Heterospilus once Marsh  sp. n. Figure 265


Body size: 2.5 mm. Color: body dark brown, weakly sclerotized areas at base of metasomal terga 3-5 often white; scape yellow without lateral brown stripe; flagellum brown; wing veins including stigma brown; legs yellow. Head: vertex smooth; frons smooth; face smooth; temple in dorsal view 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; 20 flagellomeres. Mesosoma: mesoscutal lobes smooth; notauli smooth, meeting posteriorly in triangular rugose area; scutellum smooth; prescutellar furrow with 1 cross carina; mesopleuron smooth; precoxal sulcus smooth, shorter than mesopleuron; venter smooth; propodeum with basal median areas margined, smooth, basal median carina present, areola distinctly margined, areolar area smooth, lateral areas rugose apically, smooth basally. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a interstitial with vein 1M; hind wing vein SC+R present, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate-granulate, length nearly twice apical width, median raised area distinctly margined; second tergum longitudinally costate-granulate, apical border raised and smooth, length about 4 times width; anterior transverse groove present, straight; posterior transverse groove weak or absent; third tergum smooth with basal weakly sclerotized area which is often light er colored; terga 4-5 smooth with basal weakly sclerotized area which is often lighter colored; terga 6-7 smooth; ovipositor about 3/4 length of metasoma.

Holotype female.

The weakly sclerotized basal areas of metasomal terga 3-5 are distinctive for this species. It is similar to Heterospilus hansonorum  but is distinguished by the brown flagellum.
