Heterospilus veintiuno Marsh sp. n. Figure 294

Female.

Body size: 3.5-4.0 mm. Color: head with vertex and frons dark brown, face, temple and eye orbits light brown or honey yellow; scape light brown without lateral brown stripe; flagellum brown; mesosoma brown, pronotum occasionally lighter; wing veins including stigma brown; legs yellow; metasoma dark brown, apical terga lighter brown or honey yellow. Head: vertex smooth; frons weakly striate or smooth; face rugose; temple in dorsal view narrow but slightly bulging behind eye, width less than 1/2 eye width; malar space equal to 1/4 eye height; ocell-ocular distance 1.5 times diameter of lateral ocellus; 27 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting posteriorly in triangular rugose-costate area; scutellum weakly granulate; prescutellar furrow with 3 cross carinae; mesopleuron smooth; precoxal sulcus weakly scrobiculate, shorter than mesopleuron; venter smooth; propodeum with basal median areas margined, weakly granulate, 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 beyond vein 1M; hind wing vein SC+R present, vein M+CU as long as vein 1M. Metasoma: first tergum longitudinally costate, length greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior trans verse groove present; third tergum costate basally, smooth apically; terga 4-7 smooth; ovipositor longer than metasoma.

2 ♀♀, same data as holotype except: Canopy fogging 20 and 29; dates of 23.x.1994, 9.x.1994 (ESUW).

Comments.

The rugose face, short ocell-ocular distance and the long ovipositor are distinctive for this species.

Etymology.

The specific name is an arbitrary combination of letters.
