FIGURE 2. Median–joining network illustrating genealogical relationships among haplotypes of concatenated mtDNA (Cyt b+NADH2+COI) (1671 bp). The size of each haplotype circle is proportional to its frequency. Small intermediate circles represent median vectors of either unsampled or extinct taxa. Numbers indicate mutational steps between haplotype (one, if not shown). Color–coded by haplotypes between geographical locations.
