REGO, Amilcar Arandas  and  GIBSON, David I.. Hyperparasitism by helminths: new records of cestodes and nematodes in proteocephalid cestodes from South American siluriform fishes. Mem. Inst. Oswaldo Cruz [online]. 1989, vol.84, n.3, pp.371-376. ISSN 1678-8060.

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.

Keywords : hyperparasitism; proteocephalid cestode; nematode; pimelodid fishes; Brazil.
