  1. Lengths of optimal internal branches are given in number of steps. Bootstrap percentages (BP) were obtained using phylogenetic reconstructions under maximum parsimony (MP) and maximum likelihood (ML). Bremer support or decay index (DI) was implemented in MP. Support for the Bayesian analysis (BA) was given by Bayesian posterior probabilities (BPP). BP and BPP were estimated under 50% majority-rule consensus. Star (*) indicates that the node was not recovered or was not supported in the corresponding analysis. Support values within Zander's [50] 0.95 binomial confidence intervals (CI) are highlighted in bold face.
