( Figs 76, 77 , 702 )

Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 ( Fig. 702 ); genal carina present; mesoscutellum ( Fig. 76 ) with strong reticulation, meshes isodiametric, submedian grooves very weak, running parallel with and close to lateral margins of mesoscutellum; fore coxa with a sharp edge along posterior margin, and hind coxa with a carina along posterior margin; gaster ( Fig. 76 ) elongate and laterally compressed, 4.3× as long as wide and 0.6× as wide as width of mesoscutum.

Female holotype: length of body 2.1mm.

Scape yellowish-brown with dorsal edge dark brown, pedicel and flagellum dark brown. Head with frons including scrobes golden-green, clypeus dark brown; vertex metallic bluish-green. Thoracic dorsum metallic golden-green with blue tinges. Legs with fore and mid coxae dark brown, hind coxa black with metallic tinges; trochanters and femora dark brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 golden-green with posterior margin metallic purplish, remaining tergites metallic purple; gonoplac black.

Antenna with a weak constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons with strong reticulation, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with five setae in two rows close to notauli. Mesoscutellum with strong reticulation, meshes isodiametric; submedian grooves very weak, running parallel with and close to lateral margins of mesoscutellum. Dorsellum with strong sculpture. Propodeum with a strong median carina; callus with two setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation; fore coxa with a sharp edge along posterior margin and hind coxa with a carina along posterior margin. Fore wing with three setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate and laterally compressed; medio-basal Gt 1 without transverse edge or carina dorsally, Gt 1 with weak reticulation and shiny, remaining tergites with strong reticulation.
