Bayesian tree for the complete genetic evidence data set (mtDNA + nDNA) of the heterodermus subgroup (sensu Williams et al. 1996). Clades/lineages are indicated on the right. Support values are Bayesian posterior probabilities and ML bootstrap values. Values not shown for nodes with < 0.75 posterior probabilities and < 50% bootstrap support. Colour code as in Figure 1. Outgroup Polychrus marmoratus removed for clarity.
