N2 - Dactylogyrus are gill parasites almost specific to cyprinid fish. This highly diversified genus includes many host specific species. Many Dactylogyrus coexist on the same host species. Dactylogyrus evolve by intrahost speciation and the species coexisting in the same host differ in their niche position. Cyprinids originate from Asia and classically are divided into several subfamilies: Cyprininae, Rasborinae, Acheilognathinae, Cultrininae, Gobioninae, Tincinae, Leuciscinae and Alburninae. The cyprinids show the specific pattern of biogeographical distribution. Whilst the members of all subfamilies are widely distributed in Asia, some cyprinid groups are absent in Europe. Only the representatives of Cyprininae in Africa and only the representatives of Leuciscinae in North America are present. Previous study focusing on molecular phylogeny using European cyprinid fish species showed that Cyprininae represent plesiomorphic host group. The aims of this study were (1) to analyze phylogenetic position of Dactylogyrus parasitizing African cyprinid fish, and (2) to estimate the role of Dactylogyrus species for inferring historical biogeographical patterns of cyprinid fish species. We showed that Dactylogyrus from cyprinins are not monophyletic. Surprisingly, Dactylogyrus from common carp and gibel carp originated from Asia and recently distributed across Europe together with Dactylogyrus from Labeo and Barbus (i.e. African cyprinins) form a monophyletic group. Dactylogyrus from other Asian cyprinids clustered together with Dactylogyrus of European Gobioninae and Leuciscinae. We demonstrated the nested position of Dogelius and Dactylogyroides in one of two main Dactylogyrus lineages which suggests the need of taxonomic reevaluation.
