Maxomys inas (Bonhote 1906)

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

Type Locality: Malaysia, Perak (Malay Peninsula), Gunung Inas.

Vernacular Names: Malayan Mountain Maxomys.

Distribution: Endemic of Malay Peninsula (and possibly peninsular Thailand south of Isthmus of Kra) in montane forests, rarely occurring below 3000 ft (914 m; Medway, 1969).

Conservation: IUCN – Lower Risk (lc).

Discussion: Once treated as a subspecies of Bornean M. 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). Maxomys inas joins Niviventer cameroni and Pithecheir parvus as the three living endemic murines on the Malay Peninsula south of the Isthmus of Kra (Musser, 1986; see account of Niviventer cameroni).
