SUMMARY:

Marine, estuarine and freshwater fish species can host a great diversity of metazoan parasites, especially ectoparasites and endoparasites, thus increasing the importance of ichthyosanitary studies. This study aims to describe new species of Kudoa and Calyptospora in Siluriformes fish and to present the morphological description of
Lernanthropus in commercially important Perciformes fish in the Amazon region, Brazil. The processed and analyzed specimens of Brachyplatystoma filamentosum and Brachyplatystoma vaillantii were obtained in the district of Mosqueiro in Belém, of Macrodon ancylodon were obtained at a free market in Belém and of Nebris microps in Vigia de Nazaré, Pará, through artisanal fishing. Before the specimens were examined, biometrics were carried out. After identifying the parasites, they were morphometrically processed and the samples analyzed using histology, DNA extraction and genetic sequencing. The M. ancylodon and N. microps specimens were identified and their morphological characteristics assessed fresh. Among the main results obtained, it was possible to identify and describe two new parasite species of the genera Kudoa and Calyptospora in the skeletal muscles of Brachyplatystoma filamentosum and in the liver of Brachyplatystoma vaillantii, respectively, and to report the occurrence and morphological description of Lernanthropus sp. in the gills of Macrodon ancylodon.
