On Some Weevil Taxa of the Subfamily Entiminae (Coleoptera, Curculionidae) Described by V. I. Motschulsky from Japan and New Data on the Morphology of the Tribes Cneorhinini and Tanymecini

Abstract: Lectotypes of Cneorhinus viridimetallicus Motschulsky, 1860, C. cuprescens Motschulsky, 1866, C. nodosus Motschulsky, 1860, and Dermatodes carinulatus Motschulsky, 1866 are designated. A new synonymy Catapionus viridimetallicus (Motschulsky, 1860) (= Cneorhinus cuprescens Motschulsky, 1866, syn. n.) and a new combination Scepticus carinulatus (Motschulsky, 1866), comb. n. are established. New data on the morphology of some genera of the tribes Cneorhinini and Tanymecini are presented. The record of Amystax fasciatus Roelofs, 1873 for Kunashir Island is shown to be based on misidentification of Scepticus carinulatus. © 2021, The Author(s).
