Fig. 1. A Maximum Likelihood tree topology derived for the three mtDNA loci (12S rRNA +16S rRNA + COI) for the eastern and southern African freshwater crab genus Potamonautes, with the outgroups removed. Bootstrap values> 75% are indicated below each node while posterior probability values> 0.95 pP are shown above each node. An asterisk (*) above or below a node indicates the lack of statistical support. The new, as yet undescribed species from Hogsback is demarked as P. sp. nov. on the phylogenetic tree. Clades 1 and 2 refers to predominantly East African species, while clade 3 refers to the southern African clade.
