Statistical support for nodes is provided as posterior probability values above nodes (> 0.95 PP) and bootstrap values below nodes (> 75%). An * or # denotes nodal relationships that were not supported (<0.95 PP/ <75%). Potamonautes sidneyi s.s. (clade 3) localities are marked with a dark blue triangle, while P. danielsi (clade 5) localities are marked by an orange square. The two new species, P. karooensis, (clade 2) and P. Ʋalles (clade 4), are marked by a light-blue circle and a green diamond, respectively. Specimens of P. barbarai are confined to clade 1.
