Specimens presently identified as belonging to Odontesthes perugiae <\/em>species group from rio Paran\u00e1, rio Uruguay and rio Negro in Argentina, Brazil and Uruguay are revised. Two species are recognized: Odontesthes<\/em> perugiae<\/em>, type species of the genus with Odontesthes orientalis <\/em>as a junior synonym, and a new species described herein. Odontesthes<\/em> perugiae<\/em> is redescribed and its distribution restricted to the lower rio Paran\u00e1, lower rio Uruguay and rio Negro basins. The new species is endemic from the upper rio Uruguay above Salto do Yucum\u00e3 (Brazil) or Saltos del Mocon\u00e1 (Argentina) falls. Both species share with the remaining taxa included in the O.<\/em> perugiae<\/em> species-group (O. bicudo<\/em>, O. ledae<\/em>, O. mirinensis<\/em>, and O. piquava<\/em>) the possession of teeth of the outer row on dentary and premaxilla shorter than those in the inner row, being distinguished from them by the number of gill rakers, body measurements and some osteological characters.<\/p>\n
