Fig. 1

Geographic distribution and variation in external morphology of Distichodus species diversity. Map of Africa divided into ichthyofaunal provinces (originally defined by Roberts [1], modified by Lévêque [2], and redrawn according to new hydrological basin mapping published by FAO [3]): Congo Basin (CB), East Africa (EA), Nilo-Sudan (NS), Lower Guinea (LG), South Africa (SA), and West Africa (WA). Shaded area represents Distichodus extent of occurrence. Inset bar charts indicate number of Distichodus species present in each ichthyofaunal province: endemic (red) and total (blue) (when more than endemics). Inset frame fish photographs illustrate the extent of variation in body shape, size, and coloration in Distichodus species (from top to bottom: D. hypostomatus, D. sexfasciatus, D. lussoso, D. antonii, D. affinis, D. shenga, D. decemmaculatus)
