A Bayesian Inference phylogram and divergence time estimation for the three mtDNA loci (12S rRNA +16S rRNA + COI) for the eastern and southern African freshwater crab genus Potamonautes MacLeay, 1838, with outgroups removed. Bootstrap values> 75% are indicated below each node while posterior probability values> 0.95 pP are shown above each node by an asterisk (*). Where no asterisk is present no support for a node was obtained. Blue polygons on branches indicates species present, on Mozambique 'sky islands'.
