Best tree of the Spirotrichea inferred by Maximum likelihood of Dataset Atub_n74.

<p>Species newly sequenced in the present study are shown in bold type. Bootstrap values for branches of the ML tree and posterior probability values for BI tree, respectively, are given on nodes. Fully supported (100%/1.00) branches are marked with solid circles. The scale bar corresponds to 10 substitutions per 100 nucleotide positions. Dargyrome patterns and natural habitats are given after species name of euplotids by symbols. Clades I-IV for euplotids were designated according to Petroni <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040635#pone.0040635-Petroni1" target="_blank">[42]</a> and Yi et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040635#pone.0040635-Yi4" target="_blank">[38]</a>.
