First to fourth abdominal tergites with fine stridulatory pegs ( Fig. 4E ). Posterior margin of tenth abdominal tergite straight. Cerci conical, apices acute and upcurved ( Fig. 4I ). Basal area of subgenital plate triangular, lateral margins of middle areas contracted and terminating into a short spiniform apical area; basal area about 1.7 times as long as apical spine. Ovipositor upcurved, basal area stout, basal two fifths straight, the other parts upcurved, apices acute, dorsal valvulae significantly longer than the ventral one ( Fig. 4H–I ). Male. Unknown. Coloration. Fastigium verticis, disc of pronotum and apices of femora black with yellow spots. Face brown with black spots ( Fig. 4A ). Disc of pronotum with large yellow spots on both sides, anterior area with a heart-shaped yellow spot in middle ( Fig. 4B ). Ventral surface of thoracic sternites yellow, abdominal tergites with yellow and black spots ( Fig. 4D, K ). Ocelli yellow. Measurements (mm). Female: BL 35.1, PL 9.1, HTL 30.2, HFL 29.4, OvL 14.4.

Figures 1–4 Description. Male (new description). Body medium, coloration is very similar to female, wings absent. Head. Fastigium verticis depressed, projecting forward, dorsal surface with indistinct median furrow ( Fig. 1B ). Ocelli distinct; lateral ocelli located on both sides of fastigium verticis, slightly larger than median ocellus. Eyes oval, projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices faintly swollen ( Fig. 1A ). Thorax. Disc of pronotum smooth, anterior and posterior margins nearly straight; lateral lobes longer than high, ventral margin widely arched ( Fig. 1D ). Prosternal lobes spine-shaped with basal areas separated from each other ( Fig. 1C ); mesosternal lobes with basal half convex on both margins, after middle area terminating into a spine, its apices obtuse ( Fig. 1C ); metasternum with 1 pair of obtusely triangular processes, basal areas separated, internal and external margins obliquely straight and converging, apices obtuse ( Fig. 1C ). Legs. Fore coxae with 1 stout spine; genicular lobes of femora obtuse; tibiae with 2 internal spurs and 1 external spur on dorsal surface, ventral surface with 4 pairs of spurs and 1 pair of apical spurs; basal areas of tibiae with 1 pair of oval tympana, the internal tympanum ( Fig. 1E ) slightly larger than external one ( Fig. 1E, F ). Middle coxae with 1 depressed spine; femora unarmed; dorsal surface of tibiae with 4 internal spurs and 3 external spurs, ventral surface with 4 pairs of spurs and 1 pair of apical spurs. Ventral surface of hind femora with 2 internal spines, genicular lobes with 1 internal spine ( Fig. 1G ); dorsal surface of tibiae with 9 pairs of spines and 1 pair of subapical spurs (the internal one longer than external one), ventral surface with 2 internal spurs, 1 external spur and 1 pair of long subapical spurs, apices ventrally with 1 pair of long and 1 pair of short spurs. Abdomen. First to fourth abdominal tergites with stridulatory pegs ( Fig. 1I ). Posterior margin of ninth abdominal tergite almost straight with 1 dactylitic lobe on each side; posterior margin of tenth abdominal tergite arced concave with 1 pair of sclerotized hooks widely separated which upturned over the lobes of ninth abdominal tergite, its apices directing forwards ( Fig. 2E ). Cerci conical. Paraproctal processes about as long as cerci, lateral margins of basal areas obliquely narrowing and upcurved behind base ( Fig. 2D ); apical third area depressed, apical margins concave with a long oblique-triangular projection on dorso-apical margin, ventro-apical angle rounded ( Fig. 2G ). Subgenital plate longer than paraproctal processes; basal third swollen with convex and approaching lateral margins ( Fig. 2I ); in apical two-thirds with 1 pair of subparallel lateral carinae on ventral surface, between them concave along the midline; posterior margin straight ( Fig. 2I ). Styli subcylindrical, inserted at the apical angles of subgenital plate ( Fig. 2I ). Measurements (mm). Male: BL 24.3–24.6, PL 7.1–7.3, HFL 20.4–20.9.
