abstract (from publication):
Cyanocharax obi is described from tributaries of the arroyo Paranay–Guazú, río Paraná basin, Misiones province, Argentina. This new species can be distinguished from its congeneres by the following combination of characters: lateral line interrupted or with alternated series of perforated and non perforated scales, 22–24 branched anal-fin rays, body depth at dorsal-fin origin (34.5–40.8% SL), and distal border of anal fin in matures males nearly straight. Validity of the new species is also well supported by a molecular phylogenetic analysis (COI, 12S, 16S). Cyanocharax obi represents the first record of the genus in the río Paraná basin.
