Niviventer cremoriventer (Miller 1900)

[Niviventer] cremoriventer (Miller 1900) , Proc. Biol. Soc. Wash., 13: 144.

Type Locality: S Peninsular Thailand, Trang Province, Trang (07E30'N, 99E18'E).

Vernacular Names: Sundaic Arboreal Niviventer.

Synonyms: Niviventer barussanus (Miller 1911) ; Niviventer cretaceiventer (Robinson and Kloss 1919) ; Niviventer flaviventer (Miller 1900) ; Niviventer gilbiventer (Miller 1903) ; Niviventer kina (Bonhote 1903) ; Niviventer malawali ( Chasen and Kloss 1932) ; Niviventer mengurus (Miller 1911) ; Niviventer solus (Miller 1913) ; Niviventer spatulatus ( Lyon 1911) ; Niviventer sumatrae ( Bartels 1937) .

Distribution: Peninsular Thailand and Malaya and some offshore islands; Mergui Arch., Anambas Isls; Sumatra, and smaller islands of Nias, Billiton and Banka; Borneo and some offshore islands, Java, and Bali; see Musser (1973 c) and Corbet and Hill (1992). Does not occur north of the Isthmus of Kra (10E30'N).

Conservation: IUCN – Lower Risk (lc).

Discussion: Revised by Musser (1973 c, 1981 b); a Sundaic endemic whose closest morphological and likely phylogenetic relative is the Indochinese N. langbianis . Considerable variation in body size exists among samples, with those in small island populations being larger than individuals in populations on larger islands and the Malay Peninsula ( Musser, 1973 c). Tuen et al. (2000) documented N. cremoriventer from peninsular Mt Santubong in W Sarawak, and Md Nor (1996) recorded its distribution and ecology on the small islands off N tip of Sabah. This generally lowland species reaches 1530 m on the slopes of Mt Kinabalu in Sabah ( Md Nor, 2001, and references cited therein). Niviventer cremoriventer joins N. rapit as the only two species in the genus occurring on Borneo.
