Stenomys niobe (Thomas, 1906) . Ann. Mag. Nat. Hist., ser. 7, 17:327.

TYPE LOCALITY: Papua New Guinea, Angabunga River, Owgarra, 2750 m .

DISTRIBUTION: New Guinea, nearly all montane regions, including the Huon Peninsula (see map in Taylor et al., 1982:191).

COMMENTS: Revised by Taylor et al. (1982), who recognized two distinct subspecies, arrogans and niobe . Flannery (19906:241), however, noted that unpublished results from biochemical studies indicated that two species are present in what Taylor et al. (1982) defined as a single species, one at high altitudes, the other at lower altitudes. Chromosomal morphology presented by Dennis and Menzies (1978). Phallic anatomy discussed by Lidicker (1968).
