Heterospilus wesmaeli Marsh  sp. n. Figure 123


Body size: 3.5-4.0 mm. Color: head yellow; scape yellow without lateral longitudinal brown stripe, flagellum brown; mesosoma dark brown, light brown or yellow along notauli, propleuron and precoxal sulcus; metasomal tergum 1 dark brown, tergum 2 brown medially and laterally with yellow lines medio-laterally, sometimes yellow laterally, terga 3-4 brown, sometimes yellow laterally, terga 5-7 yellow or honey yellow; wing veins including stigma brown; legs yellow, hind tibia yellow with extreme base (knee) dark brown and apical half light brown, tarsus brown. Head: vertex transversely costate; frons transversely costate; face smooth or weakly granulate; temple in dorsal view narrow, less than 1/2 eye width; malar space equal to eye height; ocell-ocular distance twice diameter of lateral ocellus; 26-28 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in wide rectangular rugose area; scutellum weakly granulate; prescutellar furrow with 3-5 cross carinae; mesopleuron weakly granulate, partially nearly smooth; precoxal sulcus smooth, shorter than mesopleuron; venter weakly granulate; propodeum with basal median areas margined, granulate, basal median carina present, areola not distinctly margined, areolar area 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 equal to or longer than vein 1M. Metasoma: first tergum longitudinally costate-rugose, apical width about 3/4 length; second tergum longitudinally costate; anterior transverse groove present, sinuate; posterior transverse groove absent; third tergum costate at base, smooth at apex; terga 4-7 smooth; ovipositor as long as metasoma.

Holotype female.

This species is distinguished by the nearly smooth face, brown knee on the hind tibia and the wide rugose area where the notauli meet.


Named for C. Wesmael who provided some of the early studies of Braconidae  in the early 1800s, particularly for Belgium.
