Bootstrap and posterior probability values from different phylogenetic methods as well as ages for nodes, heights and confidence intervals on the phylogenetic tree presented in Fig. 2 (major lineages are indicated in bold).

1Abbreviations: Aus: Australia, NZ: New Zealand, SAm: South America, MP: maximum parsimony, MPw: weighted maximum parsimony, ML: maximum likelihood.
2PP: posterior probability; L: 95% Lower Highest Posterior Density, U: 95% Upper Highest Posterior Density.

1. 缩写说明：Aus为澳大利亚（Australia），NZ为新西兰（New Zealand），SAm为南美洲（South America），MP为最大简约法（maximum parsimony），MPw为加权最大简约法（weighted maximum parsimony），ML为最大似然法（maximum likelihood）。
2. PP为后验概率（posterior probability）；L代表95%最高后验密度下限（95% Lower Highest Posterior Density），U代表95%最高后验密度上限（95% Upper Highest Posterior Density）。
