Maxomys inas (Bonhote, 1906) . Proc. Zool. Soc. Lond., 1906:9.

TYPE LOCALITY: Malaysia, Perak (Malay Peninsula), Gunung Inas .

DISTRIBUTION: Endemic of Malay Peninsula (and possibly Peninsular Thailand south of Isthmus of Kra) in montane forests, rarely occurring below 3000 ft (Medway, 1969).

COMMENTS: Once treated as a subspecies of alticola (Chasen, 1940), but identified as a separate species by Medway (1964). A close phylogenetic ally to M. whiteheadi, as indicated by morphological, biochemical, chromosomal, and spermatozoal traits (Breed and Yong, 1986; Chan et al., 1978, 1979; Yong, 1969).
