First description of female.

Body length 14–23 mm. Body with metallic blue-green. Mandible dark brown, with apex reddish-brown. Antennae black. Wings hyaline, smoky brown; veins and stigma dark brown. Hind femora red except for distal part; tarsi black. Head and scutum with sparse setae; prosternum, mesopleuron and mesosternum densely covered with long setae.

Head. Mandible sharp at apex; inner edge blade-like except apex; without inner teeth (Fig. 8 B ). Clypeus beak-like, anterior margin with three teeth (Fig. 8 B ). Terminal segment of labial palpus setose. Frons with sparse, midsized punctures; frontal carina originating from each frontal lobe absent (Fig. 8 B ). Frontal line short, incomplete (Fig. 8 B ). Vertex with sparse, large punctures (Fig. 8 C ). Gena with sparse, midsized punctures. Ratio of EW: ID = 33: 24. Ratio of F 1: (F 2 + F 3) = 24: 19.

Mesosoma. Pronotal collar nearly rectangular, with several transverse rugae and large punctures; median longitudinal groove shallow (Fig. 8 D ); propleurum with dense, fine punctures and one transverse, narrow groove on each side (Fig. 8 E ); prosternum alutaceous, with sparse, midsized punctures. Scutum with sparse, large punctures; notaulus long, extending to posterior margin, crenulate (Fig. 8 D ). Mesopleuron with dense, large punctures and sparse, small punctures (Fig. 8 F ). Mesosternum alutaceous, with sparse, fine punctures and sparse, midsized punctures (Fig. 8 F ). Omaulus not crenulate (Fig. 8 F ). Sternaulus present, crenulate (Fig. 8 F ). Scutellum with sparse, midsized punctures; anterior margin with one transverse, crenulate groove (Fig. 8 D ). Metanotum with dense, fine punctures and sparse, midsized punctures (Figs 8 D, G ). Propodeal enclosure approximately trapezoid, medially with five strong, longitudinal carinae, including one serrated median longitudinal carina, two strong, oblique, longitudinal carinae on either side, and two serrated oblique, longitudinal carinae located further out to sides; numerous nearly parallel transverse rugae connected five carinae and edge carinae on either side, forming distinct, regular reticulation except posterior central part with irregular reticulation (Fig. 8 G ). Posterior surface of propodeum with distinct, irregular reticulation. Upper part of lateral surface of propodeum with irregular reticulation, rest with sparse, fine punctures (Fig. 8 F ). Two propodeal posterior lateral angles evident (Fig. 8 G ).

Wings and legs. Fore wings with two submarginal cells, vein M + Cu diverging before crossvein cu-a. Hind wings with vein M + Cu diverging at crossvein cu-a (Fig. 8 H ). Claws unidentate (Fig. 8 I ).

Metasoma. T 1 - T 3 with sparse, fine punctures; T 4 - T 6 alutaceous. T 2 with one transverse groove near anterior margin. Metasomal apex laterally compressed.

Male. Differs from female as follows: Body length 7–17 mm. Mandible short, black, with one small, blunt inner tooth near apex (Fig. 9 B ). Clypeus approximately trapezoidal, anterior margin truncate, with one blunt tooth medially (Fig. 9 B ). Terminal segment of labial palpus normal. Frons with dense, large punctures, and approximately irregular reticulation (Fig. 9 B ). Ratio of EW: ID = 34: 25. Ratio of F 1: (F 2 + F 3) = 23: 18. Vertex, gena, pronotal collar, prosternum, scutum, mesopleuron, mesosternum with scattered, midsize punctures (Figs 9 B-F ). Hind wings with vein M + Cu diverging before crossvein cu-a (Fig. 9 H ). Metasomal apex not compressed laterally (Fig. 9 A ).

Distribution.

China (Yunnan).
