Pseudocrangonyx cavernarius sp. nov. (Amphipoda, Pseudocrangonyctidae) from Huayangdong Cave in Anhui Province, China is described. The new species can be distinguished from its congeners by the inner plate of maxilla 1 having four setae, the outer ramus of uropod 2 being about 66% of the length of the inner ramus, the ramus of uropod 3 being about 3.25 times as long as the peduncle and the telson being cleft for one-fifth of its length. The affinity of Pseudocrangonyx cavernarius to related species is discussed.
