RESUMO:

The present work aimed to study the digeneans of the Cladorchiidae and Cryptogonimidae parasites of freshwater fishes in South America using tools of morphological and molecular analysis. Between 2003 and 2018 fish from different basins in this region were necropsied. After being captured, the fish were analyzed for parasite collection. The digeneans found were studied by light microscopy, SEM and through molecular analysis. Cladorchiids and cryptogonimids (types and vouchers) deposited in helminthological collections were also studied. In the chapter I, Goeldamphistomum was proposed to accommodate Goeldamphistomum amazonum and G. peruanum. Iquistostrema was proposed to accommodate Iquitostrema papillatum. These three new species of Cladorchiidae were described in Siluriformes fishes in the Amazon basin, Peru. In the Chapter II, the first phylogenetic analysis of cladorchiids was performed from 28S rDNA, ITS2 rDNA and cox1 mtDNA sequences. Fifteen species were found in Characiformes, Perciformes and Siluriformes fishes in Brazil and Peru, being three new for the science, Microrchis sp. in Pimelodella cristata, Pronamphistoma sp. from Heros sp. and Pseudocladorchis sp. in Pterodoras granulosus. In the Chapter III, Pseudosellacotyla lutzi parasite of Hoplias malabaricus was sequenced (28S rDNA) and the position in phylogenetic analysis within Crytogonimidae was confirmed corroborating with the last proposed classification. Details of their tegument were observed for the first time through SEM. In Chapter IV, Acanthostomum gnerii (Cryptogonimidae) was studied through 28S rDNA, cox1 mtDNA sequences and SEM. This is the first record of the species in the Marapanim river, Pará, Brazil. Ours results showing that the knowledge about cladorchiids and cryptogonimids is incipient in South America.
