Fig. 3. Best Maximum Likelihood tree based on the data set of concatenated 12S and 16S rDNA, and c-mos sequences. The red clade depicts the Helicops angulatus group. On the left and right sides of a slash (/) are values indicated at nodes for Maximum Likelihood bootstraps (> 75%) and Bayesian Posterior probability values (> 95%), respectively. Green clades represent the paraphyly of Helicops angulatus. The name Helicops pictiventris is currently a junior synonym of H. infrataeniatus, but it appears in the tree exactly as the pertinent sequences appear in the GenBank dataset.
