Gaurotina nigroantenata, sp. nov. (Figs.1,2) Body length: 15.5 mm～18.0 mm; width: 6.5 mm～7.0 mm. This new species is close to Gaurotina superba Ganglbauer, differing in head and antennae entirely black; and the legs ochraceus black instead of yellowish brown; prothoracic lateral teeth similar in shape instead of one is smaller than the other; and the intercoxal process of mesosternum thick , short and cylindrical instead of slender and acute. Holotype ♀, Tianjin (Tuweiba River), 11-Ⅶ-1956; Paratype ♀, Jilin (Linjiang), Ⅶ-1956. 2. Rhagium qinghaiensis, sp. nov. (Figs.3～5) Body length: 18.0 mm; width: 6.0 mm. This new species can be distinguished from Rhagium inquisitor L.; R. japonicum Hayashi and R. rugipenne Reitter by the presence of thick hair on the body, genae very long and hind femora exceeding the apex of abdomen. Holotype ♂, Qinghai (Zeku), 1-Ⅵ-1975, Ma Jiyuan coll. 3. Sinostrangalis simianshana, sp. nov. (Figs.6～10) Body length: 11.0 mm～14.0 mm; width: 3.0 mm～4.5 mm. The female of this new species differs from S. yamasakii (Mitono) from Wuyi Shan, Fujian Province in the body largely reddish brown, the metaepisternum reddish brown, only blackened at edge instead of entirely black. The male differs from S. basiplicatus (Fairmaire) in two short transverse spots on the middle of the elytra instead of a semi circular spot open externally; antennae shorter than instead of longer than elytral apices. Holotype ♀, Chongqing (Jiangjin, Simian Shan), 27-Ⅶ-1991, Xiao Chonggang coll., Paratypes 3♂♂, 1♀, Chongqing (Jiangjin, Simian Shan), 27-Ⅶ-1991, Yin Youping coll., Guangxi (Longsheng County), 24-Ⅵ-1982, Wang Xinli coll., Guizhou (Fanjing Shan).更多还原
