Abstract

The present work extends the distribution of Hypostomus uruguayensis to the upper Rio Paraguay basin. This species which was originally described from the Rio Uruguay in Southern Brazil and cited to Argentina and Bolivia is here reported for the first time within the Brazilian Midwest. Additionally, the new population was compared to the original description and the holotype of H. uruguayensis, providing a foundation for brief comments on a diagnosis of H. uruguayensis.
