Resumo: A new species of Cyphocharax, Curimatidae, apparently endemic to the blackwater upper rio Negro of the Amazon basin in northern Brazil, is described. The new species is readily distinguished from its congeners by the presence of a distinctly longitudinally elongate, posteriorly vertically expanding patch of dark pigmentation along the midlateral surface of the caudal peduncle, with the patch extending from the base of the middle caudal-fin rays anteriorly past the vertical through the posterior terminus of the adipose fin. The new species additionally differs from all congeners in details of body and fin pigmentation and meristic and morphometric ratios. Evidence for the assignment of the species to Cyphocharax and the occurrence of other species of the Curimatidae apparently endemic to the upper rio Negro catchment is discussed.

A espécie nova é prontamente distinguida de suas congêneres pela presença de uma mancha escura distintamente alongada longitudinalmente e posteriormente expandida na vertical ao longo da superfície lateral do pedúnculo caudal, sendo estendida da base dos raios medianos da nadadeira caudal até a linha vertical do término da nadadeira adiposa. Adicionalmente, a espécie nova difere de todas as congêneres nos detalhes do corpo, pigmentação das nadadeiras e nas proporções merísticas e morfométricas. As evidências para alocação da espécie no gênero Cyphocharax e a ocorrência de outras espécies de Curimatidae aparentemente endêmicas do alto rio Negro são discutidas.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Instituto de Biociências Laboratório de Biologia e Genética de PeixesSmithsonian Institution National Museum of Natural History Department of Vertebrate ZoologyUniversidade Estadual Paulista Instituto de Biociências Laboratório de Biologia e Genética de PeixesSociedade Brasileira de IctiologiaUniversidade Estadual Paulista (Unesp)Smithsonian Institution National Museum of Natural History Department of Vertebrate ZoologyMelo, Bruno F.Vari, Richard P.2015-02-02T12:39:29Z2015-02-02T12:39:29Z2014-04-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article327-332application/pdfhttp://dx.doi.org/10.1590/1982-0224-20130153Neotropical Ichthyology.
