Two new species are described in the genus Chrysichthys: C. teugelsi n. sp. from the Cavally River (Ivory Coast) and C. polli n. sp. from the Lower Zaire. C. teugelsi is characterised by a low number of gillrakers and by a short dorsal fin and is closely related to C. maurus and C. auratus. C. polli is related to C. nigrodigitatus and C. bocagii, but is showing a shorter dorsal fin, less gillrakers and a shorter nasal barbell. A new species is described in the genus Phyllonemus, P. bichardi n. sp. from Lake Tanganyika. This new species is characterised by an edentate vomer and by very long barbells, especially the outer mandibulary ones reaching beyond the anal fin base. A new species is described in the genus Auchenoglanis, A. akiri n. sp. from Rivers State, Nigeria. This new species differs from the other species of the genus Auchenoglanis by its larger premaxillary toothplate, by the small dorsal eyes and by the absence of an obvious dotted pattern.
