Body size: 2.0 mm. Color: head with vertex brown, face honey yellow, mesosoma and metasoma brown to dark brown; scape yellow without lateral brown stripe, flagellum brown with apical 5-7 flagellomeres white; wing veins including stigma brown; legs yellow. Head: vertex smooth; frons smooth; face smooth; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance greater than 2.5 times diameter of lateral ocellus; 14-16 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular costate area; scutellum weakly granulate; prescutellar furrow with 1 cross carina; mesopleuron granulate; precoxal sulcus weakly scrobiculate, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina present, areola distinctly margined, areolar area rugose, lateral areas rugose posteriorly, small granulate area anteriorly. Wings: fore wing vein r slightly shorter than vein 3RSa, vein 1cu-a slightly beyond vein 1M; hind wing vein SC+R absent, vein M+CU equal in length to vein 1M. Metasoma: first tergum longitudinally costate, length greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum entirely smooth; terga 4-7 smooth; ovipositor as long as metasomal terga 1 and 2 combined.

1 ♀, same data as holotype (ESUW). 2 ♀♀, Costa Rica: Puntarenas [;] R. F. Golfo Dulce, 24km. [;] W. Piedras Blancas, 200m [;] I.1993, P. Hanson (ESUW). 2 ♀♀, COSTA RICA: Puntarenas [;] RF Golfo Dulce el 200m [;] 24km W Piedras Blancas [;] P. Hanson ix.1992 and vi.1993 (TAMU).


The flagellum with an apical white annulus, the smooth metasomal tergum 3 and hind wing vein M+CU being equal in length to vein 1M are distinctive for this species.
