Phylogenetic relationships among cheilodactylid and latrid fishes were estimated from cytochrome oxidase I and cytochrome b mitochondrial DNA sequences. Two South African cheilodactylids, Cheilodactylus fasciatus and Cheilodactylus pixi, were divergent from the remaining members of their genus and family, and the monophyly of these groups was rejected based on parametric bootstrap analysis. As C. fasciatus is the nominal species for the genus and family, widespread taxonomic reassignment is implicated for the remaining 12 and 17 members of these groups, respectively. As these 17 cheilodactylids are not genetically or morpho- logically distinct from the latrids, it is proposed that the Latridae should be expanded to encompass them. The inferred relationships among those Cheilodactylus requiring generic reassignment were largely unresolved, and hence few recommendations can be made regarding their placement. Divergence time estimates indicate that chance oceanic dispersal subsequent to Gondwanan fragmen- tation best explains the Southern Hemisphere radiation of cheilodactylids.
