| Description | The Gyrodactylus nemachili-like species complex parasitizing stone loach in the Czech Republic was investigated based on the detailed morphometric analysis of the hard parts of the parasite haptor. The existence of two species, Gyrodactylus jiroveci Ergens & Bychowsky 1967 and Gyrodactylus pseudonemachili Ergens & Bychowsky 1967 was confirmed. A standard discriminant analysis of the morphometric data showed a clear separation between specimens of G. jiroveci and another species or variant. Based on the morphology of the haptoral hard parts, this third species was more similar to G. jiroveci than G. pseudonemachili. Based on comparison with the original archived material the third species was identified as Gyrodactylus papernai Ergens & Bychowsky 1967 recently considered as a synonym of G. jiroveci. These analyses provided sufficient evidence for the restoration of G. papernai to species level. Partial sequences of the internal transcribed spacer rRNA genes (ITS rDNA) verified validity of all three Gyrodactylus species studied. |
