The complete mitochondrial genome of Lethe albolineata is a circular molecule of 15,248 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (LrRNA and SrRNA), and a non-coding AT-rich region. All PCGs use the standard ATN start codon, except for COI, which begins with CGA. Eight PCGs employ complete stop codon (TAA), whereas the others use a single T or TA acting as an incomplete stop codon. The AT-rich region is 413 bp in length, which contains a conserved motif common to the other lepidopteran species. Two tRNA-like pseudo-genes are found in the mitochondrial genome of L. albolineata. The phylogenetic analysis shows that L. albolineata exhibits most close relationship with L. dura.
白线黛眼蝶的完整线粒体基因组是一个长度为15248 bp的环状分子，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（LrRNA和SrRNA）以及一个富含AT的非编码区。除了以CGA起始的COI外，所有PCGs均使用标准的ATN起始密码子。8个PCGs使用完整的终止密码子（TAA），而其他的则使用单个T或TA作为不完整的终止密码子。富含AT的区域长度为413 bp，其中包含一个其他鳞翅目物种共有的保守基序。在白线黛眼蝶的线粒体基因组中发现了两个类似tRNA的假基因。系统发育分析表明，白线黛眼蝶与褐黛眼蝶的关系最为密切。
