Adult trematodes Paralecithodendrium chilostomum (Mehlis, 1831) were detected in the roundleaf bat Hipposideros sp. and in the African sharptooth catfish Clarias gariepinus from Tana Lake, Ethiopia. The catfish is an accidental host for P. chilostomum. This is the first record of P. chilostomum from Ethiopia. The description and figures of P. chilostomum from both host species, Hipposideros sp. and Clarias gariepinus are given.
