is a small genus in Acroneuriinae, which was established by Chu but was treated as a synonym for a long time until Uchida and Harper recognized as a valid genus. This genus includes 15 species in the world now, including six species from China. Here, we sequenced and annotated the mitochondrial genome of sp. under the next-generation sequence technology, the first representative of Genus . The complete mitochondrial genome of sp. is 15,796 bp in length with an A + T content of 68.3% showed a positive AT-skew (0.037) and a negative GC-skew (-0.262). The gene order and organization of the mitochondrial genome is consistent with other stoneflies. The control region had the highest A + T content. Eleven PCGs started with the typical codon (ATN), the remaining PCGs started with TTG (ND1and ND5). All PCGs terminated with TAA/TAG, except COII and ND5 used single T. The phylogenetic tree by maximum likelihood (ML) and Bayesian (BI) methods supported that sp. was the sister group to .
是石蝇科中的一个小属，由Chu建立，但在很长一段时间内被视为同义词，直到Uchida和Harper将其确认为一个有效属。该属目前世界上有15个物种，其中6种来自中国。在此，我们在新一代测序技术下对该属的 种的线粒体基因组进行了测序和注释，它是该属的首个代表物种。该种的完整线粒体基因组长度为15,796 bp，A+T含量为68.3%，呈现正的AT偏斜（0.037）和负的GC偏斜（-0.262）。线粒体基因组的基因顺序和组织与其他石蝇一致。控制区的A+T含量最高。11个蛋白质编码基因（PCGs）以典型密码子（ATN）起始，其余PCGs以TTG起始（ND1和ND5）。除COII和ND5使用单个T外，所有PCGs均以TAA/TAG终止。通过最大似然法（ML）和贝叶斯法（BI）构建的系统发育树支持该种是 的姐妹群。
