Heterospilus fischeri Marsh sp. n. Figure 41

Female.

Body size: 2.0-2.5 mm. Color: head with vertex and frons light brown, face and eye orbit honey yellow; scape yellow without lateral brown stripe, flagellum brown; mesosoma brown to dark brown; metasomal tergum 1 dark brown, tergum 2 light brown or yellow medially, brown laterally, terga 3-7 light brown to honey yellow; wing veins including stigma brown; legs yellow. Head: vertex weakly transversely striate, often nearly smooth; frons smooth; face smooth, sometimes with weak striations below antennae; temple in dorsal view narrow, less than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance nearly 2.5 times diameter of lateral ocellus; 20-21 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular or nearly rectangular rugose area; scutellum granulate; prescutellar furrow with 3-5 cross carinae; mesopleuron granulate; precoxal sulcus scrobiculate, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina present, areola not distinctly margined, areolar area rugose, lateral areas rugose posteriorly, granulate anteriorly, apical lateral corners of propodeum produced into small tubercles. 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, apical width equal to length; 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 length of metasomal terga 1-2 combined, rarely equal to 1/2 length of metasoma.

Paratypes.

3 ♀♀, same data as holotype except dates of 8-29.xi.1986, 18. i– 8.ii.1986 and second label [BH] Bosque Humedo [;] mature evergreen dry forest [;] [O] in clearing, fully [;] isolated part of day (ESUW).

Comments.

The tubercles at the apical lateral corners of the propodeum are distinctive for this species.
