A New Species Of Hyphessobrycon Durbin (characiformes: Characidae) From The Rio Juruena Basin, Central Brazil, With Notes On H. Loweae Costa & Géry

A new species of Hyphessobrycon, H. peugeoti, is described from the middle portions of the rio Juruena drainage, upper rio Tapajós basin, Mato Grosso State, Brazil. It can be distinguished from all congeners, with the exception of H. loweae and H. heliacus, by a filamentous elongation of the dorsal fin and the approximately straight margin of the anal fin in adult males. It can be distinguished from both H. loweae and H. heliacus by an overall red coloration in life (vs. a golden coloration in life in the latter). Additionally, it can be distinguished from H. heliacus by the lack of chevron-like dark markings along the midline (vs. presence of chevron-like dark-markings in H. heliacus), and from H. loweae by the presence of only five horizontal scale rows between the dorsal-fin origin and the lateral line (vs. 6-7 in H. loweae), and the higher number of branched anal-fin rays (21-24, modally 22, vs. 17-21, modally 20, in H. loweae). Additional meristic, morphometric, and distributional data are provided for Hyphessobrycon loweae, including its first record in the rio Araguaia/Tocantins basin. Comments on a putative monophyletic group including H. peugeoti, H. loweae, H. heliacus, H. elachys, and H. moniliger are presented. © 2013 Sociedade Brasileira de Ictiologia.1113344Almirón, A.E., Casciotta, J.R., Bechara, J.A., Ruiz, D.F.J., A new species of Hyphessobrycon (Characiformes, Characidae) from the Esteros del Iberá wetlands, Argentina (2004) Revue Suisse De Zoologie, 111, pp. 673-682Almirón, A.E., Casciotta, J.E., Körber, S., A new Hyphessobrycon (Characiformes, Characidae) from the río Uruguay basin, Argentina (2006) Revue Suisse De Zoologie, 113, pp. 889-896Benine, R.C., Lopes, G.A., A new species of Hemigrammus Gill, 1858 (Characiformes: Characidae) from Río Caura, Venezuela (2007) Zootaxa, pp. 53-59Bertaco, V.A., Carvalho, T.P., A new characid fish, Hyphessobrycon hexastichos (Characiformes: Characidae) from Chapada dos Parecis, Mato Grosso, Brazil (2005) Neotropical Ichthyology, 3, pp. 439-443Bertaco, V.A., Malabarba, L.R., A new species of Hyphessobrycon (Teleostei: Characidae) from the upper rio Tocantins drainage, with bony hooks on fins (2005) Neotropical Ichthyology, 3, pp. 83-88Bertaco, V.A., Malabarba, L.R., Dergam, J., New Hyphessobrycon from the upper rio Pardo drainage in eastern Brazil (Teleostei: Characiformes: Characidae) (2007) Neotropical Ichthyology, 5, pp. 245-250Carvalho, F.R., Langeani, F., Miyazawa, C.S., Troy, W.P., Hyphessobrycon rutiliflavidus n. sp., a new characid fish from the upper rio Paraguai, State of Mato Grosso, Brazil (Characiformes: Characidae) (2008) Zootaxa, pp. 39-49Carvalho, T.P., Bertaco, V.A., Two new species of Hyphessobrycon (Teleostei: Characidae) from upper rio Tapajós basin on Chapada dos Parecis, Central Brazil (2006) Neotropical Ichthyology, 4, pp. 301-308Cockerell, T.D.A., The scales of the South American characinid fishes (1915) Annals of the Carnegie Museum, 9, pp. 92-113. , pls. 23-28Costa, W.J.E.M., Géry, J., Two new species of the genus Hyphessobrycon (Characiformes: Characidae) from the rio Xingú basin, central Brazil (1994) Revue Française D'Aquariologie, 20, pp. 71-76Eigenmann, C.H., The American Characidae [part 2] (1918) Memoirs of the Carnegie Museum, 43, pp. 103-208Fink, S.V., Fink, W.L., Interrelationships of the ostariophysan fishes (Teleostei) (1981) Zoological Journal of the Linnean Society, 72, pp. 297-353Fink, W.L., Weitzman, S.H., The so-called cheirodontin fishes of Central America with description of two new species (Pisces: Characidae) (1974) Smithsonian Contributions to Zoology, 172, pp. 1-46García-Alzate, C.A., Román-Valencia, C., Hyphessobrycon ocasoensis sp.n.
