  1. Date priors for the common ancestor of Acacia thrips and a parallel divergence event used to calibrate the thrips phylogeny. Path and stepping-stone sampling were used to estimate marginal likelihoods of each the divergence timing model for Bayes factor tests. A split in the thrips and Acacia phylogenies was treated as fixed [89].
