A new record of Anourosorex squamipes in Jiangxi Province with a discussion of its geographical range

We collected three male individuals of Chinese mole shrew (Anourosorex squamipes) from Suichuan County, Jiangxi Province,in our field survey in August 2013,and this is the first time this species has been recorded in Jiangxi Province. The external and skull measurements are as follows:body weight 15.8 - 21.6 g,total length 107.0 -125.0 mm,head and body length 95.0 - 112.0 mm,tail length 12.0 -13.0 mm,front foot length 10.5 -11.1mm, hind foot length 13.5 - 15.7 mm,greatest length of skull 24.74 - 25.83 mm,median palatal length 11.27 -11.98 mm,basion-staphylion 10.82 -11.33 mm,postpalatal depth 5.51 -5.65 mm,rostrum length 3.55 - 3.70 mm,interorbital breadth 6.28 - 6.62 mm,greatest breath of braincase 13. 53 - 13.96 mm,length of upper toothrow 10.97 -11.94 mm,mandibular length 16.13 -17.63 mm,oral height of the vertical ramus 6.87 -7.17 mm. The dental formula is 1.2.1.3/ 1.1.1.3=26. This new record of A. squamipes in Jiangxi Province greatly expands the eastern line of the historical distribution of this species in mainland China,the authors imply that the historical distribution of A. squamipes was greatly underestimated due to limitations of field survey data,and A. squamipes may occur in middle elevation areas in southern mainland China.
