Results of the admixture analysis of all 49 individuals belonging to mtDNA clades I, II, and III. Analysis was performed using Structure 2.3.4 [34] with K = 3 where each cluster associates to one of the well-recognized species D. galeata (green), D. longispina (blue), and D. cucullata (purple); reference data are not shown. The population identification code as well as the corresponding mtDNA clade are given on the x axis and the posterior probabilities on the y axis. For information on population codes see Table 1
