Description
Summary:Jupiaba Zanata, 1997 is a genus with small species within Characidae, identified by a pair of modified bones in the form of spines just anteriorly to pelvic-fin base. The genus is mostly distributed throughout the Amazon drainage, except J. acanthogaster (Eigenmann, 1911), which also occurs in the Paraguay river basin. In this work, we recorded for the first time J. acanthogaster in the Sucuriú River drainage, upper Paraná river basin, Brazil. Its occurrence may be a consequence of the historical hydrological interaction between the Paraná and Paraguay river basins.
