Mag. Nat. Hist., ser. 8, 20: 198 . Type Locality: Taiwan , Mt Arizan, 8000 ft ( 2440 m ). Vernacular Names: Soft-furred Taiwan Niviventer . Distribution: Endemic to highlands of Taiwan , 2000-3000 m (H.- T . Yu, 1994; M.-J. Yu, 1996). Conservation: IUCN – Lower Risk (nt). Discussion: Historically listed as a species ( Ellerman, 1941 ), a subspecies of N. niviventer ( Ellerman, 1961 ; Ellerman and Morrison-Scott, 1951 ; Wang and Zheng, 1981 ), or included in N. confucianus ( Musser, 1981 b ; Corbet and Hill, 1992 ). Niviventer culturatus is a distinctive insular form that in morphology superficially resembles mainland N. confucianus , but differs sufficiently that it should be treated as a species, as revealed by multivariate analysis of morphometric traits by Musser and Lunde (ms), which also clusters N. culturatus with the Javan N. lepturus , Chinese N. andersoni and N. excelsior , and Burmese N. brahma , but not with N. confucianus . Analyses of mitochondrial cytochrome b sequences also highlights the specific integrity of N. culturatus but places it with N. confucianus , N. coninga , and N. tenaster in a monophyletic clade (J. L. Patton, in litt., 2000; N. langbianis and N. fulvescens were the only other Niviventer sampled). Chromosomal data documented by H.- T . Yu et al. (1996) and compared with karyotype of N. coninga (see account of that species). Ecology, distribution and abundance along an elevational gradient, and genetic population structure documented by H.- T . Yu (1993, 1994, 1995); microhabitat use reported by Adler (1996) .
