Female. Body (gures 5, 33) length 1.5 mm. H ead and thorax dark green, gaster brown; antennae yellow; hind coxae concolorous with thorax, fore and mid legs brown excepting tibia yellow.

Head (gures 1–3) in front view subtriangle; clypeus small and lower margin emarginate, gena strongly converging to mouth; scrobe very deep, cavity-like (gure 34); scape completely encased in scrobe, vertex slightly convex and lateral area outside of scrobe in upper face with conspicuous projection (gures 2, 5, 35). Antennal (gures 36, 37) insertion below ventral line of eyes; scape not reaching the median ocellus; pedicellus about 1.3 times as long as broad, much longer than rst funicular segment; each funicular segment broader than long; clava as long as the last three funicular segments together; agellum plus pedicellus shorter than the head width. Relative measurements: head width 34, height 26, length 20, eye space 21, eye height 11, malar space 14, POL 5 OOL as 11 5 4.

Thorax convex (gures 5, 39), with weak reticulations. Pronotum narrower than mesoscutum, collar not margined. Notauli shallow and complete. Frenum with large and conspicuous areolations (gurs 39, 40). Propodeum with short median carina, nucha distinct (gure 38). Fore wing about 2.2 times as long as broad; basal cell bare and lower margin open; basal vein without hairs. Fore leg (gures 41, 42) short, tibia with one spur which is shorter than basitarsus; basitarsus with setae in serrate series and literally with three clavate pegs (gure 51). Gaster sessile, ovate, rst gastral tergite half length of gaster (gure 33). Relative measurements: pronotum length 4, mesoscutum length 15, scutellum 17 long, 24 wide, length of propodeum 5, marginal vein 13, postmarginal 2.5, stigmal vein 3 (gure 4); gaster width 33, length 40.

Male. Body smaller than female; others very similar to female except antennae: funicular segments yellow and rst two or three subquadrate, last one slightly broader than long (gure 38), clava brown, distinctly shorter than last three funicular segments together; head in dorsal view with weak reticulation.
