N e w r e c o r d s: CHINA: Gansu: Lenglong Ling Mts. , 80 km NNW Honggu, 37°03’47.0’’N 102°39’32.6’’E, 3439 m, 1.VII. 2011, M. Schülke leg., [CH 11-22], 1♀ ( MSC). Qinghai: Yunning Si (lamasery), 2890 m, 36°45.6’N 102°10.6’E, 1.-2.VII. 2005, J. Hájek, D. Král & J. Růžička leg., 1♀ ( ASC) ; Daban Shan , 25 km ESE Menyuan, 37°16’21.6’’N 101°52’37.4’’E, 2795 m, 6.VII.2011, M. Schülke leg., [ CH 11-22], 13, 1♀ ( ASC, MSC). Sichuan: Ganzi Tibet. Aut. Pref., Batang Co., Shalui Shan, 55 km NE Batang, 30°17’N 99° 31’E, 4300 m, 1.-3.VII.1999, D.W. Wrase, 13 ( MSC) .

C o m m e n t s: The female of the species was not known, the description therefore follows: first four segments of front tarsus considerably less dilated that those of male, segment 2 slightly narrower than apex of tibia. Genital segment with tergite 10 rather short and wide, markedly narrowed toward narrowly arcuate apex, sparingly setose as in Fig. 43 .

The specimens from Daban Shan were taken on loamy field edges; the specimen from Gansu was taken on alpine pasture by sifting litter under Rhododendron and azalea bushes, the specimen from Sichuan was taken in a meadow in a "pine-tree forest relict". This is the first record of the species from Gansu and Sichuan. It was previously known only from Qinghai and Tibet.
