The complete mitogenome of (GenBank accession number MT611524) is 15,511 bp in length, and harbors 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and an A + T-rich region. The overall base composition is A (40.04%), C (10.64%), G (7.62%), and T (41.70%), showing AT-rich feature (81.74%). ATG, ATT, CGA were initiation codons and TAA and T were termination codons. All the 22 tRNAs displayed a common cloverleaf secondary structure, except for which lacked the dihydrouracil (DHU) arm. Phylogenetic tree based on 13 PCGs showed that has a close phylogenetic relationship with and and belongs to Gracillariidae.
（GenBank登录号MT611524）的完整线粒体基因组长度为15511 bp，包含13个蛋白质编码基因（PCGs）、22个转运RNA基因（tRNAs）、两个核糖体RNA基因和一个富含A+T的区域。总体碱基组成为A（40.04%）、C（10.64%）、G（7.62%）和T（41.70%），呈现出富含AT的特征（81.74%）。ATG、ATT、CGA为起始密码子，TAA和T为终止密码子。除了缺少二氢尿嘧啶（DHU）臂的 外，所有22个tRNAs都呈现出常见的三叶草二级结构。基于13个PCGs构建的系统发育树表明， 与 和 具有密切的系统发育关系，属于细蛾科。
