Figure 10. Haplotype network of Pseudothyretes spp. constructed using the 61 mitochondrial cytochrome c oxidase subunit I (COI) sequences obtained. The size of the circles is proportional to the haplotype frequency (empty circles represent sizes for one, two, four, and eight individuals). The median vectors that represent hypothetical intermediates or un-sampled haplotypes are shown in black circles. Black dots on particular branches represent nucleotide substitutions between particular haplotypes. Analyses were conducted with the median-joining method in NETWORK 4.6.1.1.
