Female holotype: length of body 2.6mm (paratypes 1.7–2.7mm).

Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head with frons metallic bluish-green, scrobes black with metallic tinges and clypeus brown; vertex metallic bluish-green. Mesoscutum, mesoscutellum and propodeum golden-green with blue tinges. Legs with fore and hind coxae metallic bluish-green, mid coxa black with metallic tinges; trochanters, femora, tibiae and tarsi yellowish-brown, hind femur with basal half and T4 on all legs brown. Petiole black. Gaster with Gt 1,6 metallic bluish-green, Gt2-5 metallic bluish-green laterally and golden-purple dorsally, Gt

7 black; gonoplac black.

Antenna with a constriction between all clavomeres. Frons with strong reticulation, clypeus smooth, antennal toruli with weak reticulation; genal carina strong, reaching above level of lower margin of eyes. Vertex with strong and dense reticulation, with a strong sulcus from eye margin to posterior ocelli, sulcus continuing from there to median ocellus.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, strongly elongate on midlobe; midlobe with a strong median groove in posterior two-thirds, with eleven adnotaular setae. Mesoscutellum with rather strong reticulation on lateral parts, with weak reticulation on median part, meshes strongly elongate; submedian grooves strong and diverging towards posterior part; with a ±complete weak median groove; with seven setae scattered over lateral parts. Dorsellum with very weak reticulation and shiny, with median carina. Propodeum with a strong median carina that is strongly expanded in anterior and posterior parts but very narrow in the middle; with strong reticulation in anterior half, with longitudinal carinae in posterior half; callus with seven setae. Fore and hind coxae with strong reticulation, mid coxa with very weak reticulation; fore coxa with a carina along both anterior and posterior parts, hind coxa with a longitudinal carina along posterior margin. Fore wing with 6&8 setae on dorsal surface of submarginal vein; speculum open below and towards base of wing; costal setal row unbroken.

Petiole transverse, 0.5× as long as wide, with strong longitudinal carinae. Gaster ovate-elongate; medio-basal Gt

1 with longitudinal carinae; tergites with weak reticulation.
