The genus Stygimys ("Styx mouse") was named by R.E. Sloan and Leigh Van Valen in 1965. The name comes from the Styx (river of hell) from Greek mythology. The genus has also been known as Catopsalis (partly); Cimexomys (partly); Eucosmodon (partly); and Parectypodus (partly). Some skull material is known, but not much.
