Abstract
Cambeva piraquara, sp. nov., a restricted-range and rare species last collected from over 20 years ago, is described from the Rio Piraquara, upper Rio Iguaçu basin, Rio Paraná (La Plata) system. The new species is distinguished from all congeners by having two conspicuous dark-brown longitudinal stripes on the inner skin layer of body over a plain yellowish background: a conspicuous wide and well-defined dark-brown longitudinal mid-lateral stripe extending from the opercular patch of odontodes to the first third of caudal-fin rays and a dorso-sagittal stripe comprising large and coalescent rounded blotches extending from occipital to the dorsal-fin base. We provide an illustrated osteological description and assess the conservation status of the new species, which faces several environmental impacts in the upper Rio Iguaçu basin.

Cambeva piraquara, sp. nov.
Etymology: The specific epithet “piraquara” is an indigenous word that means “fish hole” from the Tupi language: pira = fish and kuara = hole, cave, cavity, or hiding place (Ferreira 2006). The Piraquara River is also the type locality of the new species, a noun in apposition.
