Table 1. Comparison of the divergence dates for the various clades (indicated on figure 2), and species under different speciation models (tree priors) in BEAST. The mean date estimates are given in millions of years (Ma) and the confidence intervals (based on the 95% highest posterior density – HPD) are given in parentheses. The species complex referred to is that between S. erythrognathus andS. karooensis .
