A new gorgoderid trematode of the genus Phyllodistomum (Digenea: Gorgoderidae) from Clarias gariepinus (Actinopterygii: Clariidae) in Lake Tana, Ethiopia

A.E. Zhokhov

Abstract. Phyllodistomum tana sp. nov. is described from the ureters of Clarias gariepinus from Lake Tana, Ethiopia. This species is distinguished from its congeners in Africa in having an oblong body shape, transverse loops of the uterus between the posterior margin of ventral sucker and the vitelline follicles, and the localization exclusively in the ureters of C. gariepinus. The new species differs from P. bavuri and P. vanderwaali in the larger size of body, the position of the testes with respect to the ovary and with each other, the lobed vitelline follicles and the sucker ratio.
