Body size: medium, 37–39 mm (male); 39–40 mm (female).

Head: In dorsal view, almost triangular, slightly longer in midline than wide about (c.1:0.6), shorter than pronotum in length about (c.1:1.5), head slightly narrower than pronotum about (c.1:1.4), median length of fastigium as long as width, vertex longer than fastigium about (c.1:0.7); dorsal width of fastigium 1.5 times wider than antennal scape; compound eyes spherical, prominent. In lateral view, fastigium without ventral carina, strongly elongate, rather blunted at the tip; notch between fastigium and frons deep, distance between opening 2 times shorter than depth, basal process slightly produced, apical process absent. In anterior view, antenna scape narrower than antenna socket 1: 1.8; lateral margins of frons parallel and apical part slightly divergent; face wider than width at level of eye about 1:0.8.

Thorax: Pronotum without lateral carinae; in lateral view, dorsal and ventral margin straight, median height 2 times shorter than median length, with a marked invagination at the posterior margin; in dorsal view, narrower anteriorly slightly convergent towards head. Prosternum with a pair of spines, hind femora with ventral spines, hind femur length three times longer than mid femur. Tegmina covering abdomen, and in female to tip of ovipositor, male stridulatory rib characteristic with narrow teeth present; male mirror of the right tegmen oval with a stridulatory file.

Genitalia: Ovipositor straight, slender and narrowing towards the apex, usually as long as hind femur. Cerci cylindrical, last segment with a process perpendicular to segment, and inwardly bent towards midline. Tenth tergite rather concave with short styli, not projecting beyond cerci.
