摘要：
A new species of river crab, Potamonautes granularis sp. nov., from the lower reaches of the Olifants River, South Africa is described and illustrated. The orange tips of the chelipeds and the granulation of the postfrontal crest can distinguish this species from other freshwater crabs in the area. The morphological differences between P. granularis sp. nov., P perlatus, and P. sidneyi are investigated and quantified and the new species is compared with other freshwater crabs from the region.
