Ascocotyle longa Ransom, 1921
This parasite was originally described from an Alaskan Fox (Vulpes lagopus) that died in the National Zoo in Washington DC. It has been reported from dogs in Cairo and Alexandria (Azim MA. 1938. On the intestinal helminths of dogs in Egypt. J Egypt Med Assoc 21:?????? ). However, others have felt that this was a misidentification of a species that they described as Phagicola longicollis [see above] (Kuntz RE, Chandler AC. 1956. Studies on Egyptian trematodes with special reference to the Heterophyids of mammals. I. Adult flukes, with descriptions of Phagicolalongicollis n. sp., Cynodiplostomumnamrui n.sp., and a Stephanoprora from cats. J Parasitol. 42:445-459.). Recently, cats were experimentally infected cats with Venezuelan mullet meat containing parasites identified as Phagicola longa (Conroy GA de. 1986. Investigaciones sobre la fagicolosis en lisas (Mugilidae ) de aguas americanas. I. Estudios taxonómicos de Phagicola sp. (Trematoda: Heterophyidae) en mugílidos sudamericanos. Rev Iber Parasitol 46:39-46.).
