Bunomys fratrorum (Thomas, 1896) . Ann. Mag. Nat. Hist., ser. 6, 18:246.

TYPE LOCALITY: Indonesia, NE Sulawesi, Rurukan, 3500 ft .

DISTRIBUTION: Sulawesi; NE peninsula only.

COMMENTS: Despite Thomas' clear declaration that fratrorum was distinct from chrysocomus, an evaluation also supported by Tate (1936) and Sody (1941), fratrorum was listed as a synonym of chrysocomus by Ellerman (1949a) and Laurie and Hill (1954). The two are sympatric on the NE peninsula (Musser, 1970d, 1981c, 1991; Musser and Newcomb, 1983). Sody (1941) made fratrorum the type species of Frateromys .
