Summary of values obtained from approximately unbiased test.

Values are comparing our best phylogeny against phylogenies where proposed relationships were constrained. None of the hypotheses can be rejected, since all p values are above the 0.05 threshold. wkh – weighted Kishino-Hasegawa test; au – approximately unbiased test; wsh – weighted Shimodaira-Hasegawa test; FD – taxon as defined in Fiore-Donno et al. [22]; S – taxon as defined in Smirnov et al. [15]; CS – taxon as defined in Cavalier-Smith et al. [14].
