云南兽类鼩鼱科一新纪录——台湾灰麝鼩

于2006年10月及2015年8月在中国云南省采集到台湾灰麝鼩(Crocidura tanakae Kuroda,1938)3号成体标本。1号雄性与1号雌性的标本来自屏边县大围山自然保护区(22°53′59″N,103°41′23″E,2 088 m),另1号雌性标本采自富宁县里达镇半边箐(23°28′11"N,105°35′59″E,1 442 m)。其尾毛长而稀疏,尾长变异大,后足宽大,后足足底和掌外侧垫突出、聚集且呈圆形,这些特征与模式产地的标本吻合。其线粒体Cyt b与地模标本的遗传距离为1.6%。采集地生境为原生林与次生林交界处和落叶季雨林。

First Records of Taiwanese Gray Shrew (Crocidura tanakae) in Yunnan Province, China

We collected three adult samples from Daweishan Natural Reserve, Pingbian (22° 53'' 59"N, 103° 41'' 23"E, 2 088 m above sea level) and Banbianqing, Funing (23° 28'' 11"N, 105° 35'' 59"E, 1442 m above sea level). We compared the morphological measurement of our samples with topotype specimen (Table 1, Fig. 1 and 2), and established the phylogenetic relationship using Cyt b sequences (Fig. 3). The results showed that the shape of tail and hind feet was similar with topotype specimens. The P-distance of Cyt b between them was only 1.6%. We confirmed that these three samples belong to Taiwanese Gray Shrew (Crocidura tanakae), which were the first record in Yunnan province. The habitat of collection was the junction of primary and secondary forest and deciduous monsoon forest.
