A taxonomic study of Eastern Palaearctic Omiini (Coleoptera: Curculionidae: Entiminae).

A new monotypic genus, Yunakovius gen. nov., is described, based on Y. orientalis sp. nov. from China, Mongolia and Siberia. The genus Omo iotus Sharp, 1896 is recognized as a junior synonym of Asphalmus Sharp, 1896, which currently contains three species: Asphalmus japonicus Sharp, 1896, A. ovatus (Sharp, 1896), comb. nov., and A. sharpi sp. nov. (China). A lectotype is designated for Omoiotus ovatus Sharp, 1896. A key to Asphalmus species is given, the three species included are redescribed and illustrated, including male and female genitalia. [ABSTRACT FROM AUTHOR]
