Rhinella scitula is a small frog belonging to the R. margaritifera group that is found in southwestern and central Mato Grosso do Sul, Brazil, and in the provinces of Amambay and Concepcion in Paraguay. We extend the distribution of the species across the north and the southeast prior distribution limit, and provide an updated map. The distribution of R. scitula encompasses mainly areas with seasonal forests and mountainous landscape in central-western Brazil and northeastern Paraguay.
