Diagnosis (female). Antennal clava with distinct constriction between C1 and C2 (Fig. 1088); with genal carina; mesoscutellum ( Fig. 530 ) with strong reticulation throughout and with a weak but complete median groove, submedian grooves with outer margin absent, curved and diverging towards posterior part; dorsellum with median carina; propodeum ( Fig. 530 ) short, with strong reticulation and some irregular carinae, median carina ±triangular, callus with six setae; gaster ( Fig. 530 ) 3.3× as long as wide, medio-basal Gt 1 with a sharp edge shaped like an inverted U (as in Fig. 24 ), tergites with strong reticulation, Gt 7 1.7× as long as width at base.

Female holotype: length of body 2.8mm (paratypes 2.6–2.8mm).

Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head with frons, including scrobes, golden-green, clypeus dark brown; vertex golden-green. Thoracic dorsum golden-green with red tinges. Legs with coxae metallic bluish-green; trochanters yellowish-brown; femora metallic bluish-green with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster black with golden-green and metallic blue tinges; gonoplac black.

Antenna with distinct constriction between C1 and C2. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe rugose close to notauli, with a median groove in posterior half, with 18 scattered setae on rugose parts. Mesoscutellum with median part with rather strong reticulation but shiny and with a ±complete median groove, outer margin of submedian grooves absent, lateral parts with very strong reticulation and with seven scattered setae. Dorsellum with strong sculpture, with median carina. Propodeum with triangular median carina; with strong reticulation and some short irregular carinae; callus with six 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.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a sharp edge shaped like an inverted U; tergites with strong reticulation.
