Figure 8 Description. Male. Body medium. Head. Face ovoid; fastigium verticis about twice as wide as scape; fastigium frontis separated from fastigium verticis by a very fine suture ( Fig. 8A ). Median ocellus distinct. Thorax. Anterior margin of pronotum indistinct projecting in middle, posterior margin straight ( Fig. 8B ); lateral lobes longer than high, anterior angle widely arched, posterior angle rounded angular, humeral sinus shallow ( Fig. 8C ). Fore coxae with 1 small spine. Fore and middle femora unarmed; hind femora ventrally with 2–3 internal and 3–4 external spines. Fore and middle tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces, middle tibiae with 1 internal spur on dorsal surface. Hind tibiae dorsally with 3–5 internal and 5 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs. Wings small, laterad; tegmina scaly, apices obtuse; hind wings subtriangular. Abdomen. Second and third abdominal tergites each with 2 rows of few, very minute stridulatory pegs ( Fig. 8D ). Eighth abdominal tergite prolonged and down-curved ( Fig. 8F ). Ninth abdominal tergite globular, from about central area furrowed and later split along midline ( Fig. 8G ); on both sides of divided area semi-globularly swollen and terminating at ventro-internal angle into long, compressed spine with acute tip ( Fig. 8H ). Subgenital plate wider than long, with convex lateral margins, posterior margin triangularly concave, the lateral lobes rounded; styli long cylindrical, apices obtuse, inserted in about mid of plate length ( Fig. 8I ). Female. Unknown. Coloration. Body brown. Median ocellus yellowish brown. Pronotum with black margins. Ventral spines of fore and middle tibiae blackish, dorsal spines of hind tibiae black. Measurements (mm). Male: BL 21.85, PL 6.43, TL 2.18, HFL 12.4.
