Type material examined. Pൺඋൺඍඒඉൾ: CHNA: XංඇඃංൺඇǤ: 1 ♀, Tien Shan, Narat Mt Ridge (N slope), Syao-Jerglan River Basin, Tuyuk-Asha River combe, 12 km up stream of Chashi, 2600–2700 m a. s. l., in litter under Picea schrenkiana with withered Gramineae, 27.vii.2001, S. V. Saluk leg. (label written in Russian, VPSG).

Differential diagnosis. The species can be readily recognized from other brachypterous species of the group by distinct reticulation on head and pronotum, and by darker legs.

Redescription. Measurements. BL: 4.5 mm, FL: 2.0 mm. HW: 0.88 mm, PL: 0.64 mm, PW: 0.68 mm, EL: 0.81 mm, EW: 0.91 mm, SL: 0.62 mm. Head 0.97 times as wide as elytra; pronotum 0.93 times as long as wide; elytra 0.88 times as long as wide.

Male (based on the descriptions by Rඒඏĸංඇ 2003). Mesotibiae and metatibiae each with a tooth on inner side of apex; sternite VIII with triangular emargination in middle of posterior margin; sternite IX with distinct apicolateral projections, posterior margin serrate. Aedeagus (Rඒඏĸංඇ 2003: fig. 2) slender; apical sclerotized area of median lobe medium in length and pointed at tip; expulsion clasps slender, strongly sclerotized; copulatory tube long and broad; parameres much longer than median lobe, swollen in apical parts, each with two groups of setae on apico-internal margins: 7–11 setae in distal and 4 setae in basal group.

Female. Sternite VIII prominent in middle of posterior margin; spermatheca ( Fig. 22 View Figs 19–26 ) sclerotized with basal porch bilobed, spermatheca duct coiled at first bend, capsule small.
