Evolution of host specificity in monogeneans parasitizing African cichlid fish
It is shown that parental care behavior of cichlids may play an important role linked to host specificity of Cichlidogyrus/Scutogyrus parasites, and the study did not support the specialization on predictable resources or ecological specialization hypotheses.
Monogeneans of West African Cichlid Fish: Evolution and Cophylogenetic Interactions
The mapping of morphological characters of the haptor onto the parasite phylogenetic tree suggests that the attachment organ has evolved from a very simple form to a more complex one, and shed some light on the diversification process of Cichlidogyrus species parasitizing West African cichlids.
Two new species of Cichlidogyrus (Monogenea: Dactylogyridae) parasitizing the gills of African cichlid fishes (Perciformes) from Senegal: morphometric and molecular characterization
Two new species of Cichlidogyrus are described from the gills of three species of African cichlids collected from the Gambia River basin in the Niokolo-Koba National Park, Senegal on the basis of morphological differences in the male copulatory organs (MCOs) and apparent similarities in the SSU rDNA and ITS1 sequence data.
Molecular phylogeny of monogeneans parasitizing African freshwater Cichlidae inferred from LSU rDNA sequences
Using LSU rDNA analyses, it is found that Enterogyrus and Onchobdella form a clade with Protogyrodactylus, which suggests that endoparasitism in cichlid monogeneans is not an ancestral feature and proposes a taxonomical revision of the species recently considered to be Scutogyrus.
Evolution of host specificity in monogeneans of Cichlidogyrus/Scutogyrus group parasitizing African cichlid fish.
The mapping of host specificity onto the parasite phylogenetic tree suggests that intermediate specialist parasitizing congeneric hosts represents the ancestral state of host Specificity for Cichlidogyrus/Scutogyrus group.

The highly variable mitochondrial DNA indicated recent population expansion, but no ongoing parasite speciation, confirming, for the first time in freshwater, reduced parasite host specificity in the deepwater realm, probably an adaptation to low host availability.
Two new species of Cichlidogyrus (Monogenea: Dactylogyridae)parasitizing the gills of African cichlid fishes (Perciformes).
During surveys of helminth parasites of freshwater fishes from the Niokolo-Koba National park, Senegal, two new monogenean species of Cichlidogyrus were found on the gills of three species of African…
Evolution and determinants of host specificity of monogeneans parasitizing African cichlid fish.
The mapping of host specificity onto the parasite phylogenetic tree suggests that intermediate specialist parasitizing congeneric hosts represents the ancestral state for Cichlidogyrus/Scutogyrus group, and shows that phylogeny and brooding behavior of cichlids may play an important role for determining host specificity.

The potential of ectoparasites as a tool to reveal basic evolutionary principles as well as host species interactions is illustrated, with a study of monogenean flatworms from Lake Tanganyika.
