Lateral keels in prozona slightly contracted backward, humeral angle widely rounded, with a pair short longitudinal keels between shoulder, caudal end of pronotum narrow, long cone-shaped, surpassing the top of hind femora distinctly, length of hind process which surpassing behind top of hind femur about 3.0 mm. Lateral lobes of pronotum turning outwardly, posterior angles directed distinctly backwards, apex of posterior angles strident, posterior margin of each lateral lobe with two bisinuate. Tegmina long, ovate, apex narrowly rounded. Hind wings reaching the top of hind process. Upper and lower margins of fore and middle femora straight, the width of tegmina 1.2 times wider than width of midfemur, length of hind femur 3.1 times its width, genicular denticles right angle. Outer side of hind tibia with 8 spines, inner side with 7 spines. Length of first segment of hind tarsus longer than third.
