Phylogenetic trees of Polyneoptera based on the dataset of PCG12RNA. (A) Bayesian phylogram of Polyneoptera. The numbers at the nodes refer to Bayesian posterior probabilities (BPP) and ML bootstrap support (BS) values. Nodal support values of 1.00 for BPP or 100% for BS are represented by “*”; BS values below 50% are represented by “ < ”. The solid red branches are not supported by the ML method; their positions under the ML method are indicated by dashed red branches with BS shown around. The dashed red branches are not scaled to their lengths. (B) Bayesian cladogram after removing Aposthonia japonica (Embioptera). Only a partial tree is displayed because the other branching patterns remain invariable.
