In phylogenetics, a derived trait is a trait that is present in an organism, but was absent in the last common ancestor of the group being considered. This may also refer to structures that are not present in an organism, but were present in its ancestors, i.e. traits that have undergone secondary...

 characters. Species level taxonomy of Pimelodus is still poorly known as well as the phylogenetic relationships within and of the genus. The high number of species currently included in Pimelodus, allied to the wide variability in morphology and color pattern of those taxa, pose difficulties for a complete systematic revision of the genus.

A core group within Pimelodus has been diagnozed that includes P. maculatus, P. blochii, P. coprophagus, P. grosskopfii, P. jivaro, and P. pictus.
