Heterospilus riveroni sp. n.

( Figs 48–52 )

Female. Body length: 3 mm.

Colour: head entirely black, palpi yellow, scape brown; mesosoma black; metasoma entirely dark brown to black; wing veins and stigma dark brown; all legs yellow.

Head: vertex, frons and face smooth; malar space greater than ¼ eye height; temple shape broad, width shorter than ½ eye width; ocell-ocular distance 2.5 times greater than diameter of lateral ocellus.

Mesosoma : mesopleuron smooth, precoxal sulcus smooth, shorter than width of mesopleuron ; mesoscutum lobes weakly granulate and hairy just along notauli; notauli smooth meeting before prescutellar furrow in triangular costate area; prescutellar furrow with one cross carina; scutellum smooth; propodeum with basal median areas distinct and margined, basal median areas weakly granulate, basal median carina present, areolar margin distinct, areolar area areolate-rugose, lateral areas entirely rugose, mesosternum smooth. Fore wing: vein r shorter than vein 3 RSa, vein 1cu-a beyond vein 1M, stigma wider than length of vein r. Hind wing: vein SC+R present, length of vein M+CU shorter than vein 1M.

Metasoma: first tergum costate, apical width equal length; second tergum costate, apical width three times length; third tergum costate with smooth apex; terga II+III with anterior transverse groove present and straight; posterior transverse groove absent; terga IV–VII smooth; ovipositor equal to length of metasoma.

Material examined. Holotype (DCBU-34590); female, Brazil, SP, Pontal, Usina Bela Vista, semidecidous mesophilic forest, 14.IV.2010, Malaise traps; I.F. Melo col.
