Optimal phylogenetic trees (branch lengths arbitrary) derived from combined GHR-morphology-indel dataset using A) MrBayes with HKY+G model for GHR partition (majority rule consensus of 9901 post-burnin trees from run #1; support indices represent Bayesian posterior probabilities) and B) MP with equally weighted data (strict consensus of 8 trees at 957 steps; support indices represent bootstrap values from 500 pseudoreplicates of a simple addition sequence, not reported under 50). Numbers adjacent to chrysochlorid taxa represent coding of mallear head, corresponding to the character states illustrated in Fig. 5 (data missing for some species of Amblysomus). Colored letters adjacent to clades correspond to the partitioned branch support analysis presented in Table 1. Green = positive HBS, red = negative HBS, black = additive HBS (see Table 1).
