摘要: 东阳江麝鼩和黄山小麝鼩是最近分别依据地理位置相近的两地点采集标本描记的新物种,从形态学和分子生物学方面对这两个麝鼩新物种进行比较后,发现这两个物种形态描述上多处相似,外形和头骨测量数据多处重叠;线粒体和核基因分析表明两个物种在分子系统树上混杂在一起,没有相互呈现单系;两模式标本Cyt b的遗传距离仅为1.1%;在GenBank中BLAST两个物种模式标本的Cyt b序列相似度达99.56%。因此确定两个物种是同一物种。由于东阳江麝鼩正式发表时间早于黄山小麝鼩,因此,黄山小麝鼩是东阳江麝鼩的次定同物异名。

Abstract: From the morphological and molecular comparison of the two recently published Crocidura species (Crocidura huangshanensis and Crocidura dongyangjiangensis) based on specimens collected from geographically close locations, it is found that the two species are similar in overall description, and the appearance and morphological measurements are overlapped in many skull characteristics.Phylogenetic analysis using mitochondrial and nuclear genes showed the two species were clustered and did not form an independent clade from each other.The uncorrected p-distance of Cyt b holotypes of the two taxon was only 1.1%.In GenBank, the BLAST similarity of Cyt b genes of the two species was 99.56%.Therefore, it is determined that the two taxon should recognized as the same species.Since the publication of Crocidura dongyangjiangensis was earlier than Crocidura huangshanensis, thus we suggest Crocidura huangshanensis Yang, BW Zhang and Li, 2020 as a junior synonym of Crocidura dongyangjiangensis Liu Y, Chen SD, and Liu SY, 2020.
