. Members of the genus Platyamoeba are among the most common of the free‐living brackish and marine amoebae; yet, to date only twelve species have been documented in the literature and only a limited number of habitats have been sampled globally. During the course of a systematic survey of salt‐marsh amoebae along the east coast of the United States, a new species of Platyamoeba was discovered in sediment samples obtained from a salt marsh at Assateague Island, VA. The species can be distinguished from all other described species within the genus by the presence of a nucleus with a single parietal nucleolus and a floating form with long tapering pseudopods. Its shape varies from flabellate to spatulate as described for species of Platyamoeba and Vannella . The fine structure of the glycocalyx, however, is characteristic of Platyamoeba .
