Description. Female. Head. Fastigium verticis conical, dorsal surface with a distinct median sulcus. Eyes nearly subglobal, protruding outwards ( Fig. 6 View FIGURE 6 A). Apical segment of maxillary palpi slightly longer than subapical one, apex inflated.

Thorax. Pronotum with anterior margin almost straight, posterior margin obtusely rounded ( Fig. 6 View FIGURE 6 A); lateral lobe longer than high, ventral margin undulating, posterior margin with humeral sinus distinct ( Fig. 6 View FIGURE 6 B).

Legs. All femora unarmed on ventral surface. Procoxae with a short spine. Pro- and mesotibiae with 4 pairs of minute spines on ventral surface and a pair of apical spines; tibial tympana opened on both sides, inner one slightly larger than outer one. Posttibiae with 21–22 inner and 21 outer spines on dorsal surface, ventral surface with 5–6 minute outer spines, apices with 1 pair of dorsal and 2 pairs of ventral spurs.

Wings. Tegmina just reaching apices of posttibiae; apices obliquely rounded. Hind wings slightly longer than tegmina, surpassing apices of posttibiae.

Abdomen. Posterior margin of tenth abdominal tergite with a triangular concavity in the middle. Epiproct ligulate. Cerci conical, curved upwards, their apices acute. Subgenital plate nearly trapezoidal, longer than broad, basal area broad, narrowing, posterior margin almost straight, centre of which slightly concave ( Fig. 6 View FIGURE 6 D). Twothirds basal area of ovipositor almost straight, the other area slightly upcurved; dorsal and ventral margins smooth, apices of dorsal valvulae acute, ventral ones with a terminal hook separately ( Fig. 6 View FIGURE 6 C).

Coloration. Body yellowish green, alive green ( Fig. 7). Eyes brown. Fastigium verticis black, occiput with 1 longitudinal light brown stripe, which extending to disc of pronotum. Anterior margins of pronotum and metazona with 1 pair of black spots separately.

Distribution. China (Xizang).

Measurements (mm). BL: ♂ 8.220–9.208, ♀ 9.870–11.600; PL: ♂ 3.230–3.577, ♀ 2.982–3.346; PFL: ♂ 7.739–7.849, ♀ 8.637–8.954; TL: ♂ 14.827–16.261, ♀ 16.419–18.132; Ov: 7.583–9.297.

Remarks. This species is only known from the type locality and similar to Nigrimacula quadrinotata (Bey- Bienko, 1971) com. nov., but differs in the shape of male cerci and subgenital plate of both sexes. The detailed differences have been present in the key.
