Heterospilus masneri Marsh  sp. n. Figure 259


Body size: 2.5-3.0 mm. Color: body dark brown, apical metasomal terga lighter brown; scape light brown without lateral brown stripe; flagellum brown with apical white annulus, apical 3-5 flagellomeres brown; wing veins including stigma brown; legs yellow to honey yellow. Head: vertex smooth, rarely with weak granulations near ocelli; frons smooth; face weakly granulate or striate; temple in dorsal view narrow, sloping behind eye, width equal to 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance slightly greater than 2.5 times diameter of lateral ocellus; 20-24 flagellomeres. Mesosoma: mesoscutal lobes weakly, rarely partially smooth; notauli smooth posteriorly, meeting posteriorly in triangular costate area; scutellum smooth; prescutellar furrow with 3-5 cross carinae; mesopleuron granulate; precoxal sulcus smooth, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, granulate or rarely smooth, basal median carina absent, areola not margined, areolar area areolate-rugose, lateral areas entirely rugose. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a slightly beyond or interstitial with vein 1M; hind wing vein SC+R present, 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 costate basally, smooth apically; terga 4-7 smooth; ovipositor as long as metasomal terga 1 and 2 combined or half as long as metasoma.

The weakly granulate or smooth mesoscutal lobes and the medium length of the ovipositor are distinctive for this species.
