Note: Supported clades are stable across analyses, albeit with decreasing support as the percentage of missing data increases. Bootstrap support values from RAxML analyses. Support values greater than 75 are indicated by bold text and greater than 85 are indicated with a. nm = nonmonophyletic. Column headings describe the data sets. For example, “10:16” includes all taxa that have at least 10 of the 16 genes, with a total of 88 taxa representing 26 lineages and containing 17% missing data. The “all:15” includes the protein-coding genes from all taxa and contains 59% missing data. See Table S2 for lineages and Figure S1a–h for individual trees.
Support values greater than 85.
