Median-joining network of 149 sequences of 687 bp of CYTB from 36 populations. Length of branches is proportional to the number of substitutions along a given branch, and circle size is proportional to haplotype frequency. Haplotypes from three main genetic groups (LimpS, LimpN, Chefu) are enclosed by circles of different colours. Private haplotypes from the easternmost localities in the Chefu basin (Pop225 and Pop423) are in red. Green arrows indicate haplotypes co-occurring in Pop406 (haplotypes h16, h17, and h24).
