Analyses of the small subunit ribosomal RNA gene sequences of the representatives of major taxa of Monophisthocotylea was performed to identify the sister group of Gyrodactylus. Nuclear ribosomal DNA sequences from the complete internal transcribed spacer (ITS) region were used to infer phylogeny of thirty-seven Gyrodactylus species and Gyrodactyloides bychowskii, Macrogyrodactylus polypteri and Gyrdicotylus gallieni, using maximum likelihood, parsimony and Bayesian inference. The genus Gyrodactylus appeared to be a monophyletic group in all analyses.However, none of the six subgenera appeared to be monophyletic, and the most basal subgenus G. (Gyrodactylus) was paraphyletic. Characteristics of the excretory system of Gyrodactylus as presented by Malmberg (1970) do not seem to be informative enough to reveal subgenera within Gyrodactylus. Also, the characteristics are difficult to use as the excretory system is unknown in the majority of newly described species and we suggest abandoning existing subgenera as indicators of phylogeny. The grouping of species based mainly on the morphology of the ventral bar and marginal hooks seems to have sufficient power to inform us about relationships between the Gyrodactylus species. However, comprehensive revisions in some species groups are required.
