Diagnosis (female). Flagellum short, clava very distinct without distinct constrictions between clavomeres (Fig. 850); genal carina absent; mesoscutellum (Fig. 524) with weak reticulation on median part, lateral parts with strong reticulation, meshes elongate; with a strong and complete median groove, submedian grooves distinct, slightly curved and diverging towards posterior part; dorsellum with median carina; propodeum (Fig. 524) with an elongate cup in medio-anterior part that continues as a narrow carina backwards, with strong reticulation lateral to median carina, callus with seven setae; both sexes: fore coxa with a carina along anterior margin (Fig. 18) and hind coxa with a carina along posterior margin; gaster (Fig. 524) 2.1× as long as wide, medio-basal Gt 1 with a sharp edge shaped like an inverted U (as in Fig. 24), tergites with weak reticulation.
Female holotype: length of body 2.3mm (paratypes 1.7–2.8mm).
Scape yellowish-brown with apico-dorsal part brown, pedicel pale brown, flagellum dark brown. Head with frons, including scrobes, and vertex golden-green, clypeus dark brown. Thoracic dorsum metallic bluish-green, propodeum with medio-anterior half golden. Legs with fore and hind coxae metallic bluish-green, mid coxa black; trochanters yellowish-brown; femora with basal half dark brown and apical half yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 metallic bluish-green, Gt 2-4 black with metallic blue tinges, Gt5-6 golden, Gt 7 black; gonoplac black.
Antenna with solid clava. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove in posterior two-thirds, and with 16 scattered adnotaular setae. Mesoscutellum with weak reticulation on median part, lateral parts with strong reticulation, meshes elongate; with a strong and complete median groove; submedian grooves distinct, slightly curved and diverging towards posterior part; with nine setae scattered over lateral parts. Dorsellum smooth and shiny, with median carina. Propodeum with a narrow strong median carina that expands anteriorly and posteriorly; with strong reticulation; callus with seven setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; fore coxa with a carina along anterior margin and hind coxa with a carina along posterior margin. Fore wing with 5&7 setae on dorsal surface of submarginal vein; speculum open below (apical seta absent); costal setal row unbroken.
Petiole transverse. Gaster elongate; medio-basal Gt 1 with a sharp edge dorsally; tergites with weak reticulation, shiny.

Hosts. Reared from seeds of Myrsine juergensenii and Myrsine sp. (Myrsinaceae). The latter (from Zurquí de Moravia) is probably M. coriacea and the seeds of this species harbor an undescribed, phytophagous species of Megastigmus (Megastigmidae) (P. Hanson, unpublished).
Distribution. Costa Rica.
