Resumo

Leporinus altipinnis is redescribed based on type specimens and additional material from the Amazonas and Orinoco river basins in Brazil and Venezuela. It is distinguished from congeners by having a unique color pattern composed by five dark transversal bars on the trunk in specimens up to 40 mm SL, which split into eight bars in specimens ranging from 60 to 100 mm SL, then into ten bars in specimens of approximately 140 mm SL, and then into 13 or 14 dark bars in specimens larger than 200 mm SL. Leporinus altipinnis is also the only species of banded Leporinus that shows anteriormost rays of dorsal and caudal fins elongate, giving them falcate aspect. Leporinus altipinnis inhabits preferably black-water rivers, and is distributed in tributaries of the Amazonas river basin, such as the Arapiuns and Negro rivers, and in the Orinoco river basin. Leporinus falcipinnis is recognized as a junior synonym of L. altipinnis. In addition, comments on L. holostictus are provided and the species is considered a junior synonym of L. fasciatus. (AU)
