Abstract

Cnesterodon hypselurus is an endangered species from the Upper Paraná River basin, with distribution restricted to three streams with diminished habitat quality. An updated distribution including new locations in the Tibagi River basin is presented, increasing its area of occurrence and providing a new low-elevation record of 728 m. The recognition of these populations suggests that C. hypselurus might have a larger distribution in the east-central Paraná State region, changing to vulnerable the previously endangered status of the species.
