Female. Length of body 1.9 mm. Antenna with scape yellowish-white and pedicel yellowish-brown, flagellomere 1 yellowish-brown, 2-6 dark brown (Fig. 433). Mandibles dark brown and palpi yellowish-white. Head black and shiny, lower face black with median part very dark reddish-brown, almost black, not delimited from surrounding parts of frons (Fig. 429). Frons close to eyes with one sparse row of setae, row moving away from eye in upper part (Fig. 435). Vertex smooth (Fig. 436). Occipital margin with a weak carina behind ocellar triangle (Fig. 436).

Mesosoma black and shiny (Fig. 428). Each sidelobe of mesoscutum with eight setae. Scutellum 0.9 × as long as wide; with weak engraved reticulation (Fig. 437). Dorsellum along anterior margin with a very narrow groove (Fig. 769), medially 0.1 × as long as length of dorsellum. Propodeum with very weak reticulation (Fig. 769); anteromedially with a triangular cup with posterior part strongly raised and distinctly higher than anterior part; propodeal callus with seven setae. Legs (Fig. 428): fore and mid coxae white, remaining parts of fore and mid legs and entire hind leg yellowish-brown. Fore wing: costal cell with one complete row of setae on ventral surface, and margin with seven setae close to marginal vein; with 18 admarginal setae, in one row in the middle, in two rows at base and apically.

Gaster in anterior ½ yellowish-brown with wide dark brown lateral margins, posterior ½ dark brown (Fig. 431).

Hosts and biology.

Feeding on last instar larvae of Pseudoplusia includens feeding on Acalypha macrostachya , Cecharismena zoum feeding on Acalypha macrostachya ( Euphorbiaceae ), (both hosts are Noctuidae ). Parasitoid cocoons stuck to dead larva and substrate.

Distribution.

Costa Rica (Guanacaste Province).

Etymology.
