Heterospilus nigragonatus Marsh sp. n. Figure 86

Female.

Body size: 3.0-4.0 mm. Color: head yellow or honey yellow, temple just behind eye often brown; scape honey yellow without lateral longitudinal brown stripe, flagellum brown with apical 5-7 flagellomeres white; mesosoma dark brown, yellow along notauli, median mesoscutal lobe often light brown, mesopleuron along precoxal sulcus often light brown; metasomal tergum 1 dark brown, tergum 2 usually dark brown, often lighter, terga 3-7 dark brown basally, yellow apically; wing veins brown, stigma usually brown, often yellow at apex; legs yellow, hind tibia dark brown at base. Head: vertex transversely costate; frons transversely costate; face weakly striate or 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 about twice diameter of lateral ocellus; 28-32 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum granulate; prescutellar furrow usually with 3 cross carinae, rarely with 1 distinct median carina and 2 weaker carinae on each side; mesopleuron granulate; precoxal sulcus weakly scrobiculate or smooth, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina present, areola distinctly margined, areolar area rugose, lateral areas rugose posteriorly, granulate anteriorly. 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, apical width less than length; second tergum longitudinally costate, nearly 4 times as wide as long; anterior transverse groove present, sinuate; posterior transverse groove weakly indicated; third tergum entirely granulate; terga 4-7 granulate; ovipositor as long as metasoma.

Comments.

This species is distinguished by the granulate metasomal terga, the narrow second tergum and the dark brown knee of the hind tibia.

Etymology.

The specific name is from the Latin nigra meaning black and the Greek gonatus meaning knee in reference to the yellow hind tibia which is black at the joint with the femur.
