摘要：

A new species of freshwater crab, Potamonautes amathole sp. nov., is described from the WinterbergAmathole mountain range in the Eastern Cape Province, South Africa. Morphologically, P. amathole Peer & Gouws, sp. nov. most closely resembles P. tuerkayi but can be distinguished by key morphological characters including the variation in the shape of the subterminal segment of gonopod 2 between both species. Genetically, P. amathole Peer & Gouws, sp. nov. is placed within the clade of small-bodied, mountaindwelling crabs including P. parvispina, P. parvicorpus, P. brincki, P. tuerkayi, P. baziya, and P. depressus. The new species is found in slow-moving mountain streams and pools at high altitudes. The continued discovery and description of new freshwater crab species reinforces the need for ongoing research, especially in under-sampled regions.
