Phylogenetic trees obtained from the Bayesian inferences and maximum–likelihood analyses. a The congruent topology from the analysis of ML–PCG (BP in left), ML–PCG12 (BP in middle), and ML–PCG12R (BP in right); b The congruent topology from the analyses of ML–PCGR (BP in left), BI–PCG (PP in middle), and BI–PCGR (PP in right); c The congruent topology from the analyses of BI–PCG12 (PP in left), BI–PCG12R (PP in right). Values at node represented the Bayesian posterior probabilities (PP) or bootstrap probabilities (BP). We showed a schematic version of the trees (b–c) with some ingroups collapsed and outgroups removed for clarity
