Melomys aerosus (Thomas, 1920) . Ann. Mag. Nat. Hist., ser. 9, 6:428.

TYPE LOCALITY: Indonesia, Pulau Seram, Mt Manusela, 6000 ft .

DISTRIBUTION: Endemic to Seram Isl.

COMMENTS: Tate (1951:292) suggested a relationship between M. aerosus and the New Guinea M. levipes group, but cranial morphology indicates M. aerosus to be more closely related to Australian species of Melomys, especially M. cervinipes, than to the endemic Melomys of New Guinea (data from specimens in the British Museum of Natural History).
