Gyrodactylus chileani n. sp. is the first Gyrodactylus species reported from Chile. It is an ectoparasite living on fins and skin of a small fish, the Chilean tidal pond dweller Helcogrammoides chilensis (Cancino) (Perciformes: Tripterygiidae). A phylogenetic analysis based on 5.8S+ITS2 of rDNA placed the new species close to marine Gyrodactylus species found in Europe: G. orecchiae Paladini, Cable, Fioravanti, Faria, Cave %26 Shinn, 2009 on gilthead seabream Sparus aurata L. from the Adriatic and Tyrrhenian Sea fish farms (Perciformes: Sparidae), and an undescribed species on the black goby Gobius niger L. from the North Sea (Perciformes: Gobiidae). A morphological description of the latter species is unavailable. These geographically distant parasite samples on different host families form a new well supported Gyrodactylus orecchiae lineage. Using molecular phylogenetics, it is shown that the marine species groups of Gyrodactylus may have a worldwide distribution.
