[On the validity of Ichthyocotylurus variegatus (Creplin, 1825) and the species affiliation of Tetracotyle ovata (v. Linstow, 1877) (Trematoda: Strigeidae) (author's transl)].
Ichthyocotylurus variegatus (Creplin, 1825) is a species of its own, differing from Ichthyocotylurus platycephalus (Creplin, 1825). The distinct morphological difference between the metacercariae of the two species must be stressed (Tetracotyle percaefluviatilis v. Linstow, 1877 = I. variegatus Tetracotyle ovata v. Linstow, 1877 = "T. variegata" sensu Hughes, 1928 = "T. pileata" sensu Dubois, 1938, 1968 = T. communis Hughes, 1928 = I. platycephalus), as well as the different location of the maritae in the definitive host (I. variegatus in the posterior third of the small intestine, I. platycephalus in the region of the cloaca). A key for the determination, synonymes and diagnoses of the metacercariae of the 4 Ichthyocotylurus species are presented.
