Heterospilus thereospilus Marsh sp. n. Figure 285

Female.

Body size: 2.5 mm. Color: head with vertex brown, face honey yellow; mesosoma and metasoma dark brown, apical metasomal terga somewhat lighter brown; scape yellow without lateral brown stripe; flagellum brown; wing veins including stigma brown; legs yellow. Head: vertex mostly smooth, occasionally weakly costate behind ocelli; frons smooth; face weakly rugose; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space apparently greater than 1/4 eye height (partially hidden in glue); ocell-ocular distance slightly greater than 2.5 times diameter of lateral ocellus; 19 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting posteriorly in rectangular rugose area; scutellum granulate; prescutellar furrow with 5 cross carinae; mesopleuron granulate; precoxal sulcus weakly scrobiculate, shorter than mesopleuron; venter possibly granulate (obscured by glue); propodeum with basal median areas margined, granulate, basal median carina absent, areola not margined, areolar area areolate-rugose, lateral areas rugose posteriorly, granulate area anteriorly. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a slightly beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, length equal to apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove absent; third tergum costate at extreme base, remainder smooth; terga 4-7 smooth; ovipositor as long as metasomal tergum 1.

Paratypes.

Known only from the holotype.

Comments.

The short ovipositor, absence of the posterior transverse groove on metasomal tergum 3 and the rectangular rugose area on the mesoscutum where the notauli meet are distinctive for this species.

Etymology.

The specific name is an anagram of the generic name Heterospilus .
