Heterospilus villegasi Marsh sp. n. Figure 199

Female.

Body size: 3.0 mm. Color: head light brown to brown; scape brown, flagellum brown with white annulus apically, apical 3-5 flagellomeres brown; mesosoma brown, lighter along notauli and upper portion of mesopleuron; metasomal terga brown to dark brown; wing veins including stigma brown; legs yellow, hind femur darker brown on apical half. Head: vertex granulate with weak transverse rugae behind ocelli; frons granulate; face granulate; 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 about twice diameter of lateral ocellus; 21-14 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in wide nearly rectangular rugose area; scutellum granulate; prescutellar furrow with 3-5 cross carinae; mesopleuron granulate; precoxal sulcus smooth, shorter than mesopleuron; venter granulate; propodeum with basal median areas small but not distinctly margined, granulate, basal median carina absent, areola not distinct, areolar area areolate-rugose, lateral areas entirely rugose. 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, length equal to or slightly greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate at base, smooth apically; terga 4-7 smooth; ovipositor equal to half length of metasoma.

Comments.

This species is similar to Heterospilus sumo but differs in the smaller size, sculpturing on metasomal tergum 2 and the coarser granulate mesoscutum.
