2025-08-12T11:35:34+12:00

An annotated catalogue is presented for six subfamilies of Elateridae from India: Hemiopinae, Hypnoidinae, Lissominae, Negastriinae, Tetralobinae, and Thylacosterninae. A total of 104 species, belonging to 19 genera, are recognised—of which 82 species were originally discovered and described from India, and 53 are considered endemic to India. Hemiopinae includes 10 spp. in two genera: Hemiops Laporte, 1838 (seven spp.) and Legna Walker, 1858 (three spp.). Hypnoidinae contains 20 spp. in two genera, both belonging to the same tribe, Hypnoidini: Hypnoidus Dillwyn, 1829 (19 spp.) and Ligmargus Stibick, 1976 (one sp.). Lissominae is represented by 12 spp. in two tribes: Lissomini and Protelaterini. Lissomini comprises three spp. in two genera: Drapetes Dejean, 1821 (s. str.; one sp.) and Lissomus Dalman, 1824 (two spp.). Protelaterini includes nine spp. in one genus, Senodonia Laporte, 1838. Negastriinae contains 59 spp. in two tribes: Negastriini and Quasimusini. Negastriini contains 32 spp. in five genera: Arhaphes Candèze, 1860 (six spp.), Cardiohypnus Fleutiaux, 1928 (six spp.), Hemirrhaphes Candèze, 1878 (one sp.), Tropihypnus Reitter, 1905 (five spp.), and Zorochros Thomson, 1859 (14 spp.; subgenus Zorochros 12 spp., subgenus Thurana Stibick, 1971 two spp.). Quasimusini includes 27 spp. in four genera: Miquasus Kishii, 1959 (six spp.), Quasimus Gozis, 1886 (17 spp.), Wittmeroquasimus Dolin, 1993 (three spp.), and Yukoana Kishii, 1959 (one sp.). Tetralobinae includes two species in the tribe Tetralobini, within two genera: Sinelater Laurent, 1967 (one sp.) and Tetralobus Lepeletier & Audinet-Serville, 1828 (s. str.; one sp.). Thylacosterninae is represented by a single species in the genus Cussolenis Fleutiaux, 1918. For each taxon, we provide the type locality, whereabouts of the type material, distribution in India, general distribution and literature relevant to the Indian records. Cussolenis wallacei Muona, 2020 is reported from India for the first time, thus confirming the presence of Thylacosterninae in the country. The following species are recorded from Indian states for the first time: Hypnoidus beckeri Stibick, 1980 from Himachal Pradesh; Miquasus improvisus (Dolin, 2001) from Karnataka; Zorochros mussardi Dolin & Cate, 1998 from Karnataka & Kerala; Arhaphes luteipes Candèze, 1897 from Kerala & Tamil Nadu; Lissomus mastrucatus Gerstaecker, 1860 from Kerala & Tamil Nadu. Hypnoidus quadrimaculatus Vats & Chauhan, 1991 and Horistonotus spatulatus Vats & Chauhan, 1993 are transferred to Zorochros and Cardiohypnus, respectively, as Z. quadrimaculatus (Vats & Chauhan, 1991) comb. nov. and C. spatulatus (Vats & Chauhan, 1993) comb. nov. Additionally, we provide habitus photographs of newly recorded species, a distributional analysis with maps, a list of species not considered to occur in India, and a note on dubious assignment.

**A new species and an additional record of the genus Dilobitarsus Latreille (Coleoptera, Elateridae, Agrypninae) from Borneo**

2025-08-12T11:36:27+12:00

Elaterid beetles of the genus Dilobitarsus Latreille, 1834 (tribe Agrypnini Candèze, 1857; subfamily Agrypninae Candèze, 1857) are predominantly found in the New World. However, one species, Dilobitarsus pendleburyi Fleutiaux, 1934, lives in Southeast Asia. Determining the systematic position and taxonomic relationships among congeners remains challenging due to their isolated distribution in Asia. This study examined new specimens from Borneo, including a newly discovered species, D. lambirensis sp. nov., and discusses the morphological features of Southeast Asian species. The two Asian species are considered the most similar within the genus by sharing specific features.

