Tanglegram comparing mitochondrial and concatenated nuclear phylogenies, optimized in Dendroscope to minimize line crossings. Again, the concatenation tree is used to represent the nuclear phylogeny in order to maintain comparability and to show divergent placement of subspecific samples in the mitochondrial tree. In order to minimize spurious disagreement between phylogenies due to estimation error, all clades with < 70% bootstrap support have been collapsed
