Abstract. The paper presents a study of metacercariae collected from Garra dembecha Stiassny et Getahun, 2007 in Lake Tana, Ethiopia. Metacercariae of five unidentified species are described, namely: Diplostomulum sp. 1, Diplostomulum sp. 2, Diplostomulum sp. 3 (Diplostomidae), Ichthyocotylurus sp. 1, Ichthyocotylurus sp. 2 (Strigeidae) and Posthodiplostomum nanum Dubois, 1937. The most striking feature of the Diplostomulum sp. 2 metacercaria is thickening of muscle fascicles at the base of the pseudosuckers. The most characteristic feature of the Diplostomulum sp. 3 is division of a body into the anterior and posterior parts mismatching the anterior and posterior segments of body. This is the first record of Ichthyocotylurus metacercariae from fish in Africa. Detailed morphological descriptions and illustrations of species are presented.
