Annotated catalogue of the click-beetle subfamilies Hemiopinae, Hypnoidinae, Lissominae, Negastriinae, Tetralobinae, and Thylacosterninae (Coleoptera: Elateridae) of India

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 recognisedof 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 Candze, 1860 (six spp.), Cardiohypnus Fleutiaux, 1928 (six spp.), Hemirrhaphes Candze, 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 Candze, 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.
