| Popis | Parasitic copepods are among the most prevalent crustacean parasites affecting fish in a wide range of aquatic environments, including freshwater, brackish, and marine habitats. These parasites, particularly from families Ergasilidae and Lernaeidae, are significant contributors to fish diseases, impacting their health, growth, and productivity. Our study investigates the diversity and phylogeny of parasitic copepods in freshwater fishes across the Mediterranean (Portugal, Spain, Italy, Croatia, Bosnia and Herzegovina, Albania, Greece) and the Middle East (Turkey, Iraq). Extensive sampling, conducted between 2014 and 2023, examined 1,414 fish specimens representing 60 Mediterranean and 113 Middle Eastern species, resulting in the identification of over 1,100 parasitic copepod specimens. Key genera identified are Ergasilus von Nordmann, 1832, Neoergasilus Yin, 1956, Paraergasilus Markevich, 1937, Lamproglena von Nordmann, 1832, Lernaea Linnaeus, 1758, and Pseudolamproglena Boxshall, 1976. These findings include the discovery of a new species of genus Pseudolamproglena in Iraq, described using a combined morphological (light microscopy and SEM) and molecular approach (partial 18S rDNA, 28S rDNA, and COI sequences). Furthermore, new host records, localities and molecular data are provided for 8 known species – Ergasilus barbi Rahemo, 1982, Ergasilus briani Markevich, 1933, Ergasilus lizae Kroyer, 1863, Ergasilus sieboldi von Nordmann, 1832, Neoergasilus japonicus (Harada, 1930), Paraergasilus longidigitus Yin, 1954, Lamproglena pulchella von Nordmann, 1832 and Lernaea cyprinacea Linnaeus, 1758, while phylogenetic relationships within families Ergasilidae and Lernaeidae are discussed. |
