中国兽类一新纪录:尼泊尔长尾鼩鼱
First record of Nepalese brown-toothed shrew(Episoriculus soluensis)in China
摘要
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 solu-ensis.The parietal bone of the skull protrudes.The specimens have four upper unicuspids,the posterior cusps of the up-per incisor are similar in height to the first upper unicuspid,and the cusps are light brown.These characteristics are con-sistent with those of E.soluensis,as is a phylogenetic analysis of Cyt b sequences based on data for the species in Gen-Bank.The K2P distance between them is merely 3.0％.Thus,morphological and molecular analyses confirm the col-lected specimens constitute a new species record for the mammalian fauna of China.关键词
