Description. Male. Body small sized, slender. Head broadly oval, fastigium of vertex about 2 times as broad as scape. Fore margin of pronotum slightly convex, hind margin straight. Tegmina rather exceeded beyond apex of hind femur; R vein with 4 branches, Rs arising from R vein nearly in the middle, with 3 branches; M vein simple, Cu1 vein with 3 branches ( Fig. 5 ); A vein with 4 branches. Wings slightly extending beyond tegmina. Hind femur with 4–6 inter spines and outer spines on ventral surface; hind tibia on dorsal surface with 5–6 outer spines and 3– 5 inter spines. Hind margin of male 10th abdominal tergite bearing 2 spines ( Fig. 6 ), with pairs of spine-like processes on ventral surface. Subgenital plate divided into two lobes, apical half of lobes strongly incurved and hairy, with obtuse apex ( Fig. 7 ). Styli situated in the base of subgenital plate, cylindrical.
