Abstract: 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 latt… Show more

“…But evidence of faunistic mixing in shield rivers have accumulated in recent years as well. For the most part, they involve adjacent drainages: Tapajós and Paraguay (Shibatta, Pavanelli, 2005;Lima et al, 2007;Birindelli, Britski, 2009;Tapajós, Xingu (Campos-da-Paz, 1999;Birindelli et al, 2008;Menezes et al, 2009);Tapajós, Madeira (Netto-Ferreira, Vari, 2011;Varella et al, 2012); Xingu, Paraguay (Vari, 1991;da Graça et al, 2008;Aquino, Schaefer, 2010;Netto-Ferreira, Vari, 2011); Xingu, Tocantins (Zawadzki et al, 2008;Ingenito et al, 2013); Tocantins, Paraguay (Lucinda, 2005;); Tocantins, São Francisco (Vari, Harold, 2001;Lima, Caires, 2011;Dagosta et al, 2014;Freitas et al, 2015); Tocantins, Upper Paraná (Britski,1997;Lima, Caires, 2011); Madeira, Paraguay (Kullander, 1982;Reis, Malabarba, 1988;Kullander, 2003;Vari et al, 2005;Vera-Alcaraz et al, 2012;Ota et al, 2014); Madeira and Juruena (Dagosta et al, 2016). In all such examples, the hypothesis that ancestral populations of trans-basin taxa were once widespread in the two basins concerned can be refuted because the current watershed divide between them dates from the Precambrian and vastly predate the radiations of Teleostei in the Upper Cretaceous (c. 100-66 Ma) and predate also the origin of the basins themselves .…”

“…Hyphessobrycon Durbin is one of the most species-rich genera of the Characidae, comprising approximately 130 valid species (Carvalho & Langeani, 2013;García-Alzate et al, 2013a, 2013bIngenito et al, 2013). The genus is distributed from Southern Mexico to the rio de La Plata in Argentina, and most of its diversity occurs east of the Andes.…”

“…Attempts to define subgroups within Hyphessobrycon were based mainly on color patterns (e.g., Géry, 1966Géry, , 1977Weitzman & Palmer, 1997;Ingenito et al, 2013), although the monophyly of such groups has never been tested. Several authors (e.g., Eigenmann, 1917;Weitzman & Fink, 1983;Weitzman & Palmer, 1997) commented about the potential nonmonophyletic nature of the genus, a supposition that has been confirmed in recent phylogenetic analyses (e.g., Javonillo et al, 2010;Mirande, 2009Mirande, , 2010Oliveira et al, 2011;Malabarba et al, 2012).…”

“…This is the case for the most diverse characid genera, such as Hemigrammus (54 species), Hyphessobrycon (130 species) and Moenkhausia (76 species) (Weitzman & Fink, 1983;Lima et al, 2003;Eschmeyer, 2013). According to this classification, which is still being used to classify species (e.g., Carvalho et al, 2010;Marinho, 2010;Sousa et al, 2010;Bertaco et al, 2011aBertaco et al, , 2011bIngenito et al, 2013), the genus Hemigrammus is diagnosed from Hyphessobrycon uniquely by the presence of small scales covering the proximal portion of the caudal-fin lobes (vs. absence), and from Moenkhausia by having an incompletely pored lateral line (vs. completely pored lateral line). Based on this system, part of the specimens of the new species would fit into Hemigrammus, whereas part would be best identified as Moenkhausia.…”

“…The Characidae itself encompasses slightly more than half of the number of species in the order, and includes mostly small-sized species generally referred to as "tetras", many of which just recently described (e.g., Ingenito et al, 2013;Mattox et al, 2013) or still waiting to be discovered.…”
