Amurocrangonyx n. gen. is described on the basis of recently collected specimens of Crangonyx arsenjevi (Derzhavin, 1927), a very poorly known subterranean amphipod crustacean originally described from springs in the Khor River basin of the Ussury River drainage in the Russian Far East. The species is redescribed from specimens obtained from the type-locality, Orekhovy spring, and a neotype is designated. A careful examination of the newly acquired material, although closely similar morphologically to Crangonyx, suggests that it represents a new genus in Crangonyctidae. However, determination of the precise phylogeographic relationship of Amurocrangonyx to Crangonyx or to other crangonyctoid genera in East Asia is unclear and must await molecular analyses.
