Leucospis genalis Bouček, 1974a: 94 –96; figs 111, 112. Holotype ♀: Paraguay: Villarica (MCZ, Cambridge); Bouček 1974b: 430 –432; fig. 1.1 (compared L. leptomera ); Martins & Antonini 1994: 556, 558 (hosts); Martins et al. 1996: 13 –14 (hosts); Grissell & Cameron 2002: 277 (compared L. pinna ); Noyes 2017 (online catalog).

Diagnosis. Occipital carina conspicuous only behind ocellar triangle; POL about 0.9‒1.0× OOL; inner margin of eyes not emarginate; clypeus apically bilobate, with a conspicuous median tooth; mandible with lower tooth long, separated from upper edge by a broad semicircular gap; pronotum without premarginal carina; dorsellum subtriangular, bare, coarsely alveolate, its margin with raised sublamellate carina; propodeum densely pilose, median carina present, plicae present; hind coxal depression with coarse punctation dorsally and a broad impunctate streak extending nearly to base, without translucent lobe dorso-laterally; hind femur unusually slender, more than twice as long as broad excluding teeth; fore wing light brown, apical third infuscate, stigma clavate, apical process of stigmal vein about as long as uncus; tergite I without ovipositor sulcus; gaster posteriorly with golden pubescence; ovipositor reaching base of tergite IV; in female, tergite VI without spiniform projection at posterior margin; in male, tergite II dorsally not only visible, but very heavily sculptured.

Distribution. Brazil (Minas Gerais, São Paulo), Paraguay.

Comments. Leucospis genalis was previously recorded from Paraguay and Brazil (state of São Paulo) ( Figs 25 , 26 ). This is the first record from the state of Minas Gerais, which represents the northern most record of this species.

Biology. Previously recorded as a parasitoid of the solitary bees Diadasina distincta (Holmberg, 1903) ( Martins & Antonini 1994) and Ptilothrix plumata Smith, 1853 ( Martins et al. 1996).
