Material examined. Malaysia: Selangor, Ulu Gombak Field Study Centre, 20 km NW Kuala Lumpur, (3°20'N, 101°45'E), 8.iii.1991, leg. D. Kovac— 1 male (Frankfurt SMF) .

Description. Small to medium sized species. Head: Face rather narrow; forehead nearly smooth; fastigium verticis about as wide as scapus; small ocelli hardly distinct (Fig. 83F). Abdominal tergites two and three each with two rows of stridulatory pegs (6, 17; 16, 16; n = 1; Fig. 84H).

Wings very long, largely surpassing body and little surpassing tip of stretched hind tibia (Fig. 82K). Tegmen: Radius releases RS only in about apical third; both veins branched near tip; media anterior free from base, but in basal area closely approached to R; single-branched; cubitus anterior at base with a single branch that forks into two veins in about basal third, the anterior branch divides again into two branches, MP and CuA1, while the posterior branch (CuA2) does not divide further; cubitus posterior undivided, free throughout; with 4 anal veins, the last incomplete.

Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 8–9 external and 11–13 internal spines on ventral margins, increasing in size towards posterior end; hind tibia with few small spaced spines on both dorsal margins increasing in size from base to end, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides (Fig. 82L).

Coloration. General color uniformly pale brown (originally conserved in alcohol). Face yellowish brown. Tegmen yellowish transparent, veins yellow; hind wing transparent.

Male. Eighth abdominal tergite prolonged. Ninth abdominal tergite largely vertical, vaulted, with distinctly converging lateral margins, apex in middle a little roundly projecting. Tenth abdominal tergite rather large, transverse, with a transverse furrow, interrupted in middle, in situ little hidden between ninth tergite and subgenital plate; at apical margin with a pair of black hooks curved laterad and in situ hidden by subgenital plate (Fig. 83G). Subgenital plate without styli; with swollen basal area and convex and upcurved lateral margins; apical margin slightly bilobate (Fig. 83H). Phallus membranous.

Female. See Gorochov (2005).
