Diagnosis. Occipital carina complete; POL about 1.0‒1.3× OOL; inner margin of eyes not emarginate; clypeus apically bilobate, with a conspicuous median tooth; dorsellum not carinate, short but strongly convex; propodeum densely pilose, median carina present, plicae present; hind coxa with smooth area extending over two-thirds of depression, without translucent lobe dorso-laterally; hind femur beneath coarsely and sparsely punctate; fore wing ambar, with apical fifth infuscate, and apical process of stigmal vein short, about 0.5× as long as uncus; in females, ovipositor long, reaching at least to dorsellum, small spiniform projection on posterior margin of the tergite VI slightly lower than spiracle level.

Distribution. Brazil (Acre, Amazonas, Minas Gerais, Pará, Rio de Janeiro, Santa Catarina, São Paulo), Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, St. Thomas, Trinidad, Venezuela.

Comments. This species has records widely distributed throughout South America and Brazil ( Figs 25 , 26 ), which suggests that it occurs at intermediate points where it has not yet been found. However, the record presented here for the state of Acre deserves to be highlighted as the first record of Leucospidae in this still poorly-sampled region of the Brazilian Amazon.

Biology. Previously recorded as a parasitoid of the solitary bees Centris tarsata Smith, 1874 ( Chandler et al. 1985), C. bicornuta Mocsáry, 1899 , C. nitida Smith, 1874 , C. vittata Lepeletier, 1841 ( Cooperband et al. 1999), and C. analis (Fabricius, 1804) ( Cooperband et al. 1999; Gazola & Garófalo 2003).
