abstract
The subgenus Clypeobarbus Fowler 1936 is elevated to generic rank and distinguished from African "Barbus" by the derived presence of a midlateral row of greatly enlarged, shield-like scales edged with dark pigment and deepest and widest below the dorsal fin, a dark pigment streak situated posterodorsal to the cleithrum, and the presence of a large occipital fontanel, border laterally by the frontals and parietals and posteriorly by the supraoccipital bone of the neurocranial vault. Seven species are placed within Clypeobarbus, C. pleuropholis (Boulenger 1899), C. congicus (Boulenger 1899), C. pseudognathodon (Boulenger 1915), C. bomokandi (Myers 1924), C. hypsolepis (Daget 1959), C. schoutedeni (Poll and Lambert 1961), and C. bellcrossi (Jubb 1965), and a redescription is provided for C. bomokandi, which is rehabilitated as a valid species. 2008 The Ichthyological Society of Japan.
