Phylogenetic tree yielded by ML and Bayesian analyses of 13 mitochondrial protein-coding genes. Bayesian consensus tree is shown with support indicated by numbers at branches, representing Bayesian posterior probabilities (BPP) and ML bootstrap (BS) support values, respectively. Scale bar represents the estimated number of substitutions per site. Bars on the right represent mt genome size and composition, as well as total intron number for each taxon
