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。
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.
