(Figs 392, 393, 791, 970)
Diagnosis (female). Antennal clava short with a weak constriction between C1 and C2 and with apex pointed (Fig. 791), flagellum short, flagellum+pedicel 1.2× as long as width of mesoscutum; genal carina present; mesoscutellum (Fig. 392) with median part with weak reticulation and shiny, lateral parts with strong reticulation, meshes elongate; submedian grooves with outer margin absent, slightly curved and diverging slightly towards posterior part; dorsellum with median carina; propodeum (Fig. 392) with longitudinal carinae on either side of median carina, lateral to carinae with strong reticulation, callus with four setae; gaster (Fig. 392) 2.2× as long as wide, medio-basal Gt 1 with short longitudinal carinae laterally, tergites with very strong large-meshed reticulation.
Female holotype: length of body 1.9mm (paratypes 2.2mm).
Scape yellowish-brown with apico-dorsal part brown, pedicel and flagellum brown. Head with frons, including scrobes, golden-green, clypeus dark brown; vertex metallic bluish-green. Mesoscutum and mesoscutellum golden-green, propodeum dark brown with metallic blue tinges. Legs with fore coxa dark brown with metallic blue tinges, mid coxa dark brown, hind coxa metallic bluish-green; trochanters, femora and tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster dark brown, Gt 1,5-7 with metallic blue tinges; gonoplac yellowish-brown.
Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth; 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 with parts close to notauli rugose; midlobe with a complete median groove, with 14 scattered setae on rugose parts. Mesoscutellum with median part with weak reticulation shiny, lateral parts with strong reticulation, meshes elongate; submedian grooves with outer margin absent, slightly curved and diverging slightly towards posterior part; with 11 setae scattered over lateral parts. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a strong median carina that expands gradually towards posterior part; with strong irregular carinae and strong reticulation; callus with four setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with six setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.
Petiole transverse with strong sculpture on dorsal part. Gaster elongate; medio-basal Gt 1 with short longitudinal carinae laterally; tergites with very strong reticulation.
