Heterospilus orbitus Marsh  sp. n. Figure 92


Body size: 3.5-5.0 mm. Color: head with face and temple dark brown, vertex and frons yellow; scape yellow without lateral brown stripe, flagellum brown with apical 10-12 flagellomeres white; mesosoma dark brown, mesoscutum yellow, lateral lobes often partially brown; metasomal 1, 2 and base of 3 dark brown, apex of tergum 3 and remaining terga dark honey yellow; wing veins brown, stigma brown with yellow apex; legs yellow. Head: vertex and frons strongly circularly costate around ocelli; face granulate; temple in dorsal view narrow, width less than 1/2 eye width; malar space equal to 1/4 eye height; ocell-ocular distance twice diameter of lateral ocellus; 27-32 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum granulate; prescutellar furrow with 3 cross carinae; mesopleuron granulate; precoxal sulcus scrobiculate, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, weakly granular, basal median carina absent, areola not distinctly margined, areolar area rugose, lateral areas rugose posteriorly, granulate or smooth anteriorly. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a interstitial with vein 1M, rarely slightly beyond; 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, basal border with median raised smooth area; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate basally, weakly granulate or smooth apically; terga 4-7 smooth; ovipositor equal to 1/2 length of metasoma.

Holotype female.

The costae of the frons and vertex being circularly around the ocelli and the yellow mesoscutum are distinctive for this species.


The specific name is from the Latin orbitus meaning circular in reference to the circular costae around the ocelli.
