Bayesian phylogenetic tree inferred from combined genetic and phenotypic dataset, constrained. Fifty-percent majority rule consensus tree from Bayesian analysis of the combined genetic and phenotypic datasets, with topology constraints implemented as described in the text, as estimated in MrBayes. Node values are Bayesian posterior probability support values; only values above 90% are shown. Scale bar represents substitutions/site. Colored boxes indicate major clades. Fossil taxa are marked with a dagger (†). Grayed taxon names indicate extant species that are included on the basis of phenotypic data only.
