Diagnosis. This new species is similar to C. sororius Liu & Shi , butdiffers from the latter by head with 5 lengthways yellow stripe in the occiput, and without any transverse yellow stripe in middle of dorsum and between lateral ocellus; supra anal plate distinctly narrowed posteriorly; posterior margin between lateral lobes of epiphallus distinctly narrowly rounded; female tegmina long and reaching 8th abdominal tergite. In the C. sororius Liu & Shi , head with a narrow transverse yellow stripe in middle of dorsum and between lateral ocellus respectively, and without lengthways yellow stripe in the occiput; supra anal plate slightly narrowed posteriorly; posterior margin between lateral lobes of epiphallus widely rounded; female tegmina short and reaching 5th abdominal tergite.

Description. Male ( Fig. 1 ). Body small-sized. Head nearly teardrop-shaped ( Fig. 3 ), slightly wider than anterior margin of pronotum, frontal rostrum short and about 2.1 times as wide as scapus; eyes large, oval; median ocellus sunken and semilunar; last joint of maxillary palpus slightly longer than 4th joint, distinctly widened apicad. Pronotum transverse, slightly widened posteriorly, about 0.6 times as long as width of posterior margin, anterior and posterior margins straight. Tegmina reaching abdominal apex, present with 3 oblique veins, mirror large, about 1.4 times as long as wide. Fore tibia with a small and oblong internal tympanum. Hind femur slender, about 4.2 times as long as maximal width; hind tibia with 4 pairs of dorsal spines and 2 pairs of apical spurs, of which middle one longest while lower one shortest among the inner spurs, lower and upper ones equal in length and distinctly shorter than middle one among outer spurs; first hind tarsal segment lateral side with 8 and inboard side with 7 small spines in a line on dorsal surface.

Supra anal plate ( Fig. 5 ) distinctly narrowed posteriorly, with posterior margin narrow and rounded at apex. Subgenital plate rather long, narrowed posteriorly, turn the left and right margins curl inwards, nearly coniform. Genitalia ( Figs 7–9 ): epiphallus with two lateral lobes on posterior margin, and posterior margin between lateral lobes of epiphallus distinctly narrowly rounded; lateral lobes acute at apex and bent upwards apicad in lateral view.

Female ( Fig.2 ). Head very similar to that of male ( Fig. 4 ). Lateral margins of pronotum nearly parallel. Tegmina reaching 8th abdominal tergite, present with several parallel veins. Ovipositor straight, spear-shaped, 0.17 times shorter than hind femur.

Coloration. Body black brown. Head black, with 5 lengthways yellow stripe in the occiput of head, mouthparts light tawny. Pronotum black, with some light yellow markings. Legs yellowish brown mixed with irregular dark brown markings, hind femur with numerous yellow markings on outer surface. Ovipositor brown.

Measurements (mm). Male: body 7.0–9.0, pronotum 1.8–2.0, tegmen 4.0–5.5, hind femur 4.0–6.0; female: body 8.2–9.5, pronotum: 2.0–2.1, tegmen 3.2–5.5, hind femur 5.5–6.2, ovipositor 4.5–5.5.

Distribution. China (Xizang).

Etymology. The specific name is derived from the type locality Yigong ( China: Xizang: Bomi).
