Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 (Fig. 747); mesoscutum (Fig. 268) with strong reticulation, meshes elongate, and with a weak median groove in posterior one-third; mesoscutellum (Fig. 268) with submedian grooves distinct, curved and diverging towards posterior part, with a ±complete median groove; dorsellum with median carina; propodeum (Fig. 268) with strong irregular carinae medially, callus with four setae; petiole very short, just a narrow band; gaster (Fig. 268) 2.6× as long as wide, medio-basal Gt 1 with short longitudinal carinae laterally, tergites with strong reticulation.
Female holotype: length of body 2.3mm.
Scape dark brown with base yellowish-brown, pedicel and flagellum dark brown. Face below level of toruli golden-green, clypeus dark brown, frons metallic bluish-green, antennal scrobes black; vertex black with metallic green tinges. Mesoscutum dark brown with metallic blue and green tinges, mesoscutellum and propodeum golden-green. Legs with fore and mid coxae dark brown, hind coxa dark brown with metallic tinges; trochanters dark brown; femora dark brown with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 pale brown. Petiole black. Gaster with Gt 1 golden-green, Gt 2-4 golden-purple, Gt 5-6 golden-green, Gt 7 dark brown with golden-green tinges; gonoplac black.
Antenna with a weak constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with a weak genal carina. Vertex with strong reticulation outside ocellar triangle, rugose inside ocellar triangle.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove in posterior one-third, with nine scattered adnotaular setae. Mesoscutellum with strong reticulation on median part and with a weak but ±complete median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, curved and diverging towards posterior part; with four setae scattered over lateral parts. Dorsellum with weak reticulation, with median carina. Propodeum with a few strong irregular carinae on median part, laterally with strong reticulation; callus with four 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; costal setal row unbroken.
