Face punctulate, with weak ocelli; vertex slightly exposed (Fig. 59). Pronotum nearly semicircular, the widest near the truncate hind margin (Fig. 59). Anterior margin convex and incrassate, slightly concave in the middle, with two upturned tubercles (Fig. 59). Anterior half of pronotum depressed, the surface granular; posterior part punctate and elevated, with two tubercles on disc (Fig. 59). Tegmina reduced to sclerotized blades (Fig. 60) which are far separated on the lateral sides of the mesonotum respectively, with apex slightly surpassing hind margin of mesonotum; wings absent (Fig. 17). Anterior ventral margin of front femur with 2-3 spines and with one small distal spine, hind margin with one large distal spine. Abdominal tergites densely punctate, with punctures denser and larger caudally; lateral margins smooth; anterolateral corners without holes.
