Two cestode species, Fimbriaria fasciolaris (Pallas, 1781) Frölich, 1802 Cloacotaenia megalops (Nitzsch in Creplin, 1829) Wolffhügel,1938 collected from Anas bahamensis Linné, 1758 and Amazonetta brasiliensis (Gmelin, 1758) in lagoons of the Maricá District, State of Rio de Janeiro, Brazil, are described. This is the first record of F. fasciolaris parasitizing A. bahamensis. The prevalence, intensity of infection, and mean intensity of infection for both species are given. Overdispersion distribution is reported for F. fasciolaris with 535 specimens collected in a single A. bahamensis. A key for the genera in the Fimbriariinae is presented. Anatomical features of F. fasciolaris and C. megalops are discussed.
