Length of antenna 1.2 times longer than length of fore femur; mid segments of antennae 7.5–8.3 times as long as wide. Eyes not protruding above vertex in lateral view. Lateral ocelli placed slightly below the middle of eyes. Fastigium of vertex with deep concavities between lateral carinae, 2.4 times wider than width of one eye from above; anterior margin of fastigium weakly excised, median carina of fastigium reaching middle of eye; lateral carinae elevated. Frontal ridge in lateral view deeply excised between eyes. Width of frontal ridge near base of antennae equal to width of 1st antennal segment. Pronotum rugulose, almost reaching apex of hind femora; in dorsal view anterior margin of pronotum straight in the middle; posterior process of pronotum excised; disc of pronotum with 6 tubercules. Median carina of the pronotum in profile arch-like. Prozonal carinae well defined. Hind margin of lateral lobes of the pronotum with a lower sinus only; posterior angles of lateral lobes in dorsal view rounded. Tegmen and hind wings absent. Fore and mid femora with two lappets on upper and lower carinae. Fore femur 3.4 times, mid femur 3.0 times as long as wide. Hind femur stout, 2.2 times as long as wide; upper and lower carina weakly serrate. Upper side of hind tibia with 3–4 outer and 3–5 inner teeth. First tarsal segment of hind legs almost as long as 3rd segment (without claws). Epiproct narrow triangular, with pointed apex. Cerci short, conical. Subgenital plate in lateral view elongated with shallow excision at apex; in ventral view apex of plate weakly excised.

Body rusty black. Head brownish black. Antennae yellowish with black rings. Apical segment of maxillary palps light brown with black marks, other segments black. Dorsal side of pronotun and posterior angles of lateral lobes blackish brown; infrascapular area black. Fore and mid femora black; lappets light brown.
