Description	The African freshwater fish of Cichlidae are parasitized by five genera of monogeneans belonging to Dactylogyridea. Ectoparasitic Scutogyrus, Onchobdella, and the highly diversified Cichlidogyrus represent three genera located on the gills, while the endoparasitic Enterogyrus and Urogyrus are located in the stomach and the urinary bladder, respectively. The aim of this study was to investigate the phylogenetic relationships between ectoparasitic and endoparasitic dactylogyridaen monogeneans specific to African freshwater Cichlidae and other representatives of Dactylogyridae. All phylogenetic analyses point to the polyphyletic origin of the subfamily Ancyrocephalinae. The phylogenetic position of Scutogyrus longicornis suggests the non-monophyly of Cichlidogyrus. Using LSU rDNA analyses, we found that Enterogyrus and Onchobdella form a clade with Protogyrodactylus, which suggests that endoparasitism in cichlid monogeneans is not an ancestral feature.
