Abstract
This work aimed to describe , sp. nov., endemic to the Rio Iguaçu basin, Brazil and redescribe using external and internal morphological data through the revision of specimens deposited in fish collections including the type material. In this process, we have also added comments on the possible type locality of C. stawiarski. Cambeva cauim, sp. nov. and C. stawiarski are mainly diagnosed by the anatomy and number of procurrent caudal-fin rays in addition to colouration and several meristic and morphometric characters. Both species are compared with other possibly related species and their synapomorphic characters are discussed. Cambeva cauim, sp. nov. and C. stawiarski along with other eight congeners are endemic to the Rio Iguaçu basin, a high impacted freshwater region which could be considered as a biodiversity hotspot to the genus.
