Diagnosis (female). Antennal clava solid (Fig. 762); genal carina present; mesoscutellum (Fig. 332) with weak reticulation on median part and shiny, with a weak median groove, lateral parts with strong reticulation, meshes elongate, submedian grooves slightly curved and diverging towards posterior part; dorsellum with median carina; propodeum (Fig. 332) with strong irregular carinae and reticulation, callus with three setae; gaster (Fig. 332) 2.1× as long as wide, medio-basal Gt1 with short longitudinal carinae laterally, tergites with weak reticulation; weakly metallic species (Figs 332, 333).
Female holotype: length of body 1.4mm (paratypes 1.3–1.7mm).
Scape yellowish-brown with dorsal edge brown, pedicel pale brown, flagellum brown. Head dark brown to black with golden-green and blue tinges, clypeus dark brown. Mesoscutum black with metallic tinges; mesoscutellum and propodeum golden-green. Legs with fore and mid coxae dark brown, hind coxa black with metallic blue tinges; trochanters brown; femora dark brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt1 with attachment point of petiole yellowish-brown, anterior two-thirds golden-green and posterior one-third metallic purple, remaining tergites metallic purple; gonoplac black.
Antenna with solid clava. 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 outside ocellar triangle, with wrinkled sculpture inside ocellar triangle.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without median groove, with ten scattered adnotaular setae. Mesoscutellum with weak reticulation on median part and shiny, with a weak median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves slightly curved and diverging towards posterior part; with six setae scattered over lateral parts. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a strong and narrow median carina; with strong irregular carinae and strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with three setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.
Petiole very short, just a narrow band. Gaster ovate-elongate; medio-basal Gt 1 with short longitudinal carinae laterally; tergites with weak reticulation.
