Bosporomias gen. n., a New Genus of the Weevil Subfamily Entiminae from Taman Peninsula (Coleoptera, Curculionidae)

摘要

The new genus Bosporomias gen. n. is erected for a single species, B. pruinosulus sp. n. from Taman Peninsula. The systematic position of the genus is unclear. The type species is similar to some representatives of the tribes Sciaphilini and Trachyphloeini, especially to those of the genus Brachysomus Schoenh., and bears some resemblance to species of Omias Germ, and Trachyphloeus Germ. B. pruinosulus sp. n. differs from all species of the genus Brachysomus Schoenh. in the structure of the head, antennae, tarsi, and in the characteristic pubescence. The new genus lacks all apomorphies of the tribe Trachyphloeini: the very dense cover consisting of three-dimensional multiradiate scales, glabrous hypertrophied epistome with sharply projecting anterior angles and sharp posterior keel, and specific structure of the apical fringe of spines on the tibiae.
