目前对藏鼩鼱（Sorex thibetanus）和甘肃鼩鼱（Sorex cansulus）的分布范围和生物学资料了解较少。2017年，在云南省西北部的高山区域采集了48号鼩鼱属（Sorex）动物标本。用形态学和基于Cyt b基因的分子系统学对采集标本进行了物种鉴定。结果显示来自4个地点的27号标本形态上与藏鼩鼱相符，来自2个地点的21号标本与甘肃鼩鼱相似，但存在一定差异。基于Kimura-2-parameter的遗传距离显示，藏鼩鼱组内遗传距离为0.46%，甘肃鼩鼱组内遗传距离为0.42%。它们与其它鼩鼱属物种的组间遗传距离分别为10.76%~17.04%和6.59%~14.52%。最大似然（Maximum likelihood）树结果显示，来自云南省西北部的两种鼩鼱动物分别与藏鼩鼱（BS=71%）和甘肃鼩鼱（BS=100%）构成单系。上述结果支持这两种鼩鼱属动物分别为藏鼩鼱和甘肃鼩鼱，均为云南省兽类新纪录。

Tibetan shrew(Sorex thibetanus) and Gansu shrew(Sorex cansulus) are two poorly known species of the genus Sorex. In 2017, 48 specimens of Sorex were collected in alpine areas of north-west Yunnan. The morphological characteristics and measurements of these specimens were compared with previous specimen records, and their phylogenetic relationships with other Sorex species were assessed based on Cyt b gene. Results show that 27 specimens from 4 sites are morphologically similar to S. thibetanus, while other 21 specimens from 2 sites are morphologically similar to S. cansulus, although with considerable differences. The intraspecific Kimura-2-parameter distance based on Cyt b was 0.46% for S. thibetanus and 0.42% for S. cansulus, while the distances between these two species to other Sorex species were 10.76%-17.04% and 6.59%-14.52%, respectively. Maximum likelihood phylogenetic analyses support the two species are monophyletic to S. thibetanus(BS=71%) and S. cansulus (BS=100%), which both are new mammal records in Yunnan Province.
