( Figs. 7–9 , Plate A)

Description. Male: Body large size. Fastigium of vertex narrow, slightly wider than half the width of the 1st antennal segment, with a distinct longitudinal furrow above. Occiput with a weak longitudinal carina. Pronotum shouldered ( Fig. 7 ). Prosternum with 1 pair of slender, long spines. Meso- and metasterna lobate, the lobes of metasternum triangular ( Fig. 8 ). Tegmina and wings well developed, tegmina without stridulating organ. Fore coxa with 1 spine, fore femur with 4–5 spines on inner ventral margin only, fore tibia with 2 internal spines and 1 external spine above, and with 5 pairs of spines below, tympanal organ open. Middle coax with an acute angled denticle, middle femur with 5–6 spines on interno-ventral margin and 2–5 spines on extero-ventral margin, middle tibia with 4 external and 3 internal spines above, and with 5 pairs of spines below. Hind femur with 3–4 spines on interno-ventral margin and 8–11 spines on externo-ventral margin, hind tibia with 10 spines each margin above. Hind margin of ninth abdominal tergite depressed and with a protruding lobe each side, tenth abdominal tergite with 1 pair of hooks upcurved, Epiproct roundly triangular, paraproct nearly straight, longer than epiproct, tapering apically, far surpassing hind margin of subgenital plate. Cerci thin and long, distinctly longer than subgenital plate. Hind margin of subgenital plate with a U-shaped incision ( Fig. 9 ), styli longer, ventral surface grooved.
