Description.

Female. Body length 3 mm. Ovipositor sheaths length 1.6 mm. Metallic tinge absent. Body colour predominantly brown. Scape and pedicel yellow. Flagellomeres yellow brown. Head dark brown. Pronotum yellow brown laterally. Legs yellow, coxae browner.

Proximal anellus longer than wide. First funicular segment 2 × as long as wide. Distal antennomeres not forming a distinct clava. Face sculpture engraved, slightly rugose. Face pilosity short and sparse. Supraclypeal area narrow, its delimiting sulci converging near epistomal groove, and its sculpture barely rugose. Lateral ocelli 0.5 × its own diameter far from the eye margin.

Mesosoma. Pronotum long, nearly 1.5-2 × as long as high in lateral view. Mesoscutum transversally striate. Mesoscutellum mostly smooth. Frenal sulcus with shallow crenulation. Mesepimeron sculpture mostly smooth, slightly striate. Metascutellum longer than frenum, with faint longitudinal striae. Propodeum smooth, without median line. Wings with rather dense pilosity, and medially infuscate. Marginal and postmarginal vein widened. Postmarginal vein longer than stigmal vein.

Metasoma. Petiole slightly rugose, 1.7 × as long as high in lateral view. Petiole dorsally without a longitudinal median sulcus. Ovipositor sheaths long, distinctly protruding beyond metasoma apex. Ovipositor sheaths length 2.7 × hind tibia length and 0.5 × body length.
