Phylogram of species of Cichlidogyrus inferred from morphological characters under maximum parsimony and using the molecular tree published by Cruz-Laufer et al. [12] as a constraint (specimen IDs refer to samples from Cruz-Laufer et al. [12]). Species of Cichlidogyrus infecting chromidotilapiines cichlids appear nested inside a species group infecting mostly hemichromine cichlids (highlighted in blue), a host tribe with a shared distribution in Central and West Africa.
