Resumen:
The diet and histomorphology of thedigestive tract of Melanophryniscus klappenbachi were determined by the analysis of adultand juvenile specimens collected in a private field in Bermejo department, Chaco, Argentina.The sampling was carried out monthly from March to June 2015. 29 specimens were collected, measured, sexed, and dissected for the obtainment of the digestive content and histological samples. The results showed a high tendency towards myrmecophagy; more than95% of the recovered prey items were identified as ants. The histomorphology of the gastrointestinal system consisted of the main four layers of tissue observed in vertebrates: mucosa,submucosa, muscular, and serosa. This study constitutes a contribution to the knowledgeof biology and the natural history of anurans of the Bufonidae family, especially the genusMelanophryniscus, which currently receives a great amount of attention regarding its conservation status.
