The new genus and species Margaritabruchus cherylae Romero and Johnson is described. It is distinct from other genera of bruchids because the ventral surface of the narrow hind femur is not in a gentle, convex curve. It is usually concave before and after an expansion near the middle that ends in a large, blunt, lateral spine about 0.66 from the base of the femur of both sexes. The hind femur of males has a hook-like spine on the lateral margin slightly beyond the blunt spine that is curved toward the base of the femur. The affinities of the genus are with other Acanthoscelidini and it is probably most closely related to Meibomeus and certainly to the very large New World genus, Acanthoscelides Schilsky. Margaritabruchus cherylae feeds in seeds of Indigofera densiflora M. Martens and Galeotti.
