| Description | Phylogenetic analyses based on the large subunit of rDNA sequences of monogeneans belonging to the Dactylogyridea were generated to investigate relationships between specific monogenean parasite species of Cichlidae and other representatives of Dactylogyridae. Monogenean species were collected from seven cichlid species in the National Park Niokolo Koba (Senegal, Africa). All phylogenetic analyses indicated polyphyletic origin of the subfamily Ancyrocephalinae and suggested that Enterogyrus and Onchobdella are each monophyletic. Scutogyrus was nested within Cichlidogyrus, which suggests the non-monophyly of Cichlidogyrus. Moreover, the present phylogenetic analyses showed the monophyly of group including endoparasitic Enterogyrus and ectoparasitic Onchobdella, Cichlidogyrus and Scutogyrus,Protogyrodactylus, Euryhaliotrema and Ligophorus. Therefore, we suggest that endoparasitism is probably a derived feature for cichlid monogeneans. |
