3.5. Phylogenetic positioning of G. diptychi n sp.

To investigate the relationship of G. diptychi n. sp. to other Gyrodactylus members, we used BI and ML methods to construct the phylogenetic trees, using ITS1-5.8S-ITS2 gene sequences, of G. diptychi n. sp. and Gyrodactylus members. As shown in Fig. 5 , BI and ML analytic methods yielded two similar phylogenetic trees with minor variations in statistical values. Gyrodactylus diptychi n. sp. formed a clade with G. gymnodiptychi , G. tayshirensis , G. papernai , G. nemachili , G. pseudonemacheili , and G. mongolicus . Both phylogenetic trees indicated that G. diptychi n. sp. was closely related to Gyrodactylus members and belonged to the subgenus Limnonephrotus Malmberg, 1964 .
