Heterospilus parkeri Marsh sp. n. Figure 177

Female.

Body size: 3.0 mm. Color: body brown to dark brown; scape yellow with lateral longitudinal brown stripe, flagellum brown with apical 8-10 flagellomeres white, apical one often darker; wing veins including stigma brown; legs yellow, coxae and trochanters whitish-yellow, hind femur light brown on apical 3/4. Head: vertex granulate; frons granulate; face granulate; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space equal to 1/4 eye height; ocell-ocular distance about twice diameter of lateral ocellus; 23-24 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular costate area; scutellum weakly granulate or smooth; prescutellar furrow with 1 cross carina; mesopleuron granulate; precoxal sulcus smooth, shorter than mesopleuron; venter granulate; propodeum with basal median areas distinct but not distinctly margined, granulate, basal median carina absent, areola not margined, areolar area rugose, often with median longitudinal carina, lateral areas rugose posteriorly, granulate anteriorly. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, length equal to apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum weakly costate basally, smooth apically; terga 4-7 smooth; ovipositor as long as metasomal tergum 1.

Paratypes.

1 ♀, same data as holotype with Malaise trap 08, #272 and date of 15.xi.1993 (ESUW). 1 ♀, Costa Rica: Puntarenas [;] ACO, Golfito, PN Corcovado [;] Est. Agujas, Charcos, 600m [;] 17. iv– 16.v.1999, J. Azofeifa [;] L.S. 276350-523500 #52776 (ESUW).

Comments.

The absence of hind wing vein SC+R, the smooth apical metasomal terga, the short ovipositor and the indistinctly margined basal median areas of the propodeum are distinctive for this species.

Etymology.

Named for Frank Parker, in remembrance of our days as graduate students at U. C. Davis and in recognition of the many braconids he collected in Costa Rica.
