Maximum Parsimony and Bayesian Inference tree topology based on 18S rDNA, 28S rDNA, 12S rDNA, and COI datasets combined. Posterior probabilities are above the node and jackknife values are below the node. Branch lengths in orange corresponds to terrestrialism, branch lengths in blue correspond to traditional members of the family Hirudinidae, and branch lengths in green correspond to traditional members of the family Haemopidae.
