Description. Large species ( Fig. 4I ). Head: Face ovoid; fastigium verticis about twice as wide as scapus; ocelli indistinct; fastigium frontis separated from fastigium verticis by a very fine suture; a pair of weak sub-antennal furrows, starting at internal angles of antennal scrobae, separate the central area of face from lateral areas and fuses ventrally with clypeo-frontal suture, clypeo-frontal suture interrupted in middle; subocular furrows present ( Fig. 5F ). Pronotum at lateral and anterior areas of rim with fine granules. Abdominal tergites two and three with a single row of 7 minute stridulatory pegs along hind margin of third tergite. Wings reaching about tip of stretched hind tibiae. Tegmen ( Fig. 9E ): Radius with two branches, both forked near tip; media anterior fused in basal area with radius; media posterior absent; cubitus anterior forks before midlength into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 5 anal veins. Legs: Fore coxa with a rather large spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large, on mid tibiae comparatively short, ventral spines and one pair of smaller ventral spurs; hind femur with 8 external and 7 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides. Coloration. General color light brown (originally conserved in alcohol); vertex unicolored; disc of pronotum unicolored, hind margin hardly darker. Legs of general color. Face unicolored; only clypeo-frontal suture and lateral margin and tip of mandibles black. Tegmen semi-transparent whitish with hardly darker yellowish veins; hind wing anterior area as fore wing, otherwise medium to dark brown contrasting with cross-veins and surrounding areas light yellowish brown. Male. Ninth abdominal tergite semi-globular: prolonged and down-curved laterally and apically; before apex furrowed and narrowly split in midline with resulting margins granular; apical margin with a fine styliform projection on both sides of split area projecting mediad. Tenth abdominal tergite narrow, band-shaped, interrupted in middle ( Figs. 6 J–K). Epiproct distinct. Subgenital plate almost twice as wide as long, shallowly and widely grooved in apical half; apical margin wide obtuse-triangularly excised; styli inserted laterally at apical margin ( Fig. 6K ). Phallus membranous. Female see Karny (1923) . Measurements ( 1 male ).—body w/wings: 50; body w/o wings: 35; pronotum: 8; tegmen: 37; tegmen width: 13; hind femur: 18 mm .
