genus
The definition of the genus Jupiabais based on six putative synapormorphies related to the structures of pelvic girdle and adjacent musculature (Zanata, 1997; Lima & Zanata, 2005). Jupiabawas proposed by Zanata (1997) to include 21 characid species primarily described in the genera Astyanax Baird & Girardor Deuterodon Eigenmann. More recently, Lima & Zanata (2005) described an additional species, Jupiaba poekotero, from rio Negro drainage. Therefore, Jupiabacurrently comprises 22 valid species, widely distributed throughout the rio Amazonas, rio Essequibo, and rio Oiapoque drainages, plus one single species from the rio Paraguay drainage (Lima et al., 2003; Eschmeyer, 2006). However, the study of Jupiabasamples deposited at the Fish Collection of the Laboratoriode Ictiologia Sistematicada Universidade Federal do Tocantins (acronym UNT) revealed the presence of an undescribed Jupiabaspecies from the rio Tocantins drainage; the description of this species is provided below.
