Diagnosis.

Female body length 6.0-6.8 mm, forewing 5.5-6.0 mm (Fig. 79 ); male body length 4.5-5.5 mm; body with obvious white setae, and the setae on the head and mesosoma longer than those on the metasoma; black, with the following parts yellow: base band of clypeus in female, wholly clypeus in male, scape line in male ventrally; small spot of gena near eye, an anterior interrupted band of pronotum dorsally, tegula, parategula, scutellum on posterior half, dorsal spots of mesopleuron, apical margin of femora, tibiae base and dorsally, tarsi, apical bands of T1-T5 (apical bands of T3-T5 incomplete), T2 laterally with circular and medial spots, apical bands of S2-S5. Body with sparse white setae; in front view, clypeus in female slightly wider than long, and apically with semicircular emargination wider than depth (2 ×) (Fig. 80 ), emargination in male wider than in female; clypeus in female with small and sparse punctures, and interspaces between punctures with smaller punctures, with dense white setae laterally (Fig. 80 ), wholly with dense white setae in male; frons and vertex with coarse and dense punctures, interspaces between punctures reticulate (Figs 80 , 81 ); punctures on gena sparser and smaller than above, interspaces between punctures leathery, occipital carina curved latero-ventrally (Fig. 83 ); A13 sharp apically. Mesosoma with coarse punctures, interspaces between punctures finely punctate; punctures of pronotum and mesoscutum dense; other part of mesosoma with sparse punctures; pronotal carina narrow extremely (Fig. 81 ); metapleuron and lateral surfaces of propodeum with unbroken finely horizontal striae (Fig. 82 ); propodeum with long and dense setae, and without carina between dorsal and posterior surfaces (Fig. 84 ); propodeal concavity deep, propodeal carina present in lower part and less than half of propodeal concavity (Fig. 84 ). Metasoma with sparse and coarse punctures (Fig. 85 ); metasomal segments 1-3 punctures lager than those on metasomal segments 4-6; the second metasomal segment with apical lamellae and there with a row of great punctures at base, interspaces between punctures normal, not carina-formed (Fig. 85 ); S2 weak convex in lateral view, with shallow longitudinal medial furrows at base.

Distribution.
