[[
Jupiaba Zanata
]]
The definition of the genus
Jupiaba
is based on six putative synapormorphies related to the structures of pelvic girdle and adjacent musculature (Zanata, 1997; Lima & Zanata, 2005).
Jupiaba
was proposed by Zanata (1997) to include 21 characid species primarily described in the genera
Astyanax Baird & Girard
or
Deuterodon Eigenmann
. More recently, Lima & Zanata (2005) described an additional species,
Jupiaba poekotero
, from rio Negro drainage. Therefore,
Jupiaba
currently 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
Jupiaba
samples deposited at the Fish Collection of the
Laboratorio
de Ictiologia
Sistematica
da Universidade Federal do Tocantins (acronym UNT) revealed the presence of an undescribed
Jupiaba
species from the rio Tocantins drainage; the description of this species is provided below.
