Sundamys infraluteus (Thomas 1888)

[Sundamys] infraluteus (Thomas 1888), Ann. Mag. Nat. Hist., ser. 6, 2: 409.

Type Locality: Malaysia, Sabah (N Borneo), Kinabalu.

Vernacular Names: Mountain Sundamys.

Synonyms: Sundamys atchinus (Miller 1942) .

Distribution: Gunung Kinabalu, 920-2930 m (Md Nor, 2001), and Gunung Trus Madi in Sabah; W mountain chain of Sumatra, 700-2400 m.

Conservation: IUCN – Lower Risk (lc).

Discussion: A montane species related to S. muelleri, which occurs at middle altitudes and lowlands; narrowly sympatric with it on both N Borneo and Sumatra. Specimens from each island differ slightly in pelage tone and craniodental dimensions and proportions, but the sample from Sumatra ( atchinus) is small and significance of the differences between it and the much larger series from Sabah requires study of more material from Sumatra (Musser and Newcomb, 1983).
