FIGURE 3. Median-joining haplotype network of 82 COI sequences belonging to 15 species of Ponticola including P. hircaniaensis sp. nov. The haplotype of hybrid individuals is marked with a star inside. Circle sizes depict frequencies of haplotypes; the smallest corresponds to one. Small black circles correspond to missing/hypothetical haplotypes. Numbers represent mutational steps between neighboring haplotypes; lines without mutation numbers indicate one mutational step.
