Maximum-likelihood tree based on partial <i>cox1</i> sequences of 95 <i>Xerocrassa mesostena</i> individuals and <i>X. subvariegata</i> and <i>X. grabusana</i> as outgroups.

<p>Haplotype clades are labelled to the right of the tree. Bootstrap support values larger than 75% are indicated by asterisks above the branches. For each individual the AFLP cluster as delimited using STRUCTURE is indicated by the same colour as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0062569#pone-0062569-g002" target="_blank">Figure 2</a>.
