Figure. Bayesian inference phylogenetic analysis of selected human diphyllobothrideans based on cox1 gene analyzed as 3 independent data parts according to the nucleotide coding positions by using (GTR+G)(HKY)(GTR+G) evolutionary model setup in MrBayes (mrbayes.sourceforge.net). Topologies sampled every 1,000th generation over 4 runs and 20,000,000 generations, burn-in 25%. Diphyllobothrium pacificum identified in Spain marked in gray; new sequence is in bold type. Scale bar indicates nucleotide substitutions per site.
