Abstract
Rineloricaria is a genus of armored catfish encompassing 67 valid species that are widely distributed throughout the Neotropical region. A new species of Rineloricaria is described from the Paranaíba River, Upper Paraná River basin, southeastern Brazil. sp. n. is distinguished from its congeners by the combination of the following characters: caudal-fin color pattern with basal dark spot and subterminal dark bar on branched rays interspersed with a hyaline area; five series of lateral plates with two keeled in the mid-dorsal series around the insertion of the first ray of dorsal fin; and unbranched caudal-fin ray extended as long filaments.
