(Figs. 20–24, Plate E)

Description. Male: Body medium size. Pronotum shouldered. Prosternum with 1 pair of slender, long spines. Meso- and metasterna lobate, the lobes of metasternum triangular with apex pointed (Fig. 20). Tegmina and wings well developed. Tegmina exceeding apex of hind femur, hind wings nearly equal to tegmina. Fore coxa with 1 spine, interno-ventral margin of fore femur with 2 spines, but externo-ventral margin without spine, knee lobe with 1 spine, fore tibia with 2 internal spines and 1 external spine above, with 5 pairs of spines below, tympanal organ open. Middle femur unarmed below, middle tibia with 4 external and 3 internal spines above, with 5 pairs of spines below. Both ventral margins of hind femur with 3–4 spines, hind tibia with 9–10 spines each margin above. Hind margin of ninth abdominal tergite with 1 pair of processes, wrinkled above. Tenth abdominal tergite with 1 pair of hooks upcurved (Figs. 21–22). Epiproct roundly triangular, paraproct tapering apically, slightly exceeding hind margin of subgenital plate, with apex acute and strongly diverged. Cerci thin and long, distinctly longer than subgenital plate. Lateral margin of subgenital plate parallel in apical half, hind margin of subgenital plate truncate (Fig. 23).

Female: Body roughly similar to that of male. Subgenital plate protractedly triangular with pointed apex (Fig. 24). Ovipositor upcurved in apical half, with apex obtuse.

Coloration. Body dark grayish brown, with pale yellowish spots. Antennae dark brown, with light rings. Legs light brown, with darkish stripes, hind femur with an interrupted longitudinal blackish stripe in outer side. Fore wings brown, transparent, with dark stripes. Cerci lightish brown.

Measurements (length in mm). Body ♂ 23.0–25.0, ♀ 25.0–27.0; pronotum ♂ 5.5–6.0, ♀ 6.0 –6.5; tegmina ♂ 27.0–30.0, ♀ 24.0–26.0; hind femur ♂ 24.0–27.0, ♀ 25.0–26.0; ovipositor ♀ 16.0–18.0.

Material examined. Holotype 1 ♂, Hanmi, Xizang, Alt. 2100m, 2011. VII.23–VIII.7, leg. Bi Wen-Xuan; paratype 2 ♂♂, 10 ♀♀, same data as holotype.

Distribution. China (Xizang).
