Diagnosis.

Female body length 5.5 mm, forewing 4.9 mm (Fig. 72 ); black, with the following parts whitish yellow: scape ventrally, pronotum dorsally at anterior half, tegula, parategula, scutellum at posterior half, posterior oblique plane of metanotum, dorsal spot of mesopleuron, apical margins of femora, tibiae and tarsi, apical bands of T1-T2 (band of T1 extended on lateral side) and apical small spots of S2 laterally. Body with dense and coarse punctures; in front view, clypeus wider than long (1.3 ×), and apically emargination wider than depth (2.9 ×) (Fig. 73 ); clypeus with large and dense punctures on apical half, with minute and dense punctures on basal half, outer margin with white setae; frons with dense setae at the lower half (Fig. 73 ); occipital carina developed and forming obvious angle latero-ventrally (Fig. 75 ). Pronotal carina developed and transparent (Fig. 74 ); metapleuron with horizontal striae dorsally and leathery ventrally (Fig. 75 ); propodeum with short and curved carina between dorsal and posterior surfaces, lateral surfaces with fine striae mixed with sparse punctures; without propodeal carina, and sparsely punctate on upper half, propodeal concavity only present in upper part, and obliterate and with oblique striae in lower half crossing posterior surface (Fig. 76 ). Metasoma leathery, with large and coarse punctures (Fig. 77 ); the second metasomal segment with wide apical lamellae and with a row of great punctures at base, interspaces between punctures short carina-formed (Fig. 77 ); S2 weakly convex in lateral view, with shallow longitudinal medial furrows at base, and slightly longer than half of S2 (Fig. 78 ).
