Taxonomic revision of the East Asian genus Scleropteroides Colonnelli, 1979 (Coleoptera,Curculionidae, Ceutorhynchinae)

The genus Scleropteroides Colonnelli, 1979 (Ceutorhynchinae: Scleropterini) was revised on the basis of detailed morphological observations. The genus was redefined to include three species from East Asia: S. hypocrita (Hustache, 1916) is redescribed and recorded from northeastern China and northern Korea for the first time; S. horridulus (Voss, 1958) is redescribed with new records from southern Korea; S. insularis Voss, 1971 was moved from synonymy with S. hypocrita to that with S. horridulus (syn. n.), and S. longiprocessus Huang & Yoshitake, sp. n. is described as new, sympatric with S. hypocrita in Japan. All the species are associated with woody Rubus species (Rosaceae). A key to species, habitus photographs, illustrations of important characters, and distribution maps are provided for each species.
