A New Weevil Genus Closely Related to Dactylotinus Korotyaev, 1996 (Coleoptera, Curculionidae: Entiminae) with New Species from the Sino-Tibetan Mountains

摘要

Abstract A new weevil genus, Eudactylotinusgen. n. closely related to Dactylotinus Korotyaev, 1996 (Entiminae, Blosyrini), is described from China. It differs from Dactylotinus in the following features: the pronotum is widest somewhat distal to the middle, compressed laterally in the basal half, with numerous granules and distinct median carina on the disc; the humeri are slanting, rarely rounded; the male fore tibia is not widened at the apex; the inner margin of the middle tibia is not concave, with spines similar to those on the fore and hind tibiae; the armament of the endophallus usually has no unpaired median postostial grater (MPG) and a pair of spinule clusters (PCS). Five new species are described: Eudactylotinus shangrilensissp. n. (type species), Eu. muliensissp. n.,Eu. premucronatussp. n.,Eu. silvestrissp. n., and Eu. squamulatussp. n. A key to the five species is given.
