| Description | Distribution of cyprinid genera over Southern European peninsulas is unequal. Only Squalius represents the genus distributed over all three southern peninsulas. Contrariwise, phylogenetically related Telestes and Rutilus are inhabiting only Balkan and Apennine Peninsulas. While the genus Telestes emerged on basis of morphological and molecular diagnostics from the former genus Leuciscus, genus Rutilus was just recently revised. Several former Rutilus species were moved to two new genera. The first one is Leucon comprising northern Apennine and western Balkan species. The other one is monotypic genus Sarmarutilus including only Italian Sarmarutilus rubilio. The recent diversity of Dactylogyrus parasitizing Telestes and Rutilus in relation to the scenario of their diversification was analyzed. A total of 7 species of former Rutilus and 9 species of Telestes were investigated, and Dactylogyrus parasites were collected. Dactylogyrus species richness from Rutilus hosts endemic for southern peninsulas was lower in comparison to widely distributed Rutilus rutilus which harbours up to 9 Dactylogyrus species. Collected Rutilus species were parasitized by 1 to 5 Dactylogyrus species with the highest prevalence of D. erhadovae and shared three Dactylogyrus species i.e. D. sphyrna, D. caballeroi and D. crucifer with common R. rutilus. Four Dactylogyrus species were collected from Telestes species. D. vistulae which is considered as generalist parasitizing a wide range of cyprinid host species, was the most common Dactylologyrus. Telestes and Rutilus shared the complex of Dactylogyrus species morphologically close to the D. rarissimus which is common parasite of R. rutilus. Phylogenetic reconstruction of Dactylogyrus species parasitizing Rutilus and Telestes revealed that D. rarissimus collected from R. heckelii and R. rutilus forms monophyletic group nested within the clade of morphologically related species parasitizing Telestes and Rutilus. |
