Abstract: The glabripennis species group of Anoplophora includes five species in China: a species in Taiwan and 4 species in mainland. They are: A. Flavomaculata(Gressitt), A. glabripennis (Motschulsky), A. nobilis (Ganglbauer), A. freyi (Breun-ing) and A. coeruleoantennatus (Breuning). The first one, a Taiwan species is not available to the authors, and the last one is a suspectable species, it is perhaps merely individual variation. This paper deals with the taxonomic characteristics of anatomy with the genitalia,host, distribution, origin and evolution of the group. A.Glabripennis (Motschulsky) is distributed mainly over Shanxi Province and the plateau of eastern Shanxi, its primary host being Populus, Salix, ulmus and Acer. A.Nobilis (Ganglbauer) is distributed mainly over Gansu, Ningxia and Shaanxi Provinces,north to the Qinling Mountains, its primary host being Populus. A. freyi (Breuning) is distributed mainly over Yunnan, Sichuan and Guizhou Provinces, south of Qinling Mountains, its primary host being Salix, but A. nobilis (Ganglbauer) and A. glabripen-his (Motschuksky) are not found in this region. The ranges of distribution of these three species overlap in Shanxi and (or)Shaanxi, about north of Qinling mountains.
