Figure 2 in Renewed sampling of inland aquatic habitats in southern Africa yields two novel freshwater crab species (Decapoda: Potamonautidae: Potamonautes)
Figure 2. Combined Bayesian tree topology derived from the total evidence mitochondrial DNA data set for the three loci: 12S rRNA, 16S rRNA, and COI. Values above the nodes represent bootstrap values (%) for the nodes, whereas values below the nodes represent posterior probability values (pP). Only bootstrap values> 75% are shown and posterior probability values of 1.00 are shown; NS, nodes that were not statistically supported.
