Diagnosis (female). Antennal clava solid (Fig. 1028); genal carina absent; mesoscutellum (Fig. 150) with weak reticulation (compared to mesoscutum), submedian grooves very weak, wide apart and diverging towards posterior part, without a median groove; propodeum (Fig. 150) with a strong median carina, with ±parallel sides; hind coxa with a weak carina in apical one-third of posterior margin; gaster (Fig. 150) 2.1× as long as wide, Gt 1 with weak reticulation, remaining tergites with rather strong reticulation.

Female holotype: length of body 1.8mm.

Head with frons metallic bluish-green, antennal scrobes black, clypeus dark brown; vertex metallic bluish-green. Thoracic dorsum metallic bluish-green. Legs with fore and mid coxae dark brown with metallic tinges, hind coxa metallic bluish-green; trochanters dark brown; fore and mid femora dark brown with metallic tinges, hind femur metallic bluish-green, all femora with apex yellowish-brown; tibiae yellowish-white; T1–3 yellowish-white, T4 brown. Petiole black. Gaster with Gt 1,5-7 metallic bluish-green, Gt 2-4 golden-purple; gonoplac black.

Antenna with solid clava. Face below level of toruli with weak reticulation, clypeal area smooth, frons with strong reticulation, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation lateral to ocellar triangle, inside triangle with transverse carinae.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, ±elongate on midlobe; midlobe without median groove, with seven adnotaular setae. Mesoscutellum with weak reticulation; submedian grooves very weak, wide apart and diverging towards posterior part; without a median groove. Dorsellum with strong sculpture. Propodeum with a strong median carina, with ±parallel sides; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation, hind coxa with a weak carina in apical one-third along posterior margin. Fore wing with three setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; Gt 1 with weak reticulation, remaining tergites with rather strong reticulation.
