Redescription. – Male. Size a little larger than the former two species. Hind wing conspicuously longer than tegmen. Stridulatory file rather straight, circa 2/5 at base comparatively thick, middle 2/5 rather thin, and then becoming thicker toward apex; and with narrowly spaced fine teeth in 4/5 area from base as well as 10 widely spaced thick teeth in 1/5 apical area (Figs. 3, 8, 11). The whole area of the stridulatory apparatus of right tegmen bigger, its scraper cambered, comparatively narrow area situated more distally than main structure of the stridulatory apparatus, and proximal area between MA and MP+ CuIA, semi-transparent with a few veinlets (Fig. 14). The 10 th abdominal tergite slightly depressed, lightly prolonged backwards, with hind margin truncate. Supra-anal plate approximately rectangular. Cerci very broad at basal 1/3, then sharply acuminate, yataghanshaped. The subgenital plate with the broadest base, then becoming narrower, split for almost apical 3/5, upcurved.

Female similar to male. Supra-anal plate triangular; Cerci rather short, conical; ovipositor fairly narrow and short, upcurved, both margins denticulate (Fig. 25); Subgenital plate triangular, apex obtuse-round (Fig. 28).

Measurements (length in mm). – body: male 16.5, female 19.5; pronotum: male 4.0, female 4.1; tegmen: male 25, female 24; width of tegmen: male 6.5, female 3.5; hind wing: male 31.5, female 26; hind femur: male 19.5; female 20.5; ovipositor: 5.0.

Variation. – One male specimen from Guangxi Prov. is distinctly larger than others [Measurements (length in mm). – body 18.5; pronotom 4.0; tegmen 30.0; width of tegmen 6.5; hind wing 38.0; hind femur 25.0]. Its stridulatory file was contaminated and no drawing can be obtained, so we put it in this species.

Distribution. – Kashmir, Thailand, Burma and China.
