Phylogenetic tree based on A mitochondrial Cyt b (1140 bp) and B the corresponding ranges of the three clades. In this phylogenetic tree, Bayesian posterior probabilities (BPP) from BI analysis/ultrafast bootstrap supports (UBP) from ML analysis are noted beside nodes. Scale bars represent 0.05 nucleotide substitutions per site. The numbers at the tips of branches correspond to the ID numbers listed in Table 2.
