Figure 3 Description. Male. Body large. Face almost smooth with scattered impressed dots; fastigium frontis separated from fastigium verticis by a very fine suture ( Fig. 3A ). Ocelli distinct, median ocellus slightly larger than lateral ocelli ( Fig. 3A ). Anterior margin of pronotum faintly projecting, posterior margin arched ( Fig. 3B ); lateral lobes longer than high, with deep V-shaped furrow ( Fig. 3C ). Fore coxae with 1 small spine; fore and middle femora unarmed, tibiae ventrally with 4 pairs of spurs and 1 pair of apical spurs. Hind femora with 7 – 11 internal and 5 – 7 external spines on ventral surface; dorsal surface of tibiae with 5 – 6 internal and 6 – 7 external spines and 1 pair of apical spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs. Wings developed, reaching the middle area of hind tibiae. Second and third abdominal tergites with fine stridulatory pegs ( Fig. 3D ). Eighth abdominal tergite prolonged backward and a little ventrad. Ninth abdominal tergite furrowed in the midline, the lateral sides faintly convex that terminate at ventro-internal angle into a large compressed sickle-shaped process with serrate apical margin ( Fig. 3G ). Subgenital plate about two times as wide as long, ventral surface with median furrow, posterior margin faintly concave ( Fig. 3I ). Styli cylindrical, gradually upcurved in lateral view, apices obtuse; inserted at apico-lateral margins of subgenital plate ( Fig. 3I ). Female. Unknown. Coloration. Body yellowish brown. Eyes brown. Ocelli pale yellow, medium ocellus surrounding purpureal pattern. Genae black ( Fig. 3A ). Internal margins of antennal sockets black, scape and external margins of pedicel black. Dorsal surface of head black. Pronotum with wide black margins which widened at anterior and posterior margins, the anterior margin surrounding an arched yellow-brown spot on each side ( Fig. 3B, C ). Apical areas of all femora black, basal and apical areas of all tibiae black. All spines of all tibiae black. Tegmina with brown veins. Measurements (mm). Male: BL 31.54–33.53, PL 7.14–7.98, HFL 19.73–20.04, TL 29.12–31.42.
