( Figs 396, 397 , 1072)

Diagnosis (female). Antennal clava solid (Fig. 1072); genal carina present; mesoscutellum ( Fig. 396 ) with very weak reticulation on median part and with a weak ±complete median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, almost straight and diverging towards posterior part; dorsellum with median carina; propodeum ( Fig. 396 ) with strong reticulation, callus with three setae; petiole very short, just a narrow band; gaster ( Fig. 396 ) 2.9× as long as wide, medio-basal Gt1 with longitudinal carinae laterally, gastral tergites with strong reticulation.

Female holotype: length of body 1.8mm.

Scape yellowish-brown, pedicel brown, and flagellum dark brown. Head golden-green, scrobes and parts below level of toruli duller in colour and clypeus dark brown. Mesosoma dark brown with metallic tinges. Coxae, trochanters and femora dark brown, tibiae yellowish-brown; fore tarsus pale brown, mid and hind tarsi with T1–3 yellowish-brown, T4 pale brown. Petiole dark brown. Gaster dark brown, Gt1 with metallic tinges; gonoplac black.

Antennal clava solid. Face below level of toruli with weak reticulation, clypeus smooth, frons with strong reticulation, scrobes with weak reticulation; with a weak genal carina reaching about half-way up to level of lower margin of eyes. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; occipital margin rounded.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with eight scattered adnotaular setae. Mesoscutellum with very weak reticulation on median part and with a weak ±complete median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, almost straight and diverging towards posterior part; with six setae scattered over lateral parts. Dorsellum with weak sculpture, shiny, with median carina. Propodeum with a strong and wide median carina, surface predominantly with strong reticulation; callus with three setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with longitudinal carinae laterally; tergites with rather strong reticulation.
