The genus Pleurodema Tschudi, 1838 consists of thirteen species distributed along southern South America (Frost 2007). Among these, Pleurodema bibroni inhabits Uruguay and southern Brazil (Achaval and Olmos 2003; Machado and Maltchik 2007). Although the systematics of P. bibroni was largely studied in the last century (Barrio and Rinaldi di Chieri 1970; Barrio 1977), it is one of the least known species amongst the amphibian fauna of Uruguay. In spite of this, this species was very common in the Uruguayan coast in the past (Langone, in press) and one observational record was published in recent times (Maneyro et al. 1995), the last specimens stored in scientific collections were collected in 1982. Based on these data, the species is considered as endangered at the national scale in Uruguay (Maneyro and Langone 2001; Canavero et al. 2004), while it is classified as Near Threatened (NT) at the global level (IUCN et al. 2006). The aim of this work is to report a recent record of P. bibroni in southeastern Uruguay.Centro de Investigaciones del Medioambiente
