Abstract

For the first time an image key is presented for 31 species and subspecies of the Corimaliini (Curculionoidea: Nanophyinae) from the Western Palaearctic as well as 10 additional species for a large part of the Central Asia and South Africa. Habitus of males and females as well as the aedeagus are illustrated (focus stacking), and information on distribution is provided. Lectotype designations are presented for Corimalia aliena (Faust, 1890), orig. Nanophyes; Corimalia chinensis (Faust, 1890), orig. Nanophyes; Corimalia fausti (Reitter, 1890), orig. Nanophyes; Corimalia mongolica (Faust, 1890) orig. Nanophyes; Corimalia exsanguis Voss, 1960; Allomalia gemmaria (Faust, 1887), orig. Nanophyes; Hypophyes exiguus Faust, 1890, orig. Nanophyes. Corimalia multilineata (Peyerimhoff, 1930) is downgraded to a subspecies of Corimalia bilineata (Tournier, 1868). This work is primarily intended to pave the way for future AI-supported image recognition methods. For this purpose, the Curculio Institute (www.curci.de) is simultaneously providing high-resolution images with many detailed illustrations of all the species mentioned here in its catalogues of “Le Charançon”, most of which have not yet been seen in the print media or on the Internet (http://www.nanophyinae.curci.de).
