Abstract. Hypostomus is one of the most diverse genus of South American freshwater catfishes. In Argentina, Hypostomus commersoni Valenciennes, 1836 is distributed throughout the major river networks of the La Plata River basin and in the Pampa Plain. The recent record of H. commersoni in the Langueyú stream, represents the southernmost occurrence for this species and highlights the role of Samborombón bay as a likely dispersal route. It also supports the role of artificial channels in the translocation of freshwater fauna. In this study, a taxonomic revision of H. commersoni from the Langueyú stream was performed and aspects about ichthyofauna dispersal routes are discussed. The taxonomy of populations in the extreme of the species’ distribution range contributes with information about geographic variation of characters.
