Description.

Female. Length of body 2.8 mm. Antenna with scape yellowish-white in basal ½ and yellowish-brown in apical ½, pedicel yellowish-brown, flagellomeres 1-3 yellowish-brown ventrally and dark brown dorsally, 4-6 dark brown (Fig. 364). Mandibles and palpi yellowish-white. Head black and shiny, lower face medially yellowish-brown with median part pale brown, reaching slightly outside level of lateral margin of toruli, parts between pale area and eyes black (Fig. 360). Frons close to eyes with two rows of setae (Fig. 370). Vertex smooth (Fig. 371). Occipital margin with a weak carina (Fig. 371).

Mesosoma black and shiny (Fig. 359). Each sidelobe of mesoscutum with 12 setae. Scutellum 1.0 × as long as wide; with weak engraved reticulation and with distinctly elongate meshes (Fig. 372). Dorsellum along anterior margin with a very wide groove that is divided by longitudinal carinae, groove 0.5 × as long as length of dorsellum, surface behind groove with a median carina (Fig. 765). Propodeum with very weak reticulation (Fig. 765); anteromedially with a transverse circular cup that has posterior part strongly raised and is distinctly higher than anterior part; propodeal callus with ten setae. Legs yellowish-brown (Fig. 359). Fore wing: costal cell on ventral surface with two rows of setae in basal ⅔ and one row in apical ⅓, and margin with two setae close to marginal vein; with 15 admarginal setae, in one row.

Gaster in anterior ½ yellowish-brown with dark brown lateral margins, posterior ½ dark brown (Fig. 362).
