A note on the synonomy of Bothriocephalus acheilognathi Yamaguti, 1934, B. aegyptiacus Rysavý and Moravec, 1975 and B. kivuensis Baer and Fain, 1958.
Examination of stained and mounted syntype and topotype specimens of Bothriocephalus aegyptiacus Rysavý and Moravec 1974, syntype specimens of B. kivuensis Baer and Fain 1958, and paratype specimens of B. acheilognathi Yamaguti 1934 showed there to be no characters which could be used to differentiate the three species. A scanning electron microscope study of the scolices of paratype specimens of B. aegyptiacus, syntype specimens of B. kivuensis and specimens of B. acheilognathi also revealed no differences. It is therefore suggested that the three species are synonymous, with priority given to the name B. acheilognathi.
