Mandibles and palpi white. Head black and shiny, vertex with parts lateral to ocellar triangle dark reddish-brown, lower face with median part white laterally and yellowish-brown medially, pale area reaching outside of outer lateral margins of toruli, with a black area the width of 1.5 × the width of scape between pale area and eye margin (Fig. 292). Frons close to eyes with two rows of setae (Fig. 302). Vertex with very weak reticulation inside ocellar triangle, outside ocellar triangle smooth (Fig. 303). Occipital margin with a weak carina (Fig. 303).

Mesosoma black and shiny (Fig. 291). Each sidelobe of mesoscutum with nine setae. Scutellum 1.0 × as long as wide; with engraved weak reticulation (Fig. 304). Dorsellum with a wide groove along anterior margin, medially 0.4 × as long as length of dorsellum (Fig. 759). Propodeum with weak reticulation (Fig. 759); anteromedially with a semicircular cup; propodeal callus with six setae. Legs (Fig. 291): fore and mid legs yellowish-white, hind leg yellowish-brown. Fore wing: submarginal vein with four setae; costal cell with two irregular and sparse rows of setae on ventral surface, and margin with two setae close to marginal vein; with 22 admarginal setae, in one row.
