C . obscurum (Leidy, 1887) Type host. “Jew-fish”, Megalops thrissoides Valenciennes (non Bloch & Schneider; missapplied name) (Syn. Megalops atlanticus Valenciennes) (Elopiformes: Megalopidae). Originally reported from a jew-fish; however, Stiles & Hassell (1894) suggested the actual species of fish was Stereolepis sp. (sea bass). The only fish that we could find that has been reported from the coastal waters of the USA where the general designation of “Jewfish” has been applied was the Atlantic goliath grouper, Epinephelus itajara (Lichtenstein) (Perciformes: Serranidae) (see Froese & Pauly 2014). This type host report is likely in error, as species of cyclocoelids are to our knowledge typically found in the air sacs, lungs, and infraorbital and nasal sinuses of birds and not in the stomachs of fishes. Type location. USA, specific type locality unknown; specimen from the Comparative Anatomy Series No. 1035 at the Army Medical Museum. Additional hosts. This species subsequently has been reported from a variety of charadriiform birds including the western sandpiper, Calidris mauri (Cabanis) (Syn. Ereunetes mauri Cabanis) (Charadriiformes: Scolopacidae); willet, Tringa semipalmata (Gmelin) (Syns. Catoptrophorus semipalmatus [Gmelin]); Symphaemia semipalmata (Gmelin) (Charadriiformes: Scolopacidae); common redshank, Tringa totanus (Linnaeus) (Syn. Totanus eurhinus Oberholaer) (Charadriiformes: Scolopacidae); common snipe, Gallinago gallinago (Linnaeus) (Syn. Capella gallinago Linnaeus) (Charadriiformes: Scolopacidae); gray-headed lapwing, Vanellus cinereus (Blyth). (Syn. Microsarcops cinereus [Blyth]) (Charadriiformes: Charadriidae); pintailed snipe, Gallinago stenura (Bonaparte) (Syn. Capella stenura [Bonaparte]) (Charadriiformes: Scolopacidae); little ringed plover, Charadrius dubius Scopoli (Charadriiformes: Charadriidae)— Yamaguti (1971). NHMUK on-line Host-Parasite Database lists 27 avian host species. Additional localities. Reported to be basically cosmopolitan (Asia; Europe; North America)— ...
