Diagnosis (female). Antenna with solid clava (Fig. 851); genal carina present; mesoscutellum (Fig. 560) with strong reticulation on median part but shiny, with a median groove in anterior three-quarters, lateral parts with strong reticulation, meshes elongate, submedian grooves distinct, straight and diverging towards posterior part; dorsellum with median carina; propodeum (Fig. 560) with strong reticulation, callus with three setae; gaster (Fig. 560) 1.8× as long as wide, medio-basal Gt1 with a sharp edge shaped like an inverted U (Fig. 24), tergites with strong reticulation.
Female holotype: length of body 1.4mm (paratypes 1.4–1.8mm).
Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head with frons and vertex metallic bluish-green, antennal scrobes black, clypeus dark brown. Thoracic dorsum metallic bluish-green. Legs with fore and mid coxae dark brown, hind coxa metallic bluish-green; trochanters yellowish-brown; femora dark brown with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt1 metallic bluish-green in anterior half, posterior half and remaining tergites golden-purple; gonoplac black.
Antenna with solid clava. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with 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, with ten scattered adnotaular setae. Mesoscutellum with strong reticulation on median part but shiny, with a median groove in anterior three-quarters, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, straight and diverging towards posterior part; with six setae scattered over lateral parts. Dorsellum with weak sculpture and shiny, with median carina. Propodeum with a strong median carina that expands posteriorly and anteriorly; with strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with 3&4 setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.
Petiole very short, just a narrow band. Gaster ovate-elongate; medio-basal Gt1 with a sharp edge shaped like an inverted U; tergites with strong reticulation.

Male. Unknown.
Hosts. Reared from leaf galls induced by an unidentified triozid (Hemiptera: Triozidae) on Pseudolmedia spurea (Moraceae). It is possible that the Galeopsomyia specimens were inquilines (J.A. Azofeifa, personal communication).
Distribution. Costa Rica.
Material examined.
Holotype ♀ COSTA RICA, Puntarenas, Golfito, Estación Agujas, LS 276750_ 526550, 300m. 9.ix.2001, J. Azofeifa (NHMUK). Paratypes (44♀, CNC, MZLU, MZUCR, NHMUK): 7♀ with same label data as holotype; 37♀ COSTA RICA, Puntarenas, Golfito, Estación Agujas, LS 276750_ 526550, 300m, 20.vi.2001, from leaf galls on Pseudolmedia spurea, J. Azofeifa.
Etymology. Named after collecting area, Osa Peninsula where Estación Agujas is located.
