Hind femora beneath with 5–6 inter spines and without outer spines; hind tibia above with 24–31 outer spines and 24–27 inter spines, inner subapical spur of hind tibia longer than hind metatarsus. Hind metatarsus with 2 dorsal spines. Apex of paraproct blunt and curved upwards ( Fig. 11 ). Process of 7th abdominal tergite with a distinct incision ( Fig. 12 ). Male genitalia with a distinct notch at the apex of dorso-median lobe and lateral lobes quite long ( Fig. 13 ).

Female. Subgenital plate nearly triangular, both sides of basal part prominent and apex blunt ( Fig. 14 ). Ovipositor longer than the half of hind femora.

Measurements. (length in mm) Body Ƌ15.0, ♀14.0; pronotum Ƌ5.0, ♀5.0; fore femora Ƌ11.0, ♀12.0; hind femora Ƌ20.0, ♀20.0; hind tibia Ƌ23.0, ♀24.0; ovipositor 16.0.

Material examined. Holotype, 1♂, Bomi, Tibet, alt. 2080m, 2010. VII.14, collected by Bi Wen-Xuan et al.; paratype, 1♀, Hanmi, Tibet, alt. 2100m, 2011. VII.23–VIII.7, collected by Bi Wen-Xuan.
