mtDNA tree. Bayesian inference tree based on the mitochondrial control region sequences. The mtDNA-lineages defined by Sturmbauer et al.  are indicated above branches, and their approximate distribution around the lake (adapted from ) is shown in the map (top left). Posterior probability values are shown near the respective nodes. The bars on the right-hand side show the assignment of the samples to (A) colour lineages  and (B) to the species classification suggested by Konings . Same-coloured bar sections spanning paraphyletic clades are divided by thin black lines to indicate the inconsistency with the tree topology.
