Diagnosis. Female. Body length: 9.0–10.5 mm; black, following parts yellow ( Fig. 11 ): basal spot on mandible, small lateral spots at apex of clypeus, scape ventrally, interantennal spot on lower frons, a small spot on upper gena, two large connected spots on pronotum anteriorly, anterior part of metanotum, and apical bands on both T1-T3 and S2. Cephalic foveae shallow and similar to the surrounding punctures, the surrounding depression of foveae degenerated, its width much less than the distance between posterior ocelli, interocellar region conically tuberculate in frontal view ( Fig. 12 ); vertex depressed and sloping; clypeus with small and sparse punctures, wider than long, shovel-shaped and shallowly emarginate at apex ( Fig. 12 ); anterior surface of pronotum sloping, with distinct punctures and a pair of contiguous round median foveae, pronotal carina obsolete and interrupted medially ( Fig.13 ); propodeum medially with a transverse plane behind metanotum, shorter than length of metanotum, posterior surface concave with complete median longitudinal carina ( Fig. 14 ); T1 with medial longitudinal groove ( Fig. 16 ), apical border of T2 abruptly depressed ( Figs 15, 16 ); anterior surface of S2 sloping; in lateral view S2 somewhat angled basally ( Fig. 15 ), S2 with smaller and sparser punctures than S3 ( Fig. 17 ). Male is unknown.
