Description: Male: Body median size, cylindrical ( Figure 1 A B ). Head nearly equal pronotum. Frons extremely oblique in profile. Fastigium sharp apex. Fastigial foveolae distinct, triangle. Frontal costa distinct totally, long, slightly shrunken in fastigium ( Figure1 C ). Eyes oval, vertical diameter 1.7–1.8 times transverse, and 2.6–2.7 subocular furrows. Antennae filiform, short, 24 segments, reached the anterior margin of pronotum. Pronotum cylindrical, nearly straight on anterior margin and with a distinct depressed on median posterior margin. Median carina cut by 3 transverse sulci, indistinct before 3rd transverse sulci; lateral carinae absent. Prosternal process tuberculiform, truncate at apex. Mesosternal and metasternal lobes overlap ( Figure1 D ). Tegmina and wings well depended, nearly reached the end of abdominal. Tympanal organ distinct, semicircular, tympanal lobe indistinct. Length of hind femur 6.0–6.4 times the width, upper basal lobe on outer side extremely longer than lower one; lower genicular lobe angular. Hind tibia with 12 spines on inner side and 11 spines on outer side, external apical spine distinct. Cerci long, strongly incurved, apically rounded ( Figure 1 E ). Subgenital plate long, conical, bluntly rounded at apex ( Figure 1 F ).

Female: Body large than male ( Figure 1 G H ). Ovipositor short, dorsal and ventral valvulae both with black denticulations on disto-lateral apex.
