Figure 4.

Nested statistical parsimony cladograms of COI haplotypes. White circles represent haplotypes. Their diameter is proportional to the number of individuals carrying that haplotype. Unsampled or extinct haplotypes are depicted as small black circles. Connection lines between haplotypes correspond to a single base substitution. Haplotypes united in 1-step clades are highlighted by light grey, two step clades by dark grey areas. The 3-step clades are separated by hatched lines, 4-step clades by solid lines. A) The 4-step nested cladogram of T. villosus and B) the 3-step cladogram of S. mucronata.
