The species diversity within the genus Uropsilus were underestimated: 10 species among the genus Uropsilus have been proposed. In this study, the complete mitochondrial genome of U. gracilis, with the topotype, was determined. It is 16,536 bp in length, comprising of 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and 1 control region. The composition and arrangement of its genes are similar to most other mammals. The total base composition of the mitogenome is A, 33.4%; T, 30.3%; C, 22.7% and G, 13.6%, with a rich content of A+T pattern. We performed the similarity comparison based on 13 PCGs of three species of Asiatic shrew-like mole, U. gracilis, U. sp. 1 and U. soricipes. Pairwise sequence alignment showed that similarity data of U. gracilis versus U. sorcipes are significantly higher than those of U. gracilis versus U. sp.1. This pointed toward a cryptic species (U. sp.1) from Jiajin Mountains rather than U. gracilis.
已提出长尾鼩属中有10个物种。在本研究中，测定了指名亚种细尾长尾鼩的完整线粒体基因组。其长度为16,536 bp，由13个蛋白质编码基因（PCGs）、2个rRNA基因、22个tRNA基因和1个控制区组成。其基因的组成和排列与大多数其他哺乳动物相似。线粒体基因组的总碱基组成为A，33.4%；T，30.3%；C，22.7%；G，13.6%，具有丰富的A+T模式。我们基于三种亚洲鼩鼹（细尾长尾鼩、长尾鼩1号物种和中华长尾鼩）的13个PCGs进行了相似性比较。成对序列比对显示，细尾长尾鼩与中华长尾鼩的相似性数据显著高于细尾长尾鼩与长尾鼩1号物种的相似性数据。这表明来自夹金山脉的是一个隐存物种（长尾鼩1号物种）而非细尾长尾鼩。
