Pisces, Perciformes, Cichlidae, <i>Laetacara dorsigera</i> (Heckel, 1840): Distribution extension and first record for Uruguay River basin, and state of Rio Grande do Sul, southern Brazil

Abstract

The present study records for the first time the small cichlidae fish Laetacara dorsigera (Heckel, 1840) atUruguay River basin and state of Rio Grande do Sul, southern Brazil, previously known from Amazon, Paraná and ParaguayRiver basins. Although the ichthyofauna of Uruguay River basin is relatively well known, this record suggests that thereare still unexplored environments, such as wetlands, where there may be species not yet reported, and found in otherhydrographic systems.
