Description. Small to medium sized species. Head: Face narrow ovoid, nearly sub-triangular, forehead nearly smooth with some scattered impressed dots; fastigium verticis wider than scapus, separated by a fine suture from fastigium frontis; ocelli visible but little distinct; without subocular furrow ( Fig. 80B ). Abdominal tergites two and three with stridulatory pegs.

Wings reduced, tegmen not touching in midline, not fully reaching mid of abdomen ( Fig. 80A ). Tegmen with two subcostal veins followed by four undivided veins: Radius, media, cubitus anterior and cubitus posterior; with 3 anal veins.

Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with 4 pairs of large ventral spines (first pair small, on one mid tibia absent) and 1 pair of smaller ventral spurs; hind femur with 5–7 external and 4–8 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.

Coloration. General color uniformly brown; pronotum mostly black except for margin. Face brown, indistinctly marbled; clypeus yellowish. Tegmen brownish.

Male. see Gorochov 2004.

Female. Seventh abdominal sternite unmodified. Subgenital plate separated by a large membranous zone from preceding sternite; otherwise with converging, upcurved lateral margins, setose; tip faintly bilobate ( Fig. 80D ). Ovipositor falcate, strongly curved in subbasal area, afterwards moderately curved; tip subobtuse ( Fig. 80C ).

Measurements (1 female).—body w/o wings: 27; pronotum: 6; tegmen: 10; hind femur: 15; ovipositor: 10 mm.
