The type specimens are deposited in the Department of Entomology of China Agricultural University, Beijing, China.1 Atkinsoniella nigriscens sp.nov.(Figs.1-8) Length(Incl.tegm.):♂9.5mm, ♀8.0-8.5mm. This species can be separated from other species of the genus by its body obviously larger in male than in female, male paraphysis divided into two branches at middle and jointing with aedeagus by the two branches clipping it, and the unique shape of pygofer process. Holotype♂, Xizang, Chayu, Dongku(1570m, 28°2′N,97°7′E), 30 June 1978, coll. LI Fa-Sheng. Paratypes 4♀♀, 29 July to 1 Aug. 1978, 2♀♀, 15 June 1978, Xizang: Yigong(2300m, 29°43′N, 94°10′E), coll. LI Fa-Sheng; 1♀, Xizang: Tongmai(2050m, 29°22′N,95°4′E), 27 July 1978, coll. LI Fa-Sheng.2 Atkinsoniella fuscopenna sp.nov.(Figs.9-14) Length(Incl.tegm.):♂7.3-7.5mm, ♀7.6-7.8mm. This species is related to A. nigrosteaka Li et Wang in appearance, but differs in body larger, maculae and stripes on head and thorax brown or yellow, fore wing brown without a black longitudinal stripe in middle of corium, and the shapes of male pygofer, pygofer process and aedeagus. Holotype♂, Xizang: Zamu (2700m, 29°10′N,95°41′E), 21 July 1978, coll. LI Fa-Sheng. Paratypes: 1♀, same data as holotype; 2♀♀, Xizang: Zamu (2700m), 8 July 1978, coll. LI Fa-Sheng; 1♂, Xizang: Yigong(2300m, 29°43′N,94°10′E), 15 June 1978, coll. LI Fa-Sheng.3 Atkinsoniella brevistyla sp.nov.(Figs.15-20) Length(Incl.tegm.):♂7.7-7.9mm, ♀8.0-8.2mm. This species is allied to A. angula Kuoh, but can be easily distinguished from the latter by the body lar- ger, face with a U-shaped black streak, scutellum with a red spot at base, male style only slightly extending posteriorly beyond connective apex, and the shapes of male pygofer process, aedeagus and paraphysis. Holotype♂, Xizang, Yigong(2300m, 29
