Diagnosis.

Head dark brown, lower face with median part yellowish-brown (female, Fig. 309), or white (male, Fig. 310), pale area reaching slightly outside lateral margin of toruli; dorsellum with two large foveae anteriorly (Fig. 760); fore coxa white, hind femur with apical ½ pale brown, remaining parts of legs yellowish-white (Fig. 308); petiole 1.0 × as long as wide; gaster with anterior ½ white with dark brown lateral margins, posterior ½ dark brown (Figs 311, 312); male antenna with scape expanded, widest in the middle, and 2.7 × as long as wide (Fig. 314), 1st flagellomere 3.1 × as long as wide, narrow at base and expanded in apical ⅓.

Description.

Female. Length of body 2.7 mm. Antenna with scape white, pedicel yellowish-white, flagellomere 1 yellowish-brown, 2-6 pale brown (Fig. 313). Mandibles and palpi white. Head dark brown and shiny, lower face with median part yellowish-brown, pale area reaching slightly outside lateral margin of toruli, parts between pale area and eyes dark brown (Fig. 309). Frons close to eyes with two irregular rows of setae (Fig. 319). Vertex smooth (Fig. 320). Occipital margin with a carina behind ocellar triangle (Fig. 320).

Mesosoma black and shiny (Fig. 308). Each sidelobe of mesoscutum with 12 setae. Scutellum 1.0 × as long as wide; with rather strong reticulation (Fig. 321). Dorsellum anteriorly with two large foveae (Fig. 760). Propodeum smooth (Fig. 760); anteromedially with a triangular cup; propodeal callus with nine setae. Legs (Fig. 308): fore coxa white, hind femur with apical ½ pale brown, remaining parts of legs yellowish-white. Fore wing: costal cell with two irregular rows of setae on ventral surface, and margin with three setae close to marginal vein; with 24 admarginal setae in irregular two rows.

Gaster with anterior ½ white with dark brown lateral margins, posterior ½ dark brown (Fig. 311).
