摘要/Abstract

摘要： 2023年8月在西藏自治区亚东县上亚东乡附近和定结县陈塘镇附近采集到4只鼩鼱。该种背毛深棕色，腹毛浅黄棕色，背腹界线不明显，尾上下两色；头骨顶骨较为隆突，上单尖齿4枚，上颌门齿后齿尖与第一上单尖齿高度相近，齿尖呈浅棕色，符合尼泊尔长尾鼩鼱(Episoriculus soluensis)的鉴定特征。4项外形和9项头骨测量数据与尼泊尔长尾鼩鼱原始测量数据基本一致。在基于Cyt b构建的系统树中与从GenBank中下载的尼泊尔长尾鼩鼱聚为一枝，两者间遗传距离为3.0%。基于形态和分子鉴定，确定这批标本是尼泊尔长尾鼩鼱，为中国兽类新纪录。

Abstract: In August 2023, four specimens of shrew were collected from the Upper Yadong Township, Yatung, and Chen tang Town, Tingkye, Xizang Autonomous Region. Dorsally, the hair of this species is dark brown, the ventral hair light yellowish brown, the dorsoventral line is indistinct, and the tail two colors divided above and below. The four external measurements and nine skull measurements are basically consistent with the original measurements of Episoriculus soluensis. The parietal bone of the skull protrudes. The specimens have four upper unicuspids, the posterior cusps of the upper incisor are similar in height to the first upper unicuspid, and the cusps are light brown. These characteristics are consistent with those of E. soluensis, as is a phylogenetic analysis of Cyt b sequences based on data for the species in GenBank. The K2P distance between them is merely 3.0%. Thus, morphological and molecular analyses confirm the collected specimens constitute a new species record for the mammalian fauna of China.
