Mus (Coelomys) pahari Thomas 1916

Mus (Coelomys) pahari Thomas 1916 , J. Bombay Nat. Hist. Soc., 24: 414.

Type Locality: India, Sikkim, Batasia, 6000 ft (1830 m).

Vernacular Names: Indochinese Shrewlike Mouse.

Synonyms: Mus (Coelomys) gairdneri (Kloss 1920) ; Mus (Coelomys) jacksoniae (Thomas 1921) ; Mus (Coelomys) meator (G. M. Allen 1927) ; Mus (Coelomys) mocchauensis Dao 1978 .

Distribution: From NE India (Sikkim, West Bengal, Arunachal Pradesh, Assam, Nagaland, Meghalaya, and Mizoram; Agrawal, 2000) and Bhutan through N Burma, S China ( SE Xizang, Yunnan, S Sichuan, Guizhou, and Guangxi; Wang [2003], Zhang et al. [1997], Wu et al. [1996], FMNH 40710), Thailand (J. T. Marshall, Jr., 1977 a; Robinson et al., 1996), Cardamom Mtns of SW Cambodia (A. Smith, in litt.), Laos, and C and N Vietnam ( Dang et al., 1994; specimens in AMNH and IEBR); see J. T. Marshall, Jr. (1977 a) and Corbet and Hill (1992).

Conservation: IUCN – Lower Risk (lc).

Discussion: Subgenus Coelomys . Dao (1978) described mocchauensis as a subspecies of M. pahari . Chromosomal features of Thai samples reported by Gropp et al. (1973); 2n = FN = 48. Relationships within Mus assessed by sequences of the Sry gene ( Graur, 1994); forms clade basal to species in subgenera Nannomys , Pyromys , and Mus according to study of Sry and five other genes ( Lundrigan et al., 2002) and DNA/DNA hybridization experiments ( Chevret et al., 2003). The close association between M. pahari and M. crociduroides and placement in subgenus Coelomys is supported by analysis of mitochondrial 12S rRNA sequences ( Chevret et al., 2003). Those two species and M. mayori belong in a clade as indicated by analyses of morphological traits ( Chevret et al., 2003; J. T. Marshall, Jr., 1977 b). Sequences of APRT gene used to illuminate substitution rate variation among M. pahari , M. spicilegus , and other muroids ( Fieldhouse et al., 1997). Ecology of population in S Yunnan and comparisons with species of Rattus , Bandicota , Maxomys , Leopoldamys , and Niviventer from the same forests reported by Wu et al. (1996).

Documented in middle and late Pleistocene cave sediments from the Sichuan-Guizhou region ( Zheng, 1993) and Guangxi ( Chen et al., 2002) of S China. Isolated molars from cave deposits in Thailand indicates the species was present in that region since the middle Pleistocene ( Chaimanee, 1998) .
