Abstract A new species of Eigenmannia is described from the upper rio Paraná basin based on morphological and molecular data. It is distinguished for all congeners by a unique combination of morphometrics, meristics, osteological characters, a significant COI genetic divergence that ranges from 4.9 to 15.2%, and its karyotype. An osteological description for the new species is provided, the geographic distribution of Eigenmannia species in the upper rio Paraná basin is commented on, and the use of karyotype information in taxonomic studies is discussed. |
