| Popis | Several recent checklists reported extremely diverse helminth fauna of freshwater fish in Iraq. Nonetheless, from the molecular phylogenetic standpoint, this region is largely unexplored, as almost no DNA sequence data for parasites of endemic fish are available. As the Middle East played an important role in the colonization of Europe and North Africa by cyprinoid fish, we expect close phylogenetic relationships among congeneric helminths from these continents. Our research aimed to investigate the monogenean diversity of cyprinoid fish in Iraq using an integrative approach, combining morphology with genetics. A total of 15 cyprinoid species were examined in 2021 for the presence of ectoparasitic and endoparasitic helminths. The highest species diversity was recorded for Dactylogyrus with 17 species (5 species were recognized as new for science and described), and Gyrodactylus with 12 species (all new for science). In addition, four species of Dogielius (2 new for science), and two species of Paradiplozoon were recorded on endemic cyprinoids. Phylogenetic reconstructions based on the commonly used genetic markers revealed paraphyletic relationships among endemic congeneric helminth taxa (i.e., Dactylogyrus and Gyrodactylus). The phylogenetic proximity of the endemic species to African and European congeners supports the assumption that the historical diversification of freshwater species occurred in the Middle Eastern region. The study was financially supported by Czech Grant Agency, project no. 20-13539S. |
