  1. Divergence times estimated by BEAST based on either total evidence (mitochondrial and nuclear) or nuclear only datasets. Divergence time estimates are the median age of the posterior distributions in million years of age and the 95% highest posterior density (HPD) intervals are indicated in brackets. Label numbers refer to the topology of Figure 4.
