The occurrence of the species of the genus Brycon (Characiformes: Bryconidae) in Esprito Santo State is herein reviewed. Brycon opalinus, a species formerly known only from the upper rio Paraba do Sul and upper rio Doce basins, is recorded for the first time in the rio Itapemirim, an independent coastal basin in southern Esprito Santo State, Brazil. With the records of B. opalinus, four Brycon species are now known from Esprito Santo State: B. insignis in the rio Itabapoana basin, on the boundary between Rio de Janeiro and Esprito Santo, B. opalinus in the rio Itapemirim basin, B. dulcis in the rio Doce basin, and B. ferox in the rio Barra Seca, rio Itanas and the rio So Mateus basins. Additionally worth highlighting is that several fisherman and local inhabitants report the occurrence Brycon vermelha in the rio Cotax, a tributary of the rio So Mateus in Esprito Santo and Minas Gerais states, although there are no preserved specimens of B. vermelha from river basins other than the rio Mucuri, in Minas Gerais state.
