The mitochondrial genome provides valuable data for phylogenetic analysis and evolutionary research. In this study, we sequenced, assembled, and annotated the mitochondrial genome of using the Illumina platform. The genome spanned 16,967 bp and included 13 protein-coding genes (PCGs), two ribosomal RNAs, and 22 transfer RNAs. All PCGs utilized standard ATN start codons and TAN stop codons. The phylogenetic tree based on maximum likelihood and Bayesian inference analyses revealed Clinocardiinae as the sister group to Trachycardiinae, with the estimated divergence time being 44.5 million years ago (MYA) between and . Notably, the gene () exhibited a positive selection signal. Our findings provide valuable insights into the evolutionary history and molecular phylogeny of .
线粒体基因组为系统发育分析和进化研究提供了有价值的数据。在本研究中，我们使用Illumina平台对[物种名称]的线粒体基因组进行了测序、组装和注释。该基因组跨度为16,967 bp，包含13个蛋白质编码基因（PCGs）、两个核糖体RNA和22个转运RNA。所有PCGs均使用标准的ATN起始密码子和TAN终止密码子。基于最大似然法和贝叶斯推断分析构建的系统发育树显示，Clinocardiinae是Trachycardiinae的姐妹群，[物种名称1]和[物种名称2]之间的估计分歧时间为4450万年前（MYA）。值得注意的是，[基因名称]基因（[具体基因名称]）表现出正选择信号。我们的研究结果为[物种名称]的进化历史和分子系统发育提供了有价值的见解。
