Female. Length of body 2.9 mm. Antenna with scape yellowish-white, pedicel yellowish-brown, flagellomere 1 pale brown, 2-6 dark brown (Fig. 649). Mandibles and palpi yellowish-white. Head black and shiny, lower face medially yellowish-brown, pale area reaching to level of outer margin of toruli and up between toruli (Fig. 645). Frons close to eyes with one row of setae in lower ½, with two irregular rows in upper ½ (Fig. 656). Vertex smooth (Fig. 657). Occipital margin with a carina behind ocellar triangle (Fig. 657).

Mesosoma black and shiny (Fig. 644). Each sidelobe of mesoscutum with 15 setae. Scutellum 0.9 × as long as wide; with rather strong engraved reticulation (Fig. 658). Dorsellum along anterior margin with a wide groove (Fig. 797), medially 0.4 × as long as length of dorsellum.
