Tegmen bearing an oblique vein and three chord veins, the third one and diagonal vein converge proximally. Dividing vein transverse and separating mirror as front and hind cells. Apical region degraded, lateral region bearing four Sc branches. Fore tibia only possessing external tympanum, elongate oval-like. Hind tibia bearing four dorsal spurs on two sides respectively, of the inside, first spur stubby and far away from others, and the basal of fourth one expanded; apical spurs three inside and outside respectively.
