Abstract
Two species of the genus Proteocephalus (Cestoda: Proteocephalidae) were collected in fishes from the Paraná River. Proteocephalus vazzolerae n. sp. from Piaractus mesopotamicus and Proteocephalus chubbi, n. sp. from Gymnotus carapo are new species, and are described and illustrated. Proteocephalus vazzolerae n. sp. is characterized mainly by the number of testes and the development of vitellaria. Proteocephalus chubbi n. sp. can be differentiated from its congeners by a combination of characters which include, number of testes, number of proglottids, strobila length, scolex shape and disposition of vitellaria. This is the first record of proteocephalidean in P. mesopotamicus and G. carapo.
