SUMMARY:

The present work aimed to expand knowledge about the biodiversity of fish parasites. In chapter 1, a new species of the genus Ceratocolax is described based on specimens collected Tomtate Grunt Haemulon aurolineatum captured on the coast of Angra dos Reis, in the state of Rio de Janeiro, Brazil. Bomolochids are common parasites, found mainly in the branchial cavities, but can also be found in the nostrils, nasal sinuses or orbits of their hosts. The genus Ceratocolax has two valid species. The female of the new species can be distinguished from its congeners by the second endopodal segment of leg 3 with one seta and the lack of stout spinules along outer margins on rami of legs 2-4. In chapter 2, was analyzed the parasitic fauna of Paralonchurus brasiliensis captured on the coast of the state of Rio de Janeiro, Brazil. One hundred specimens of P. brasiliensis were necropsied. The analysis only included parasite species with a prevalence greater than 10%. Sixteen species of parasites were collected. P. brasiliensis is a new host record for 4 of the sixteen species collected. Larval endoparasites represented 79.22% of all parasites collected. The nematode Contracaecum sp. was the most abundant, dominant and prevalent species, representing 52.538% of the metazoan parasites collected.
