Figure 2. Maximum clade credibility tree from the BEAST analysis of CO1, 16S and EF-1ɣ for the Stasimopus specimens occurring in the Karoo under the birth-death speciation model. The grey bars indicate the confidence intervals for the dating. Outgroups available in Table S5. Posterior probabilities above 0.70 are given on the corresponding nodes. Specimen numbers correspond to localities in Figure 1, and red specimens indicate juveniles which could not be identified. Identified species are indicated by the coloured bars. Clades are numbered for the ease of discussion. Discussed nodes are indicated by roman numerals.
