Abstract

Four species of freshwater crabs from three genera and two families ( Cantopotamonhengqinense Huang, Ahyong & Shih, 2017, Nanhaipotamonguangdongense Dai, 1997, Nanhaipotamonmacau sp. n. , and Somanniathelphusazanklon Ng & Dudgeon, 1992) are documented from Macau for the first time. One new species, Nanhaipotamonmacau sp. n. , is described. The large flap on the male first gonopod terminal segment sets it apart from all other known congeners except N.wupingense Cheng, Yang, Zhong & Li, 2003, from Fujian. Characters of the carapace, male first gonopod and size, however, clearly differentiate these two species. Preliminary genetic studies also suggest that the two are not closely related. A neotype is designated for N.wupingense . The taxonomic status of Nanhaipotamonguangdongense is also discussed. Notes on the general biology and conservation status of these crabs are also included.
