Phylogenetic tree of 29 Dactylogyrus species (hosts in brackets) constructed by Bayesian Inference (BI). The tree is based on the combined DNA sequences of partial genes coding 18S rRNA, 5.8S rDNA, 28S rRNA and the entire ITS1 region. Values along branches indicate posterior probabilities and bootstrap values for each node resulting from Bayesian Inference and Maximum likelihood (ML) analyses, respectively. Values <0.80 for BI and <50% for ML are indicated by dashes.
