Fig 1. Maximum likelihood tree resulting from the 58 concatenated protein-coding genes common to 14 representative taxa.

The BI tree had identical topology with the ML tree. The GTR+I+G model was selected based on Modeltest. The bootstrap support values of the ML tree and the posterior probabilities of the BI tree at all nodes are 100% and 1.00, respectively, except for one node marked by an asterisk, which has a value of 99% and probability of 1.00. ψ, pseudogene; †, partial gene sequence.
