Diagnosis. POL about 1.6‒1.8× OOL; inner margin of the eyes conspicuously emarginate; clypeus apically bilobate, without a conspicuous median tooth; lower tooth of mandibles separated from the upper edge by a triangular excision; dorsellum subtriangular, with deep and broad crenulate furrow along margin, glabrous; propodeum slightly pilose, median carina present, plicae present; hind coxal depression uniformly punctate, with a conspicuous lobe dorso-laterally; hind femur very broad, 2‒2.1× as long as broad, excluding teeth; fore wing with apical quarter infuscate and apical process of stigmal vein shorter than uncus; in female, tergite I usually with two yellow spots posteriorly; tergite VI without spiniform projection at posterior margin; ovipositor reaching the base of gaster; in male, gaster in lateral view with dorsal margin of tergite VI not oblique relative to tergite V.

Distribution. Argentina, Brazil (Amazonas, Pará, Minas Gerais, São Paulo, Santa Catarina), Bolivia, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Mexico, Panama, Peru, Trinidad, Venezuela.

Comments. Leucospis egaia  was previously recorded from northern, southern and southwestern Brazil ( Figs 25 View Figure , 26 View Figure ). The new records presented here extends its occurrence southwestward in the Brazilian Savannah.

Leucospis coxalis  , from Argentina, is morphologically very similar to L. egaia  . Bouček (1974a) used the ovipositor length as a way to distinguish between these species, but for males he used some overlapping measurements that are not as effective for identification. Here we present two characters to distinguish these species. The fore wing of L. coxalis  has the apical process of the stigmal vein as long as the uncus ( Figs 8D, 8J View Figure ), as opposed to an apical process shorter than the uncus in L. egaia  ( Fig. 16D View Figure ). Specifically for males, L. coxalis  has the dorsal mesepisternum with very broad punctation, interspersed with small punctations, and very strong diagonal rugae ( Fig. 7C, D View Figure ), while L. egaia  has the dorsal mesepisternum with very broad punctation, interspersed with very smooth diagonal striae ( Fig. 7A, B View Figure ).

Biology. Unknown. According to Noyes (2017), L. egaia  parasitises Polybia  , a record attributed to Grissell & Cameron (2002), but the latter authors do not mention either of these names. Since the origin of this observation was not found, it is better to consider the biology as unknown.
