Review of the genus Chrysolina Motschulsky, 1860 (Coleoptera: Chrysomelidae) from Nepal Himalaya with description of a new species

Abstract

11 species and subspecies of Chrysolina hitherto known from Nepal are reviewed. From them only 4 species and 1 subspecies not attributed to exact subgenus can be treated as Himalayan typical alpine species. One more new species Chrysolina romandudkoi Mikhailov sp.n. is described from alpine zone of Eastern Nepal. Short aedeagus with broad anchor- shaped apex distinguishes it from all known Nepalese Chrysolina. Elytra with regular rows of punctures place the new species closer to Ch. dhaulagirica and Ch. hartmanni, but from both species having margins of elytra red fulvous it differs in uniformly dark bronze colour and lateral callus of pronotum not separated from disc. From Ch. nagaja and Ch. daccordii having uniformly bronze body and similar habitus it differs by regular punctures on elytra. The key to high mountain Chrysolina from Nepal Himalaya is provided. © RUSSIAN ENTOMOLOGICAL JOURNAL, 2019.
