Fig. 2. Phylogenetic position of the present Dactylogyrus species based on 28S rDNA sequences. Distances were estimated using Kimura two-parameter model. The tree was constructed using the neighbor-joining method. The tree was identical to that obtained using maximum-parsimony and the numbers along branches represent bootstrap values given as above branch NJ and lower branch MP. Bootstrap support (> 50 % for 1,000 replicates) is shown at each node.
