| Abstract: | Pseudocrangonyx cavernarius sp. nov. (Amphipoda, Pseudocrangonyctidae) from Huayangdong Cave in AnhuiProvince, China is described. The new species can be distinguished from its congeners by the inner plate of maxilla 1 havingfour setae, the outer ramus of uropod 2 being about 66% of the length of the inner ramus, the ramus of uropod 3 being about3.25 times as long as the peduncle and the telson being cleft for one-fifth of its length. The affinity of Pseudocrangonyx cav-ernarius to related species is discussed. |
