Heterospilus milleri Marsh  sp. n. Figure 78


Body size: 3.5 mm. Color: head dark to light brown; scape yellow with lateral longitudinal brown stripe, flagellum brown with apical 8-10 flagellomeres white; mesosoma dark brown; metasoma dark brown, terga 5-7 yellow; legs yellow, hind tibia at extreme base and hind tarsus brown; wing veins including stigma brown. Head: vertex transversely costate, occasionally weakly so or smooth; frons transversely costate; face smooth; temple in dorsal view broad but not bulging, about equal to eye width; malar space 1/2 eye height; ocell-ocular distance slightly greater than twice diameter of lateral ocellus; 25-32 flagellomeres. Mesosoma: mesoscutal lobes granulate, weakly rugose along notauli; notauli scrobiculate, meeting at scutellum in triangular costate-rugose area; scutellum smooth; prescutellar furrow with 3 cross carinae; mesopleuron smooth; precoxal sulcus smooth, shorter than width of mesopleuron; venter smooth; propodeum with basal median areas smooth and indistinctly margined, basal median carina absent, areola not distinctly 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 shorter than vein 1M. Metasoma: first tergum longitudinally costate or porcate, slightly longer than apical width; second tergum costate, about 3.5 times wider than long; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate at base, smooth at apex; terga 4-7 smooth; ovipositor longer or slightly shorter than metasoma.

Holotype female.

This species is similar to Heterospilus menkei  but is distinguished by its granulate mesoscutal lobes.
