Frank Raynner V Ribeiro Carlos Alberto S Lucena About the authors

The examination of the holotype and 61 of the 64 paratypes of Pimelodus heraldoi, syntypes of P. microstoma and additional specimens from the upper rio Paraná showed that the former species is a junior synonym of the latter. Both species were originally described from the rio Mogi-Guaçu, upper rio Paraná.
