| 中文摘要: |
| 2016年12月，在湖北省兴山县采集到1只食虫类标本。其体型较小（头体长 75.00 mm），通体呈棕褐色，尾较长（82.00 mm），眼细小。头骨扁平，较为坚固，齿尖具有浅红棕色色斑。通过测定其线粒体Cyt b基因序列，并结合缺齿鼩属6个物种的同源区序列，构建其系统发生关系，发现该标本与基因库中霍氏缺齿鼩（Chodsigoa hoffmanni）序列聚为具较高支持度的一支。综合形态学与系统发育学证据，将该标本鉴定为霍氏缺齿鼩。此次发现是湖北省境内该物种的首次记录，也是其在我国云南省及越南分布区外的又一发现，拓展了对该物种在我国分布范围的认识。 |
| 英文摘要: |
| A shrew specimen which has not been recorded in Hubei Province before was collected Xingshan county, Hubei on December 2016. Morphologically it was grey and brown, with a head and body length of 75.00 mm, a relatively long tail (82.00 mm) and tiny eyes. Its cranium was flat and fairly solid and its teeth tips had light reddish-brown spots. Its species identity was established phylogenetically, based on the mitochondrial cytochrome b gene sequence, and combined with the homologous sequences of six other Chodsigoa species obtained from NCBI database. These individuals clustered with C. hoffmanni and combined into a monophyletic clade in the phylogenetic tree, with a closer genetic distance to C. hoffmanni than to any other species. On the basis of this morphological and phylogenetic evidence, this specimen was confirmed as a Hoffmann’s long-tailed shrew (C. hoffmanni). This species was also recorded formerly in Yunnan province, China and Vietnam. Our finding extended the previously known geographical range of this shrew species. |
