摘　　要：2014年在黑龙江省横道河子地区(44°48′44″N,129°02′04″E,海拔约740 m)采集到1只鼩鼱(标本编号为CH5)。2015年在内蒙古自治区达赉湖地区(48°37′20″N,117°53′17″E,海拔约720 m)采集2只鼩鼱(标本编号为DE7和DE12)。这些新获标本经鉴定为姬鼩鼱(Sorex minutissimus)。《小鼩鼱(食虫目:鼩鼱科)辽宁省新纪录》文中的标本(080910,090920)经重新鉴定也为姬鼩鼱。利用mt DNA的Cyt b基因全序列构建系统进化树,结果揭示,小鼩鼱聚为一支,姬鼩鼱聚为另一支,新获标本(CH5、DE7、DE12)和待厘定标本(080910、090920)都聚在姬鼩鼱一支,进一步支持形态学鉴定结果。2015年采集的姬鼩鼱为内蒙古自治区新纪录,而《小鼩鼱(食虫目:鼩鼱科)辽宁省新纪录》文中的小鼩鼱(Sorex minutus)(标本号:080910,090920)更正为辽宁省姬鼩鼱新纪录。One specimen（CH5） was trapped at Hengdaohezi region（44°48′44″N, 129°02′04″E, altitude 740 m） in 2014 in Heilongjiang Province, China. Two more specimens（DE7, DE12） were trapped in 2015 in Dalai Lake region（48°37′20″N, 117°53′17″E, altitude 720 m） in Inner Mongolia Autonomous, China. The three specimens（CH5, DE7, DE12） were identified as Sorex minutissimus（Table 1 and Fig. 1）. Two specimens（080910, 090920） that was collected in Laoning Province and recognized as Insectivora, Soricidae were corrected as S. minutissimus（Table 1 and Fig. 2） by the phylogenetic tree constructed by the complete sequence of mitochondrial cytochrome b gene. The specimens（CH5, DE7, DE12） and specimens（080910, 090920） were gathered together in the branch of S. minutissimus（Fig. 3）. The result supported morphology results further in this study. The specimens（DE7, DE12） of S. minutissimus are considered as a new record in the mammalian fauna of Inner Mongolia Autonomous. The specimens（080910, 090920） are corrected as the new record of S. minutissimus to the mammalian fauna of Liaoning Province, too.
