Abstract: This study describes the diet of Melanophryniscus devincenzii based on the analysis of stomach contents of 46 specimens from the Parque Municipal de Sertão, south Brazil. We found 935 items belonging to 33 prey categories (excluding plant material). The most important prey categories were Acari, ants (subfamilies Myrmicinae and Ponerinae) and beetles (mainly Polyphaga). These taxonomic categories showed the highest percentage by volume (Acari: 3.94%, Myrmicinae: 16.32%, Ponerinae: 12.17%, undetermined Polyphaga: 13.83%) and the highest index of relative importance (5810.05; 1871.06; 756.47 and 784.57, respectively). The rarefaction curves indicated that females have richer diets than males. According to dietary composition, M. devincenzii may be considered a specialist species, as expected for an active forager.
