Heterospilus sumo Marsh sp. n. Figure 195

Female.

Body size: 4.0 mm. Color: body brown; scape brown, flagellum brown with white apical annulus, apical 10-12 flagellomeres white; wing veins including stigma light brown; legs yellow. Head: vertex granulate with transverse rugae behind ocelli; frons granulate; face granulate-rugose; temple in dorsal view narrow, width less than 1/2 eye width; malar space slightly greater than 1/4 eye height; ocell-ocular distance twice diameter of lateral ocellus; 32 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli strongly scrobiculate, meeting at scutellum in triangular rugose area, rugosity extending anteriorly onto median lobe; scutellum weakly granulate or smooth; prescutellar furrow with 3 cross carinae; mesopleuron granulate; precoxal sulcus smooth, shorter than mesopleuron; venter smooth; propodeum with basal median areas not distinct from rest of propodeum, basal median carina absent, areola not margined, areolar area areolate, lateral areas entirely rugose, propodeum with tubercle just above hind coxa at base of petiole. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R present, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate-rugose, length equal to apical width; second tergum longitudinally costate, costae angled toward median line, base of tergum with median raised semicircular granulate area; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate basally, smooth apically; terga 4-7 granulate or costate at base, smooth at apex; ovipositor about 1/2 length of metasoma.

Paratypes.

Known only from the holotype.

Comments.

This species is similar to Heterospilus villegasi but distinguished by the sculpturing on metasomal tergum 2 and the slightly weaker granulation of the mesoscutum.

Etymology.

Named for the Sumo, an indigenous people of Nicaragua.
