Bayesian tree for mitochondrial haplotypes of the heterodermus subgroup (sensu Williams et al. 1996). Each individual haplotype bears the letter M meaning mtDNA, followed by a letter for the respective clade and a number. Major clades and major lineages are identified by roman numbers I, III, and II, respectively. Support values are Bayesian posterior probabilities and thorough 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.
