Solomys Thomas, 1922 . Ann. Mag. Nat. Hist., ser. 9, 9:261.

TYPE SPECIES: Uromys sapientis Thomas, 1902 .

SYNONYMS: Unicomys .

COMMENTS: Member of the New Guinea region Old Endemics (Musser, 1981c). Included in Melomys by Ellerman (1941:226), then transferred to Uromys by Tate (1951:312), but finally recognized again as a distinct genus (Flannery and Wickler, 1990; Laurie and Hill, 1954:128). Presumably related to Uromys and Melomys, but no adequate diagnosis and definition of the genus and assessment of its phylogenetic relationships is yet available.
