Apharyngogyliauchen callyodontis Yamaguti, 1942 (Digenea) from a New Host, the Common Parrotfish, Scarus psittacus (Scaridae) with Special Reference to its Morphological Intra-SpecificVariations

As part of an on-going study of the helminth parasites collected from the Red Sea fishes, Apharyngogyliauchen callyodontis Yamaguti, 1942 is reported for the first time parasitizing the middle and lower parts of the intestinal tract of Scarus psittacus (Common parrotfish) (Forsskål), collected from...
