Description.

Female. Length of body 2.2 mm. Antenna with scape yellowish-white, pedicel yellowish-brown, flagellomeres 1-2 pale brown, 3-6 dark brown (Fig. 160); flagellum long, e.g. 1st flagellomere 3.0 × as long as wide. Mandibles and palpi white. Head black and shiny, lower face with median part yellowish-brown, pale area reaching to level of outer lateral margins of toruli, with parts between pale area and eyes black (Fig. 156). Frons close to eyes with two rows of setae (Fig. 166). Vertex with very weak reticulation inside ocellar triangle, smooth outside (Fig. 167). Occipital margin rounded (Fig. 167).

Mesosoma black and shiny (Fig. 155). Each sidelobe of mesoscutum with 13 setae. Scutellum 1.0 × as long as wide; with very weak engraved reticulation, posterior margin smooth (Fig. 168). Dorsellum anteriorly with a very narrow groove that is divided by longitudinal carinae (Fig. 742), groove medially 0.1 × as long as length of dorsellum. Propodeum with very weak reticulation (Fig. 742); anteromedially with a transverse semicircular cup; propodeal callus with eight setae. Legs yellowish-white with fore and mid coxae white (Fig. 155). Fore wing: submarginal vein with four setae; costal cell on ventral surface with one row of setae, and margin with five setae close to marginal vein; with 20 admarginal setae, partly in two rows.

Gaster with anterior ½ white with dark brown lateral margins, followed by a wide dark brown transverse band, and with apex yellowish-brown (Fig. 158).
