The Sikkim mountain vole is a small rodent with dark brown upper fur, dark grey underparts and a strip of ochre-brown between them. The upper surfaces of the feet are brownish-white and the tail is bicoloured, brown above and white below. Head and body measure 97 to 119mm and the tail 30 to 52mm (Wikipedia, general species account).
Its range extends from Bhutan, West Bengal and Sikkim through western, central and eastern Nepal at altitudes above 2,500m, and it is also present in southern Tibet between 2,100 and 3,700m. It is very similar to the Chinese scrub vole, and the two can be told apart by their teeth. The source opened gives no diet or breeding detail.
