Maxomys moi (Robinson and Kloss, 1922) . Ann. Mag. Nat. Hist., ser. 9, 9:95.

TYPE LOCALITY: Vietnam, Lang Bian Mtns, Arbre Broyé, 5400 ft .

DISTRIBUTION: Endemic to S Vietnam and S Laos.

COMMENTS: Originally described as a species by Robinson and Kloss (1922), later listed as a subspecies of either surifer or coxingi, but finally shown to be a distinct species (Musser et al., 1979; Van Peenen et al., 1969). Closest phylogenetic relative is M. surifer, an estimate based on cranial, dental, and chromosomal traits shared by both species (Duncan and Van Peenen, 1971; Musser et al., 1979).