**Two new species of Clavellotis (Copepoda: Lernaeopodidae) with an approach to the phylogeny of the genus and its relationships inside the Clavella-Branch**

2025-08-12T11:37:28+12:00

The identity of Clavellotis specimens parasitizing Chilean fishes has been determined using integrative taxonomy. Clavellotis dubius sp. nov., parasitic on Chromis crusma, can be distinguished from other species in the genus by a combination of characters, particularly the projection at the base of the cephalothorax, which shows variation related to the original aliform projection in Clavellotis. Additionally, its trunk is more elongated compared to the suborbicular trunk typical of other species. The male morphology aligns with the typical characteristics of the genus. The COI mtDNA genetic divergence between C. dubius sp. nov. and other Clavellotis ranges from 11.54% to 14.57%. Clavellotis girellae sp. nov., parasitic on Girella laevifrons, is morphologically similar to Clavellotis dilatata. However, males exhibit a unique dorsal projection shared only with Clavellotis sebastidis. The COI mtDNA genetic divergence for C. girellae sp. nov. ranges from 5.29% (with C. dilatata) to 12.94% (with C. sebastidis). With the addition of C. dubius and C. girellae, the number of Clavellotis species reported from Chilean fauna in the South Pacific increases to three, and the total number of species in the genus raises to 13. A phylogenetic analysis of Clavellotis is presented, including species from the South Pacific (C. dilatata, C. dubius sp. nov. and C. girellae sp. nov.), from South Atlantic (C. sebastidis) and Turkish Sea (Clavellotis fallax, Clavellotis strumosa, Clavellotis pagri and Clavellotis sargi). The analysis confirms the monophyly of Clavellotis, with C. sargi appearing as the most basal of the species within the genus. Additionally, the relationships of Clavellotis with other genera in the Clavella branch Alella, Clavella, Clavellisa Maxiclavella and Praeclavella—are also discussed.

**Preliminary taxonomic review of the genus Coptotriche Walsingham, 1890 (Lepidoptera: Tischeriidae) in China, including descriptions of three new species**

2025-08-12T11:38:25+12:00

Eight species of the genus Coptotriche Walsingham, 1890 are reported from China. Three species are described as new: C. basilata sp. nov., C. basicurvata sp. nov. and C. brevissima sp. nov. One species, C. minuta Diškus & Stonis, 2014, is recorded for the first time in China. Images of adults and genitalia of the new and newly recorded species are given, along with a key to the eight Coptotriche species distributed China.

**Description of a new species and a new record of the genus Acantholeria (Diptera: Heleomyzidae) in China**

2025-08-12T11:39:14+12:00

The genus Acantholeria Garrett, 1921 is a small member of the subfamily Heleomyzinae. Previously, only one species of this genus had been recorded in China: A. czernyi Gorodkov, 1966. In this study, one new species and one new record of Acantholeria are described from China: Acantholeria gorodkovi sp. nov. and Acantholeria desertorum Czerny, 1932. A key to the Palaearctic species of Acantholeria is also presented, and photographs of the adult insect of Acantholeria czernyi Gorodkov, 1966 are also provided.

**Description of the pupae of Brachodes species (Lepidoptera, Cossoidea, Brachodidae) with emphasis on diagnostic generic characters**

2025-08-12T11:40:56+12:00

This work presents the first descriptions of the pupal morphology of three species of Palaearctic brachodid moths, Brachodes compar (Staudinger, 1879), Brachodes flavescens (Turati, 1919) and Brachodes cf. rasata (Staudinger, 1900), which represent three distinct species groups within the genus. The main morphological features are described and illustrated with photographs and line drawings. Diagnostic features and a key for the identification of pupae for the genus Brachodes on the basis of the studied species and the related species, Brachodes funebris (Feisthammel, 1883) and Brachodes gaditana (Rambur, 1866) are proposed and discussed.

**First record of the genus Nemeritis Holmgren (Ichneumonidae, Campopleginae) from China, with descriptions of two new species**

The genus Nemeritis Holmgren (Hymenoptera, Ichneumonidae, Campopleginae) is reported from China for the first time. Two new species Nemeritis kophosa sp. nov. from Anhui province and Nemeritis petila sp. nov. from Sichuan province, are described and illustrated. A key to Chinese species of this genus is provided.

**A new species of Stictobura Crotch (Coleoptera: Coccinellidae) from the Western Ghats, India**

2025-08-12T11:42:31+12:00

The genus Stictobura Crotch (Coccinellidae: Sticholotidini) comprises only three species and is endemic to the Western Ghats of India, one of the world’s eight ‘hottest hotspots’ of biological diversity and endemism. In this paper, a fourth species, Stictobura ponmudiensis sp. nov., from the Western Ghats (Kerala), is described and illustrated. The unusual female genitalia in three Stictobura species are illustrated and compared for the first time.
