Foram investigadas as faunas parasit芍rias de Leporinus lacustris e Leporinus friderici da plan赤cie de inunda o do Alto rio Paran芍, Brasil, objetivando compar芍-las em composi o e estrutura das comunidades seguindo-se metodologias usuais no estudo dos parasitas.Foram observados alguns padr es e as faunas podem ser consideradas semelhantes em estrutura. A principal diferen a nas faunas parasit芍rias refere-se 角s taxas diferenciais de utiliza o das esp谷cies hospedeiras por algumas esp谷cies parasitas em comum, representadas pela abundancia. Esse indicador diferiu entre as esp谷cies de peixes mostrando que, apesar delas serem hospedeiras apropriadas, sua explora o ocorre de forma distinta. The parasite fauna of Leporinus lacustris and Leporinus friderici from the Upper Paran芍 River floodplain, Brazil, was investigated aiming to make a comparison in terms of composition and structure of the communities. Usual methodologies in the study of parasite fauna were applied. Some patterns were observed, and the faunas can be considered similar in structure. The main difference in the parasite fauna was the use rate of the host by some shared parasite species, represented by abundance. This indicator differed in the fish speciesshowing that, although all are appropriate hosts, their exploitation occurs in different ways.
