1956 (Hemiptera: Fulgoromorpha: Delphacidae) is reviewed. Four species are recognized, of which A. obflexa Guo & Liang, 2005 and A. verrucosa Fennah, 1956 are redescribed, and one new species, A. indiana sp. nov., is described. Habitus photos for adults and illustrations of male genitalia (excluding A. penangensis (Muir, 1919)) are given. A key for identifying the species of Arcofaciella is also provided.
The genus Paragymnopleurus Shipp, 1897 (Coleoptera: Scarabaeidae: Scarabaeinae: Gymnopleurini) is characterized and its constituent taxa are keyed and illustrated. Twelve species and five subspecies are deemed valid, and five species groups are recognized. Three new synonymies include: Paragymnopleurus stipes japonicus Balthasar is synonymized with P. ambiguus Janssens, and P. maurus malayanus Ochi and Kon and P. maurus pauliani Janssens are synonymized with the nominotypical subspecies. First country and provincial records are reported for P. brahminus (Waterhouse), P. maurus (Sharp) and P. sinuatus szechouanicus Balthasar. A lectotype is here designated for Gymnopleurus singularis Waterhouse, validating an unpublished designation. A checklist of valid species and synonyms is provided.
A taxonomic review was conducted of the type material of Quedius rove beetles (including Indoquedius, previously a subgenus) described by Otto Scheerpeltz from the 1934 Swedish expedition by René Malaise to Kambaiti, Myanmar. The specimens were mistakenly thought to be lost or compromised during the Second World War, and so the corresponding available names were not considered in the extensive taxonomic study of Quedius from the Himalayan Region and mainland China that has followed. This has resulted in the following synonyms: Indoquedius nonparallelus Zhao & Zhou, 2010 syn. nov. = I. malaisei (Scheerpeltz, 1965); I. baliyo Smetana, 1988 syn. nov. = I. micantiventris (Scheerpeltz, 1965); I. sanguinipennis (Scheerpeltz, 1965) syn. nov., I. bicoloris Smetana, 2014 syn. nov. = I. parallelicollis (Scheerpeltz, 1965); Quedius cornutus Cai et al., 2015 syn. nov. = Q. rutilipennis Scheerpeltz, 1965; Q. sundar Smetana, 1988 syn. nov., Q. hecato Smetana, 2012 syn. nov. = Q. semilaeviventris Scheerpeltz, 1965; Q. kambaitiensis Scheerpeltz, 1965 syn. nov. = Q. muscicola Cameron, 1932. The species collected by Malaise were treated within the most recent phylogenetic context, resulting in Malaisdius gen. nov., M. ruficeps (Scheerpeltz) comb. nov., and new or revised morphological concepts for the Apicicornis and Masasatoi species groups of Quedius (Microsaurus), and the Muscicola group of Quedius (Raphirus). Malaisdius smetanai gen. et sp. nov. is described from Nepal.
