( Figs 318, 319 , 1065)

Diagnosis (female). Antenna with a weak constriction between C1 and C2 (Fig. 1065); genal carina present but weak; mesoscutellum ( Fig. 318 ) with median part with strong reticulation, lateral parts with very strong reticulation, meshes elongate, submedian grooves predominantly indistinct, ±straight and slightly diverging towards posterior part; dorsellum without median carina; propodeum ( Fig. 318 ) with a mix of strong carinae and strong reticulation, callus with two setae; gaster ( Fig. 318 ) 2.1× as long as wide, medio-basal Gt1 with a carina shaped like an inverted U (as in Fig. 26 ), tergites with strong reticulation.

Female holotype: length of body 2.1mm.

Scape yellowish-brown with dorsal edge dark brown, pedicel and flagellum dark brown. Head with frons metallic bluish-green, clypeus dark brown in upper half and yellowish-brown in lower half, scrobes black; vertex metallic bluish-green. Mesoscutum black with golden-green tinges, mesoscutellum golden-green, propodeum black. Legs with coxae, trochanters and femora dark brown, tibiae dark yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt1 metallic bluish-green with posterior margin black with metallic tinges, remaining tergites black with metallic tinges; gonoplac black.

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

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, slightly elongate on midlobe; midlobe without median groove, with 12 scattered adnotaular setae. Mesoscutellum with median part with strong reticulation, lateral parts with very strong reticulation, meshes elongate; submedian grooves indistinct in anterior three-quarters and ±distinct in posterior one-quarter, ±straight and slightly diverging towards posterior part; lateral parts with seven scattered setae. Dorsellum with strong sculpture, without median carina. Propodeum with a strong median carina that expands in posterior part; with a mix of strong irregular carinae and reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed below and towards base of wing; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster ovate-elongate; medio-basal Gt1 with a carina shaped like an inverted U; tergites with strong reticulation.
