Specimens examined. Holotype: female, Zham, Nyalam, Xizang, China, 22 August, 2014, coll. by Guanglin Xie. Paratypes: 1 female, Zham, Nyalam, Xizang, China, 22 August, 2014, coll. by Guanglin Xie; 1 male and 1 female, Zham, Nyalam, Xizang, China, 24 August, 2014, coll. by Guanglin Xie.
Description. Female. Head. Fastigium verticis conical, dorsal surface with a deep median sulcus ( Fig. 1 View FIGURE 1 G). Eyes nearly global, protruding forwards. Apical segment of maxillary palpi as long as subapical one, apex inflated.
Thorax. Pronotum with anterior margin almost straight, posterior margin slightly rounded ( Fig. 1 View FIGURE 1 H); lateral lobe longer than high, ventral margin undulating, posterior margin with humeral sinus distinct ( Fig. 1 View FIGURE 1 G).
Legs. All femora unarmed on ventral surface. Procoxae with a short spine. Pro- and mesotibiae with 4 pairs of minute spines along both sides of ventral surface, apices with a minute spine on each side. Posttibiae with 25–26 minute spines on internal margin of dorsal surface, external margin with 24–28 spines, apex with 1 pair of spurs; ventral surface with 3–4 minute spines on external margin, apex with 2 pairs of spurs on each side.
Wings. Tegmina surpassing apices of posttibiae; apices obliquely rounded, anterior margin weakly produced, posterior margin straight. Hind wings slightly longer than tegmina.
Abdomen. Posterior margin of tenth abdominal tergite with a median concavity. Epiproct ligulate. Cerci conical, apices acute. Subgenital plate nearly hexagonal, about as broad as long, lateral margin of basal half nearly straight, apical half slightly narrowing, oblique, posterior margin almost straight and with a shallow concavity in the middle ( Fig. 1 View FIGURE 1 I). Basal half of ovipositor straight, apical half slightly upcurved; dorsal and ventral margins smooth, dorsal valvulae slightly longer than ventral ones, its apices acute, while apices of ventral valvulae with a hook separately ( Fig. 1 View FIGURE 1 J).
Male. Differs in slightly shorter size and following characters: posterior margin of tenth abdominal tergite with a median concavity ( Figs. 1 View FIGURE 1 C, E; 2A). Cerci stout, internal margin expanded, apices with 2 triangular spines ( Figs. 1 View FIGURE 1 C; 2B). Subgenital plate longer than broad, posterior margin projected; styli conical, apices obtuse, located on ventral margin of subapex ( Figs. 1 View FIGURE 1 F; 2C).
Coloration. Body yellowish green (probably light green when alive). Eyes brown. Fastigium verticis black brown, occiput with 1 longitudinal light brown stripe, which extending to anterior area of metazona along the midline ( Fig. 1 View FIGURE 1 A, G). Anterior margin of pronotum with 1 pair of black spots ( Fig. 1 View FIGURE 1 G), while these spots for some specimens very small and indistinct ( Fig. 1 View FIGURE 1 G).
Measurements (mm). BL: ♂ 7.275, ♀ 8.410–11.022; PL: ♂ 3.246, ♀ 2.293–3.302; PFL: ♂ 7.0 79, ♀ 8.336–8.341; TL: ♂ 15.0 37, ♀ 17.250–18.006; Ov: 9.358–9.974.
Distribution. China (Xizang).
Remarks. This species can be distinguished from the others of the genus in: anterior margin of pronotum with 1 pair of black spots; apical area of male cerci with 2 triangular spines; female subgenital plate nearly hexagonal, posterior margin slightly concave in the middle.
Etymology. The new species name is derived from the pronotum with 1 pair of black brown spots on anterior margin.
