Description. Male (new description). Body medium. Face smooth with scattered impressed dots ( Fig. 1A View FIGURE 1 ). Eyes oval. Ocelli distinct. Fastigium verticis about two times as wide as scape.
Pronotum projected slightly in median area of anterior margin, posterior margin faintly concave; lateral lobes longer than high, ventral margin almost straight, humeral sinus indistinct ( Fig. 1B–C View FIGURE 1 ).
Fore coxae with 1 spine. Fore and middle femora unarmed on ventral surfaces, hind femora with 1–2 internal and 4 external spines on ventral surface. Fore and middle tibiae with 5 pairs of ventral spines, including 1 pair of apical ones; middle tibiae with 1 internal spine on dorsal surface; hind tibiae cylindrical with 4 internal and 4–5 external spines on dorsal surface, apices with 1 pair of dorsal spurs (the internal spur slightly longer than external one), 1 pair of subapical ventral spurs and 2 pairs of ventral spurs.
Wings small, positioned laterad, only reaching the middle area of mesonotum ( Fig. 1C View FIGURE 1 ); hind wings absent. Ninth abdominal tergite prolonged, and curved ventrad, posterior margin arched with 1 median concavity ( Fig. 1F View FIGURE 1 ). Tenth abdominal tergite with 1 pair of processes, suited on the concavity of ninth abdominal tergite; basal area of the processes depressed, crossed on each other, apical four-fifths area curved ventrad and slightly incurved, hook-shaped in apical view, apical area strongly sclerotised, apices acute. Cerci conical, directing dorsad and inwards ( Fig. 1G View FIGURE 1 ). Subgenital plate broader than long, basal margin semi-membranous, posterior margin with an obtusely triangular concavity, the lateral lobes obtuse ( Fig. 1H View FIGURE 1 ); styli inserted at apico-lateral angles of subgenital plate ( Fig. 1H View FIGURE 1 ).
Coloration. Body yellowish brown. Internal margin of antennal socket black, ventral margin with 1 longitudinal black stripe on each side, basal areas and apical areas of scape black, pedicel with black spots, flagellum black ( Fig. 1A View FIGURE 1 ). Fastigium verticis with 1 pair of black spots ( Fig. 1A View FIGURE 1 ). Dorsal surface of head with 1 pair of black spots at anterior area and 1 semicircular black stripe ( Fig. 1B View FIGURE 1 ). Pronotum with black margins, disc with 1 longitudinal black band along the midline which widened at anterior and posterior margins ( Fig. 1B View FIGURE 1 ). Mesonotum and metanotum with widely longitudinal black stripe along the midline, which widened at posterior margin ( Figs. 1B View FIGURE 1 , 2B View FIGURE 2 ). Fore coxae with black spine. Apical areas of all femora and tibiae brown. Tegmina black. Abdominal tergites black, sternites with blackish spots in middle area.
