Maximum likelihood phylogenetic analyses based on 845 loci and the complex LG+C60 mixture model. UFBoot2 and an SH-like aLRT branch support test were employed. A dot labels full branch support; a colored halo around the dots labels the support indices for major clades. For additional assessment of robustness (gene jackknife and topology tests), seeFigures S1B and S1C; a time-calibrated tree is shown inFigure S2.
