Hippocrepis myocastoris Babero, Cabello et Kinoed, 1979 is redescribed from a naturally infected Myocastor coypus Molina (Rodentia: Myocastoridae) captured in the Negro River (40°07′S; 64°27′W) from Patagonia, Argentina. A total of 31 ovigerous specimens were stained and measured. These specimens of H. myocastoris were similar to paratype in morphology and morphometric characteristics, did not have ventral gland, and mature eggs presented 4 polar filaments on opercular pole. This is the first record of a notocotylid parasitizing aquatic rodents in Argentinean Patagonia.
