| Abstract: | A Gyrodactylus species from northwestern Sweden is described. Because only one specimen of the species was found no specific name is given. The type of protonephridial system of the new species showed that it belongs to the subgenus G. ( Paranephrotus ). Because of the strong resemblance between the new species and G. hrabei Ergens these two species are placed in a new species group: the G. hrabei-group. The Eurasian fresh water fauna seems to have very few representatives belonging to G. ( Paranephrotus ) and because of this the above find is of special interest. |
