Abstract

Brief morphological characteristics of the genera Blosyrus Schoenherr, 1823, Blosyrodes Jekel, 1875, and Blosyridius Fairmaire, 1891 are given. The new genus Stiltoblosyrus gen. n. (type species S. belousovi sp. n.) with 17 new species is described from Yunnan and Sichuan provinces of China. Stiltoblosyrus gen. n. is closely related to Blosyrodes but differs in the tuberculate pronotum and elytra, in the presence of an elongate process of the apex of the male hind tibia, in the armament of the endophallus consisting of tiny spicules, and in the usually hair-like vestiture of the body. The new genus includes S. andreii sp. n., S. asyae sp. n., S. belousovi sp. n. (type species), S. brevicornis sp. n., S. curvimanus sp. n., S. delavayi sp. n., S. fairmairei sp. n., S. gracilis sp. n., S. laticollis sp. n., S. kabaki sp. n., S. khalidi sp. n., S. lisu sp. n., S. longipes sp. n., S. pulcher sp. n., S. titanicus sp. n., S. vulgaris sp. n., and S. zhangi sp. n. A key to the 17 species is given. Most of the species were collected from Rhododendron at night time.

ACKNOWLEDGMENTS

I express sincere gratitude to my comrades I.A. Belousov and I.I. Kabak (All-Russian Institute of Plant Protection) who collected remarkable material of weevils in China and granted it to the ZIN collection. They consistently solved numerous organizational problems during our numerous expeditions. I am also grateful to B.A. Korotyaev (ZIN) for constant attention to the study and support.
