Determining the complete mitochondrial genome of <i>Tethea albicostata</i> (Lepidoptera: Drepanidae) and phylogenetic analysis

<i>Tethea albicostata</i> is a widely distributed insect species in northern and central China. To date, few studies have been conducted on this species, with the exception of morphological taxonomy studies. Here, we report the complete mitochondrial genome of <i>T. albicostata</i> collected in China. The circular-mapping mitogenome is 15,308 bp in length, with an overall A + T content of 80.52%, encoding 2 ribosomal RNA genes, 22 transfer RNA genes, and 13 protein-coding genes. The gene arrangement and components of <i>T. albicostata</i> are identical to those of most other Lepidopteran insects. Phylogenetic analysis based on mitogenomes showed that <i>T. albicostata</i> is grouped with <i>Drepana pallida,</i> which belongs to the same family as Drepanidae. The family Drepanidae formed a separate branch from other families in the phylogenetic tree. This study determined the second mitochondrial genome of the Drepanidae species.白纹带蛾（Tethea albicostata）是广泛分布于中国华北与华中地区的昆虫物种。迄今为止，针对该物种的研究寥寥无几，仅见形态分类学相关报道。本研究报道了采自中国的白纹带蛾完整线粒体基因组。该环状线粒体基因组全长15308 bp，整体A+T碱基含量为80.52%，共编码2个核糖体RNA基因、22个转运RNA基因以及13个蛋白质编码基因。白纹带蛾的基因排布与组成与绝大多数鳞翅目（Lepidoptera）昆虫保持一致。基于线粒体基因组的系统发育分析显示，白纹带蛾与隶属于钩蛾科（Drepanidae）的赭星钩蛾（Drepana pallida）聚为一支。在系统发育树中，钩蛾科（Drepanidae）与其他各科形成独立分支。本研究解析了钩蛾科物种的第二个线粒体基因组。
