Claudio Borteiro, Francisco Kolenc, Carlos Prigioni


The Neotropical turtle Phrynops williamsi (Testudines, Chelidae) is a scarcely studied species distributed in southern Brazil, north-eastern Argentina, Paraguay and Uruguay. We report herein the finding of a juvenile specimen, it measured 40 mm of carapace length and was collected in February 2013 by Tiago Delpino at San Gregorio de Polanco (32°36'S, 55°50'W), Tacuarembó Department, in a streamlet tributary of the Negro River (MNHN 9487. This new record suggests that P. williamsi is widely distributed over the Negro River basin, at the southern boundaries of the species geographic range.
