The maximum clade credibility tree estimated with BEAST 2, based on concatenated genes carrying SNPs. a Chromosome. b pSymB. c pSymA. d All concatenated genes carrying SNPs. Node bars indicate the 95 % credible intervals (95 % HPD) for node ages, and posterior probabilities (>0.5) are indicated (in italics) on the branches. Relevant node ages (years) and clades are indicated. The root of the unrooted tree was placed at the mid-point of the longest distance between two taxa in the tree
