Fig. 4 Haplotype network based on COI. Each black circle represents a different haplotype; their size is proportional to the number of samples belonging to that haplotype. Each perpendicular line indicates a mutational step; if there were more than four, it is shown with the number of mutational steps. White circles are hypothetical intermediate haplotypes. Branch length does not contain any information
