Material examined. 1♂, CHINA, Xinjiang Uygur Autonomous Region, Ili Kazak Autonomous Prefecture, Huocheng County , Near Railway Station , 44°3′39.6″N, 80°50′24″E, 624 m, 26. VII .2019, Qian Han ( CNU) .

Diagnosis. Male ( Fig. 51 ). Clypeus wholly with sparse punctures; vertex ( Fig. 52 ) with shallow and moderate to sparse punctures, POD 0.8× OOD; pronotal anterior carina ( Fig. 53 ) completely present, dorsum of pronotum sparsely punctate; lateral side of pronotum ( Fig. 54 ) wholly densely punctate and without striae; dorsum of propodeum ( Fig. 55 ) densely punctate and medially with depression; ventral surface of mid femur with more or less sparse punctures and setae; T1 apically with yellowish band; T2–T5 ( Fig. 51 ) apically with three yellowish spots (interrupted band), one on lateral side and one on elongated median; T6 apically with yellowish spots or apex yellowish; basal two-thirds of T3–T5 with moderate punctures, and apical one-third smooth and impunctate; T7 ( Fig. 56 ) anteriorly with dense to moderate punctures and posteriorly with very sparse punctures, apex with deep notch, tipped lobes rounded.

Female. Head square, as high as wide in frontal view, elongated behind the eyes; anterior margin of clypeal straight; pronotum dark red and sub trapezoidal, posterior width 1.6× length of anterior to posterior margin, and a bit elongated (1.4×); dorsum of propodeum laterally and upper portion of side with dense striae, medially largely smooth; T1 subapically without a row of punctures forming groove; each of T2–T5 subapically with a row of punctures and medially absent forming incomplete groove; lateral surface of T2–T3 or T2–T4 with small yellowish spots, the distance between two lateral spots more than the length of the spot. No female specimens were collected in our study, so the description is referred to Guiglia (1961) and Boni Bartalucci (2011a).
