New species of Bryconamericus Eigenmann (Characiformes: Characidae) from the rio Teles Pires, rio Tapajos basin, central Brazil

A new species of Bryconamericus is described from the rio Teles Pires, a tributary of the rio Tapajos. The new taxon can be distinguished from its congeners by having a short anal fin with 11-13 branched rays, two maxillary teeth, four outer premaxillary teeth, and 34-38 perforated lateral-line scales. Other diagnostic characters of the species are the absence of a caudal-peduncle spot and the presence of a pigmented vertical band at the caudal-fin rays base. The phylogenetic position of the new species is inferred based in two available phylogenetic hypotheses, and a discussion on its generic placement is provided.
