Diagnosis. Female and male. Body length: female 6.3–7.0 mm, male 5.0–6.0 mm; black, following parts yellow ( Figs 47, 48 ), in female yellow areas relatively a little smaller: almost whole clypeus except for a small median spot in female, scape ventrally, ocular sinus, interantennal spot on lower frons, a small spot on upper gena, two large connected spots on pronotum anteriorly, posterior part of scutellum, metanotum, a large dorsal spot of propodeum in male, legs largely, wide apical bands on T1–T2, and narrow apical bands on T3–T5 and S2. Almost whole body covered with large and dense punctures, strongly sculptured in both sexes. Cephalic foveae very small and round, the surrounding depression degenerated, its width almost equal to diameter of posterior ocellus; clypeus with dense and large punctures, with a short translucent margin, wider than long in both sexes ( Figs 49, 50 ); male A13 not reaching the base of A11 ( Fig. 52 ); male genitalia, volsella with setae and slightly truncate apically, penis valve rounded apically ( Fig. 57 ); anterior surface of pronotum almost vertical, medially with few punctures and foveae almost V-shaped, pronotal carina complete ( Fig. 51 ); propodeum medially with a transverse plane behind metanotum, slightly shorter than length of metanotum ( Fig. 55 ); apical border of T2 obtusely bent and with a row of bigger punctures, preapical portion of T2 narrowly impressed ( Figs 53, 56 ); anterior surface of S2 sloping, in lateral view S2 rounded ( Fig. 56 ), S2 with large and dense punctures, ventrally in basal portion without a median longitudinal furrow ( Fig. 54 ).
