Figure 1.

Time-calibrated phylogeny for the major Cryptoblepharus lineages based on a summary-coalescent species tree analysis of 1225 loci. Confidence intervals for the node ages are highlighted in grey. The geographical region of origin has been annotated for each species using coloured orbs (see legend). Moreover, internal nodes have been annotated with the most probable ancestral regions as inferred using ancestral range estimation (see the electronic supplementary material, figure S2 for further details) and the colour scheme corresponds with figure 2. All nodes with multi-locus bootstrap support below 90 have been annotated and the blue arrow highlights the inferred branch where species switched from a non-coastal to coastal habitat (also see the electronic supplementary material, figure S3).
