Phylogenetic tree of 66 sequences of various haemogregarine taxa reconstructed by Bayesian inference. The tree is based on a 614 bp-long alignment of ortholog partial 18S rDNA sequences and is rooted using Adelina dimidiata and Klossia helicina as outgroup. Values at the nodes indicate posterior probabilities (>70) from the Bayesian inference, and bootstrap values (>50) from the maximum likelihood analysis. Lower values are shown as dashes (–). The length of branches represents the number of substitutions per site. Newly generated sequence of Dactylosoma cf. ranarum SK collected from Slovakia is in red. GenBank accession numbers are in parentheses at the taxa name.
