Abstract: A new species of Moenkhausia is described from tributaries of the rio Paraguay, Brazil. The new species is diagnosed from congeners by characters related to body coloration, the number of lateral line scales, the degree of poring of the lateral line, and number of scales rows above and below the lateral line. Molecular analyses using partial sequences of the mitochondrial gene Cytochrome Oxidase I from specimens of the new species and specimens belonging to morphologically similar species demonstrated that the… Show more

“…The specimens caught were fixed in 4% formaldehyde and subsequently stored in alcohol 70°GL. The specimens were identified according to Britski et al (2007), Graça & Pavanelli (2007) and Benine et al (2009), labeled, weighed and measured. Only adult individuals were analyzed (Gomiero et al, 2008;Montag et al, 2011), considering that the ontogenetic growth can promote significant changes in morphology (Novakowski et al, 2004;Vitule et al, 2008) or feeding habit (Drewe et al, 2004).…”

“…The genus Moenkhausia Eigenmann currently comprises over seventy valid species (Bertaco et al, 2011a(Bertaco et al, , 2011bMariguela et al, 2013) presenting a wide variation in overall shape and pigmentation patterns (Benine et al, 2004), many of which have been described recently (e.g., Benine et al, 2009;Zanata et al, 2009;Marinho, 2010;Marinho & Langeani, 2010;Sousa et al, 2010;Bertaco et al, 2011aBertaco et al, , 2011b. The genus is widely distributed in South America, being present in coastal drainages of the Guyanas, as well as in the río Orinoco, rio Amazonas, rio Tocantins and Araguaia, rio São Francisco, rio Paraná-Paraguay, and Brazilian eastern drainages (Lima et al, 2003).…”

“…This group was defined by the presence of a distinct reticulate color pattern and a "black bar over the terminal portion of caudal peduncle and basal portion of caudal fin that is preceded by a light area on the caudal peduncle". Lima & Toledo-Piza (2001) described M. dyktiota as possibly related to this assemblage, and more recently two species were added to Costa's (1994) group: M. cosmops (Lima et al, 2007), and M. forestii (Benine et al, 2009). Lima & Birindelli (2006) described Moenkhausia petymbuaba, based on specimens collected in Serra do Cachimbo, which is the main geographical barrier between the middle courses of the rio Xingu and the rio Tapajós, where the headwaters of those drainages lie close to each other and are in some cases only separated by a few meters.…”
