A List of Records of Freshwater Aspidogastrids (Trematoda) and Their Hosts in North America

Abstract

Published records for the six species of North American freshwater aspidogastrid trematodes from molluscs and vertebrates have been compiled, listing both hosts and localities for state or province. Seventeen new unionid mussel hosts (Bivalvia) are reported for Aspidogaster conchicola along with new state records for Arkansas, Connecticut, Delaware, Maryland, Mississippi, North Carolina, New York, Virginia, and San Luis Potosi (Mexico); 12 new unionid host species for Cotylaspis insignis, with new state records for Arkansas, Delaware, Massachusetts, Mississippi, New Jersey, Rhode Island, and Wisconsin; five new unionid hosts for Cotylogaster occidentalis, with new state records for Connecticut, Delaware, Florida, and Texas; and a new unionid host record for Lophotaspis interiora. No new records are given for Cotylaspis cokeri nor for C. stunkardi from turtles.
