Figure 7
Statistical parsimony network showing the mutational relationships among the analysed mitochondrial COI haplotypes of Pterostichus nigrita (green) and Pterostichus rhaeticus (blue). Each line in the network represents a single mutational change; small black dots indicate missing haplotypes. The numbers of analysed specimens (n) are listed; the diameter of the circles is proportional to the number of haplotypes sampled (see Open circles with numbers). Images were obtained from http://www.eurocarabidae.de.
