This species was first described as Pimelodus barbancho; however, this is considered a nomen oblitum.[2] It was then described as Pimelodus pirinampu in 1829. In 1858, the genus Pinirampus was described for this species, in which it is usually classified as the only species.[2] However, P. argentinus has been considered a part of this genus.[3]
