Rhopalophora Audinet-Serville, 1834 is currently composed of 25 species with a distribution ranging from North to South America. Only nine of them were described from South America and have been recorded exclusively from this continent. The North and Central American species were revised by GIESBERT & CHEMSAK (1993); the South American species, on the other hand, still remain with their descriptions fragmented in different publications that date from 1824 to 1989.The purposes of this work are to redescribe the genus, to gather information on the South American species, to provide updated and standardized descriptions, illustrations, and an identification key, in order to complement that of GIESBERT & CHEMSAK (1993). The following species are treated: R. collaris (Germar, 1824) (type species), R. pulverulenta Guérin-Méneville, 1844, R. venezuelensis Chevrolat, 1859, R. occipitalis Chevrolat, 1859, R. neivai Mendes, 1940, R. prolixa Monné, 1989, R. dyseidia Martins & Napp, 1989, R. casignata Martins & Napp, 1989, and R. paraensis Martins & Napp, 1989.
