Description. FEMALE. Length 2.0− 2.3 mm.

Scape yellowish-brown, pedicel and flagellum dark brown. Frons, vertex, mesoscutum and scutellum metallic bluish-green. Coxae dark and metallic, femora dark brown, tibiae and tarsi yellowish-brown. Forewing with inner ½ ± infuscate. Gastral tergite 1 metallic bluish-green with posterior ½ metallic dark purple, tergites 2–7 metallic dark purple.

Flagellum with 1 small, discoid anellus, 1 large anellus, 2 funiculars and a 3-segmented clava (Figs 70, 88). Frons and vertex with strong, raised reticulation. Antennal scrobes as narrow grooves, not discernible close to toruli, joining below frontal suture; frontal suture as narrow groove in median 1/5 of frons. Occipital margin with sharp edge. Eyes bare.

Mesoscutum and scutellum convex. Mesoscutum 0.5X as long as wide; with strong, raised reticulation; midlobe with 4 pairs of setae; notauli indistinct. Scutellum 1.1X as long as wide; with strong, raised reticulation; with 1 pair of setae. Propodeum with posterolateral part drawn out into a blunt point; propodeum inside spiracular sulcus with 5–6 setae; propodeal surface reticulate-rugose, medially with some irregular longitudinal and narrow carinae. Forewing with 5 setae on dorsal surface of submarginal vein; costal cell bare; speculum large and open below.

Petiole very short, in dorsal view as a very short but wide stripe. Gaster circular to slightly ovate; gastral tergites strongly reticulate.
