摘要：Renifer heterocoelium is a parasite of the oral cavity of Neotropical snakes for which larval stages andthe life cycle are still unknown. During studies of parasites of Rhinella schneideri, tadpoles collected in a lake fromthe municipality of Santa Luzia, Minas Gerais, Brazil, yielded specimens with metacercariae adhered to the externalintestinal wall. After morphological characterization, the metacercariae were identified as R. heterocoelium. This is thefirst record and morphological characterization of metacercariae of R. heterocoelium for Brazil.Key words: Rhinella schneideri, Amphibia, Bufonidae, Renifer heterocoelium, Digenea
