A New Genus and New Species of the Weevils (Coleoptera, Curculionidae: Entiminae) from the Sino-Tibetan Mountains with a Key to Asian Genera of Blosyrini

Abstract: A key to 10 genera of the Asiatic Blosyrini is given. A new genus, Blosyromimusgen. n. (Entiminae, Blosyrini) with 3 new subgenera (Blosyromimussubgen. n.,Eublosyromimussubgen. n., and Nanoblosyrussubgen. n.), is described from China. The new genus is characterized by the following features: the pronotum is widest somewhat distal to the middle, compressed laterally in the basal half, with numerous granules and with a distinct median carina on the disc; the sides of the elytra are beveled at the base, rarely somewhat rounded; the fore tibia of the male is not widened at the apex, the inner margin of the middle tibia is straight, not concave, with spines similar to those on the fore and hind tibiae; ventrite 5 of the male is with or without a shallow depression; apical margin of the ventrite is weakly excised so that, in ventral view, the outline of the abdominal apex is medially produced by the inner (dorsal) surface of the ventrite; the lamella of the penis is triangular or trapezoidal; the armament of the endophallus includes a pair of anterior sclerites and a pair of endophallic rods, without an unpaired median postostial grater, a pair of posterior sclerites, and paired clusters of spinules. Nine new species, Blosyromimus (Blosyromimus) alpinussp. n. (type species), B. (Blosyromimus) candidussp. n.,B. (Nanoblosyrus) griseussp. n.,B. (Eublosyromimus) lananicussp. n.,B. (Eublosyromimus) propriussp. n.,B. (Nanoblosyrus) parvulussp. n.,B. (Nanoblosyrus) pumiliosp. n.,B. (Blosyromimus) splendidulussp. n. and B. (Nanoblosyrus) pygmaeussp. n., are described and keyed. © 2022, Pleiades Publishing, Ltd.
