A Taxonomic Revision of the Genus <i>Cionus</i> (Coleoptera, Curculionidae) from the Oriental Region

Abstract

Oriental species of the genus Cionus are herein revised for the first time. Eight species are recognized as distinct based on morphological characters of adults. One species is described as new: C. ottomerkli sp. nov., from India, whereas the name vossi (nom. nov.) is proposed for Cionus flavoguttatus Voss, 1957 (not Stierlin, 1893). The following new synonymy is established: Cionus indicus Desbrochers des Loges, 1890 (=Cionus albosparsus Faust, 1898 syn. nov.). Lectotypes of Cionus albosparsus Faust, 1898; Cionus flavoguttatus Voss, 1957; Cionus indicus Desbrochers des Loges, 1890; Cionus obesus Pascoe, 1883; and Cionus tonkinensis Wingelmüller, 1915, are designated.
