Document Type



Two known free-living marine nematodes, Monoposthioides mayri Wieser and Hopper, 1967 and Monoposthia hexalata Chitwood. 1936 are redescribed from sediments in St. Andrew Bay and Lake Powell, Bay County, Florida, U.S.A. One new species of free-living marine nematode, Monoposthia baxteri n. sp., is described from nonvegetated sediments in St. Andrew Bay, Bay County, Florida. M. baxteri n. sp. differs from the other members of the genus in the shape of the gubernaculum which is more similar to that of the species of Monoposthioides than that of Monoposthia.
