Description.

Female. Length of body 2.0 mm. Antenna with scape and pedicel yellowish-brown, flagellomeres 1-2 dark brown dorsally and yellowish-brown ventrally, 3-6 dark brown (Fig. 330). Mandibles and palpi yellowish-white. Head black and shiny, lower face medially dark reddish-brown, pale area extending slightly outside level of lateral margins of toruli, with parts between pale area and eyes black (Fig. 326). Frons close to eyes with one row of setae (Fig. 336). Vertex smooth (Fig. 337). Occipital margin rounded (Fig. 337).

Mesosoma black and shiny (Fig. 325). Each sidelobe of mesoscutum with eight setae. Scutellum 1.0 × as long as wide; smooth and shiny, laterally with very weak engraved reticulation (Fig. 338). Dorsellum along anterior margin with a narrow groove that is divided by longitudinal carinae (Fig. 761), groove medially 0.3 × as long as length of dorsellum. Propodeum smooth (Fig. 761); anteromedially with a triangular cup; propodeal callus with ten setae. Legs yellowish-brown with tarsomeres 1-2 on all legs dark brown (Fig. 325). Fore wing: costal cell with one complete row of setae on ventral surface, and margin with three setae close to marginal vein; with 10 admarginal setae, in one row.

Gaster dark brown, anterior ½ with a narrow pale brown spot (Fig. 328).

Distribution.

Costa Rica (Guanacaste Province).

Etymology.
