Coding of each collection locality is given on the upper left, same localities were tested in the Ancestral area reconstruction analysis (AAR). For respective deep nodes the results of AAR are given, and divergent time estimates are displayed on respective nodes with error bars for node ages of 95% highest posterior density intervals. Colored dots in respective terminals indicate the collection locality for each specimen.
