Descriptions of two new didymozoids from the barracuda Sphyraena obtusata in Kuwait Bay.

Two new species of didymozoid trematodes, belonging to the subfamily Didymozoinae (Ishii, 1935), genus Allodidymozoon Yamaguti, 1959, are described from the barracuda Sphyraena obtusata caught in Kuwait Bay. Allodidymozoon pharyngi n. sp. from cysts in the pharyngeal muscles is distinguished from its congeners by the posteriorly extended testes, glandular cells surrounding the esophagus, and the distribution of the ovarian and vitelline branches in the dorsal side of the hindbody. Allodidymozoon trilobata n. sp. from cysts in the muscles on the inner surface of the operculum is distinguished by the trilobed hindbody and distally curved testes.
