Morphometric and molecular characterization of Gyrodactylus spp. (Platyhelminthes: Monogenea) from Antarctic notothenioid fish
Original language description
Parasites of the genus Gyrodactylus von Nordmann, 1832 are tiny worms being distributed worldwide. Nearly 500 species have been described so far, of which 466 species can be considered as a valid species. Currently, only nine species of Gyrodactylus are known from notothenioid fishes in Antarctic area. A total number of 115 fish specimens of five species were collected during two Antarctic expeditions at the Czech Antarctic Station of Johann Gregor Mendel, James Ross Island (Prince Gustav Channel, Weddel Sea) between January 2013 and March 2014. Morphomentric and genetic analysis of collected material were perfomed at the laborary in the Czech Republic. Species indentification based on the morphometry of opisthaptoral hard parts in combination with nuclear rDNA sequences confirmed the presence of four species. The identified species were: Gyrodactylus antarcticus Gussev, 1967, Gyrodactylus cf. byrdi and Gyrodactylus coriicepsi Rokicka, Lumme, Zietara, 2009. The fourth species recorded from Trematomus bernacchii, Trematomus hansoni and Trematonus newnesi represent new species. Based on the ITS rDNA sequences the newly identified species resulted as a sister taxon to G. antarcticus. The phylogentic analysis based on the 18S rDNA showed that Antarctic species are more closely related to European Gyrodactylus spp. than those South American.
