BEAST analysis of the nuclear genes with a truncated normal calibration prior. For analytical details see the manuscript. Tip labels for all taxa newly sampled in this analysis, Linnaean binomials were used. For all taxa sampled in previous work, sample codes were used to match voucher references in other works; for these refer to Folk et al., Systematic Biology, 66(3): 320โ337; refer also to the associated Dryad deposition, https://doi.org/10.5061/dryad.cd546 (in which see Online Appendix 1)
