20. Bayesian tree of members of Herpetomonas and Phytomonas. The tree was built on the unmodified character matrix of 23 Herpetomonas and 3 Phytomonas sequences (1,904 columns) employing the GTR + I + G model. Numbers associated to each node correspond to posterior probability and Maximum Likelihood bootstrap values. The scale bar represents an estimated sequence divergence of 4%. Underlined is the sequence of the trypanosomatid flagellate of Euplotes encysticus Ind3.
