Heterospilus longisulcus Marsh  sp. n. Figure 170


Body size: 2.5 mm. Color: body brown to dark brown; scape yellow without lateral brown stripe; flagellum brown; wing veins including stigma brown; legs yellow. Head: vertex granulate; frons granulate; face granulate; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance 2.0-2.5 times diameter of lateral ocellus; 21-23 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum granulate; prescutellar furrow with 5 cross carinae rarely with distinct median carina and lateral weaker carinae; mesopleuron granulate; precoxal sulcus scrobiculate, as long as mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina absent, areola not margined, areolar area rugose, lateral areas entirely rugose, propodeum with apical lateral corners weakly but distinctly pointed. Wings: fore wing vein r as long as vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, length greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present but weak; third tergum costate basally, smooth apically; terga 4-7 smooth; ovipositor half as long as metasoma.

1 ♀, same data as holotype (ESUW). 1 ♀, Costa Rica: Puntarenas [;] R.F. Golfo Dulce, [;] 3km. SW. Rincon, 10m [;] x-xii.1990, Paul Hanson (ESUW).


The precoxal sulcus which is as long as the mesopleuron, the fore wing vein r which is as long as vein 3RSa and the pointed apical lateral corners of the propodeum are distinctive for this species.


The specific name refers to the precoxal sulcus that is as long as the mesopleuron.
