Conteúdo:	The aim of this study was to investigate for the first time the parasite fauna in the Aequidens tetramerus gills of the lower Jari River, State of Amapá (Brazil). In January 2017, 31 specimens of A. tetramerus were collected and they were necropsied using usual methodologies for parasitology of fish. A total of 1,181 parasites were collect and 100% of hosts were parasitized by Gussevia disparoides, Gussevia alioides, Posthodiplostomum sp., Clinostomum sp., Dolops longicauda and Acarina gen. sp. The dominance was of G. disparoides and there was aggregated dispersion of G. disparoides, Posthodiplostomum sp. and Clinostomum sp., while the dispersion of G. alioides, D. longicauda and Acarina gen. sp was random. There were low species richness of parasites (2.45 ± 0.68), low Brillouin diversity index (0.52 ± 0.22), evenness (0.37 ± 0.15) and high Berger‑Parker dominance (0.70 ± 0.15). The parasites community was characterized by low richness of species with high prevalence and low parasitic abundance. Host length had little influence on the abundance of parasites, but host behavior and availability of infective stages of parasites were the factors structuring the parasite community in A. tetramerus. This was the first study on parasites of A. tetramerus from the Jari River basin.
