| Summary: | Proteocephalid cestode hyperparasite are reported from numerous proteocephalids occurring in pimelodid fishes in different regions of Brazil. In addition, three specimens of a nematode hyperparasite are reported from the proteocephalid cestode Choanoscolex abscissus from the pimelodid fish Pseudoplatystoma corruscans in Brazil. Previous records of cestode and nematode hyperparasite of cestode are listed, and the possible identities of the Brazilian records are discussed.<br>Cestóides hiperparasitos são descritos de espécies de proteocefalídeos, que ocorrem em peixes pimelodídeos de diferentes regiões do Brasil. Referimos ainda, a ocorrência de nematóide hiperparasito em espécimes de Choanoscolex abscissus, do peixe pimelodídeo, Pseudoplatystoma carruscans. São citadas as referências anteriores de cestóides e nematóides hiperparasitos, e discutida a possível identificação dos mesmos. |
