In front view, clypeus wider than long (1.4 × in female, 1.1 × in male), and apically emargination wider than depth (2.3 × in female, 1.8 ×in male) (Figs 29 , 30 ); clypeus in female with sparse and coarse punctures on basal half, with dense and larger punctures on apical half (Fig. 29 ); clypeus in male with sparse and small punctures, with dense white setae (Fig. 30 ); frons, vertex and gena with coarse and dense punctures, occipital carina curved latero-ventrally (Fig. 32 ); A13 sharp at the apex (Fig. 36 ). Mesosoma with coarse and dense punctures; pronotal carina degenerate (Fig. 31 ); metapleuron and lateral surfaces of propodeum with unbroken finely horizontal striae; propodeum posterior surfaces with wide propodeal concavity, with long and oblique striae laterally, propodeal carina present in lower part, and short about 1/3 as long as the propodeal concavity (Fig. 33 ); hind tarsus in male swollen (Fig. 28 ). Metasoma leathery, with sparse and small punctures (Figs 27 , 28 ); the second metasomal segment with wide apical lamellae and there with a row of great punctures at base, interspaces between punctures short carina-formed (Fig. 34 ); S2 strong convex in lateral view (Fig. 34 ), with deep longitudinal medial furrows at base (Fig. 35 ); volsella with lateral processes in the middle and basal parts (Figs 37 , 38 ), penis valve slightly narrow in the middle part, with depression at the top (Fig. 39 ).
