Helminth parasites of fishes from the arabian gulf 2 . the digenetic trematode genera Hamacreadium linton, 1910 and cainocreadium Nicoll, 1909

Abstract

The status of the related digenetic trematode genera Hamacreadium Linton 1910 and Cainocreadium Nicoll, 1909 is briefly reviewed. Hamacreadium Linton 1910 is described from Lutjanus fulviflamma and L. russelli. Cainocreadium epinepheli (Yamaguti, 1934) Durio and Manter, 1968 is described from Lethrinus nebulosus, Epinephelus tauvina, E. chlorostigma, E. areolatus and E. summana. Hamacreadium ghardagense Ramadan, 1983 is transferred to the genus Cainocreadium and thus a new combination, Caincoreadium ghardagense is suggested.
