Eupemphix fuscomaculatus Steindachner, 1864 was described from a single specimen collected at Caiçara, Mato Grosso, Brazil. This species is currently included in the genus Pleurodema, and is known only from the holotype and seven specimens from Río Apa, Paraguay, collected by Alfredo Borelli in 1893?1894. Direct examination of Steindachner?s type and Borelli?s specimens revealed that:(1) they are not conspecific; (2) E. fuscomaculatus is a junior synonym of Physalaemus biligonigerus (Cope, 1862); and (3) the specimens from Río Apa, Paraguay, could not be distinguished by their morphology or ploidy either from Pleurodema bibroni or P. kriegi, and are referred here as Pleurodema bibroni based on ecological considerations. Contrary to a recent proposal, the presence of vomerine teeth is not considered diagnostic to differentiate Pleurodema from Physalaemus, as they are absent in P. bibroni and other six species of Pleurodema.
