Diagnosis (female). Antennal clava with distinct constriction between C1 and C2 (Fig. 1070); genal carina absent; mesoscutellum ( Fig. 320 ) with submedian grooves parallel, median part with very weak reticulation; dorsellum with median carina; petiole very short, just a narrow band; gaster ( Fig. 320 ) 3.2× as long as wide, medio-basal Gt1 with a transverse carina dorsally; gonoplac yellowish-brown ( Fig. 321 ).

Female holotype: length of body 2.8mm (paratypes 2.8–3.0mm).

Colour (specimen is light-bleached). Scape yellowish-white, pedicel and flagellum brown. Face below level of toruli golden-green with lower part brown, clypeus yellowish-brown, frons metallic bluish-green, antennal scrobes black; vertex dark brown with blue tinges. Thoracic dorsum golden-green, median part of mesoscutellum also with blue tinges. Legs with fore and hind coxae dark brown with metallic tinges, mid coxa pale brown; trochanters yellowish-brown; femora dark brown with apex yellowish-white; tibiae yellowish-white; T1–3 yellowish-white, T4 brown. Petiole dark brown. Gaster with Gt1 metallic bluish-green, remaining tergites dark brown with metallic tinges; gonoplac yellowish-brown.

Antenna with distinct constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.

Mesoscutellum with weak reticulation on median part, lateral parts with strong reticulation, meshes elongate; submedian grooves ±distinct, straight and parallel; with 11 setae scattered over lateral parts. Dorsellum with strong reticulation, with median carina. Propodeum with a wide median carina that expands in posterior part; with strong irregular carinae and strong reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with 5&6 setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt1 with a transverse carina dorsally; tergites with strong reticulation.
