Hypostomus nigropunctatus is a loricarid species distributed in the Río Iguazú basin in Brazil. We revised some specimens from the Arroyo Urugua-í basin, Misiones, Argentina, which, based on a morphological comparison, are corroborated to be H. nigropunctatus. These specimens expand the species' known distribution from the Iguazú basin to the Urugua-í basin. Furthermore, this finding is the first record of this species in Argentina.
