FIGURE 1. Timing of cladogenesis based on concatenated COI, 16S, and 28S data, as derived from analysis on BEAST calibrated using the fossil record and the final closure of the Panama Isthmus (adapted from Coppard et al. 2013). Ages of stages and epoch series are based on International Commission on Stratigraphy stratigraphic chart (Cohen et al. 2012). Error bars estimated by BEAST are shown in light blue. Colours of clades indicate geographic range (red = Atlantic and Caribbean, blue = eastern Pacific, green = Gulf of California).
