Notocotylus fosteri sp. nov. (Trematoda, Notocotylidae) is described from the caecum of the rice rat, Oryzomys palustris, from a salt marsh on Waccasassa Bay, Florida, U.S.A. The new species differs from previously described Notocotylus species principally in the extreme prebifurcal position of the genital pore, which overlies the posterior margin of the oral sucker, but also by the number of ventral papillae (10-13/row), and the length of the metraterm relative to the cirrus sac (89%). This is only the second species of this genus found in North American mammals.
