ABSTRACT
Here we conduct a qualitative and quantitative analysis of ectoparasites and endoparasites of Astyanax altiparanae (Garutti & Britski, 2000), popularly known as lambari-do-rabo-amarelo collected from the Batalha River, State of São Paulo, Brazil. Of the 67 specimens of A. altiparanae, 52 were parasitized by at least one parasitic metazoan species. The following metazoan parasites were found Monogenea, Digenea and Nematoda. The monogenetic Diaphorocleidus sp. was the predominant species, presenting a higher frequency of dominance, prevalence and mean abundance. However, the monogenean Trinigyrus sp. was the one with the highest mean intensity value. All parasites showed aggregate distribution pattern. The parasitic community of A. altiparanae was characterized by low diversity, low richness and low uniformity. The digenetic Rhipidocotyle santanaensis is recorded for the first time in A. altiparanae, in the same way, this parasite is being registered for the first time in the Batalha River.
