<p>Bootstrap support values (> 50%) are indicated above the branches (posterior values from the corresponding Bayesian analysis are provided below the branches;-: node not recognized). The populations of the same species clustering together are indicated in a grey box. The definitions of clades follow those of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132596#pone.0132596.g001" target="_blank">Fig 1</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132596#pone.0132596.g002" target="_blank">Fig 2</a>.
