Rattus bontanus Thomas, 1921 . Ann. Mag. Nat. Hist., ser. 9, 7:246.

TYPE LOCALITY: Indonesia, SW Sulawesi, Mt Bonthain (Gunung Lampobatang), 2000 ft .

DISTRIBUTION: Known only from 600-2500 m on the slopes of Gunung Lampobatang, SW Sulawesi.

COMMENTS: Sody (1941) questionably included this species in Taeromys, Laurie and Hill (1954), and Musser (1984) treated it as a subspecies of R. xanthurus, but Musser and Holden (1991) contended that it is a distinct species most closely related to R. foramineus, which occurs in coastal lowlands of the southern end of the SW peninsula of Sulawesi.
