Resumo: | Characidium xanthopterum is described from tributaries of the upper rio Paraná and upper rio Tocantins basins, in the Central Brazilian Plateau, Goiás State, Brazil. The new species is diagnosed among congeners by the absence of dark bars on the sides of the body in adult specimens, and by the deep yellow coloration in all fins. Ontogenetic change of color pattern is recorded for the first time for Characidium species. Specimens smaller than 32 mm SL possess dark bars on body. These bars disappear with growth between 32 and 35 mm SL, and are always absent in individuals larger than 35 mm SL.
