Phylogenetic position of Rapaza viridis n. gen. et sp. within the Euglenozoa as inferred from SSU rRNA gene sequences. Maximum-likelihood (ML) tree constructed using TIM1ef + G model of evolution on an alignment of 39 taxa and 805 unambiguously aligned sites, including 298 constant positions and 432 informative positions, using seven kinetoplastid and three diplonemid sequences as the outgroup. ML bootstrap values greater than 50% are shown. Thick branches indicate Bayesian posterior probabilities (PP) over 0.95. The branch leading to the fast-evolving Entosiphon clade has been shortened by one half (indicated by '1/2').
