SPECIES Neodon sikimensis

Author:Horsfield, 1841.
Citation:A Catalogue of the Mammalia in the Museum of the Hon. East-India Company: 145-146 (as corrected by Kaneko and Smeenk, 1996; not Hodgson, 1849, as entrenched in the literature).
Common Name:Sikkim Mountain Vole
Type Locality:India, Sikkim.
Distribution:Himalayas from W to E Nepal (based on FMNH series), through NE India (Sikkim and Darjeeling Dist.) to E Bhutan (Ellerman, 1947a, 1961); also SC and E Xizang (Tibet; Feng et al., 1986; Zhang et al., 1997).
Status:IUCN Lower Risk (lc) as Microtus sikimensis.
Comments:Geographic distribution of N. sikimensis on the E Tibetan Plateau is parapatric with the smaller-bodied and morphologically different N. irene (see account), once included in N. sikimensis. Banded karyotype (2n = 48, FN = 56) described by Mekada et al. (2002), who postulated its derivation from that characterizing N. juldaschi (as Microtus carruthersi). Indian population reviewed by Agrawal (2000); aspects of habitat, individual and age variation reported by Abe (1971) and Gruber (1969).
