Mallomys rothschildi Thomas, 1898 . Novit. Zool., 5:2.

TYPE LOCALITY: Papua New Guinea, Central Prov., Owen Stanley Range, between Mt Musgrave and Mt Scratchley, 5000-6000 ft (Flannery et al., 1989 provided additional data) .

SYNONYMS: argentata, weylandi.

COMMENTS: M. rothschildi and M. aroaensis are thought to be sympatric at a few localities (Flannery et al., 1989), but the morphological variation present among samples requires re-examination to test whether it reflects presence of one or two species.
