Time-calibrated phylogeny of scorpions in the genus Kovarikia inferred from 414,566 base-pairs of concatenated RAD loci. Nodes that received less than 1.0 posterior probability support are labeled and in bold. Mean estimated divergence date (in millions of years ago, Ma) followed by 95% highest posterior density intervals in brackets. SBM = San Bernardino Mountains, SJM = San Jacinto Mountains.
