After total genomic DNA was extracted, complete cytochrome b (cyt b) gene and 11 microsatellite loci were examined for all sampled individuals. Based on the cyt b sequences, phylogenetic analyses with maximum likelihood and Bayesian inference methods were conducted and a median-joining haplotype network was calculated.The divergence time between major lineages was estimated using BEAST. Genetic structure based on the microsatellite dataset were also analyzed to detected admixture between major lineages in the mixed region.
