Mouth subterminal, premaxilla much longer than dentary; dentigerous tooth plates in both premaxilla and dentary.

Distribution. Amazon, río Orinoco, río Paraná and rio Paranaíba basins.

Remarks. Sorubim lima is a non-native species from the upper rio Paraná, and its occurrence can be associated with the filling of the Itaipu Reservoir and the consequent inundation of the Sete Quedas Falls.
