The family Apataniidae consists of two subfamilies, Apataniinae and Moropsychinae. Currently, there are 204 valid species of Apataniidae, which are widely distributed throughout the northern hemisphere. The larvae typically inhabit cold-water environments, and they serve as biological indicators for monitoring the health of freshwater ecosystems. The phylogenetic relationships within Apataniidae are not fully understood. Moreover, the available molecular data of Apataniidae are still limited. Herein, we provided the mitochondrial genomes of eight apataniid species and compared them with the published mitochondrial genomes of Apataniidae. The nine newly obtained sequences ranged from 15,070 bp to 16,737 bp in length. The results of the nonsynonymous with synonymous substitution rates displayed that had the highest evolutionary rate, while exhibited the lowest. The may be an effective molecular marker for the classification of the Apataniidae. Based on the published mitogenomes, we constructed a phylogenetic tree for Limnephiloidea and conducted a preliminary analysis of its advanced phylogeny. The ML and BI analyses recover the monophyly of Apataniidae and Limnephilidae. Except for PCG, BI tree based on other matrices consistently showed the topology: ( + ( + ( + ))). The taxonomic status of and were also preliminarily explored. The mitochondrial genome of Apataniidae provides critical genomic resources for understanding the phylogenetic relationships of Apataniidae.
阿帕塔尼科昆虫科由两个亚科组成，即阿帕塔尼亚科和莫罗普西尼亚科。目前，阿帕塔尼科昆虫科有204个有效物种，广泛分布于北半球。其幼虫通常栖息在冷水环境中，可作为监测淡水生态系统健康状况的生物指标。阿帕塔尼科昆虫科内部的系统发育关系尚未完全明晰。此外，阿帕塔尼科昆虫科现有的分子数据仍然有限。在此，我们提供了8种阿帕塔尼科昆虫的线粒体基因组，并将它们与已发表的阿帕塔尼科昆虫线粒体基因组进行了比较。新获得的9条序列长度在15,070 bp至16,737 bp之间。非同义替换率与同义替换率的结果显示，[此处原文缺失具体物种名称]进化速率最高，而[此处原文缺失具体物种名称]进化速率最低。[此处原文缺失具体物种名称]可能是阿帕塔尼科昆虫科分类的有效分子标记。基于已发表的线粒体基因组，我们构建了沼石蛾总科的系统发育树，并对其高级系统发育进行了初步分析。最大似然法（ML）和贝叶斯推断（BI）分析均支持阿帕塔尼科昆虫科和沼石蛾科的单系性。除了蛋白质编码基因（PCG）外，基于其他矩阵的BI树始终显示出拓扑结构：（[此处原文缺失具体物种名称1] + （[此处原文缺失具体物种名称2] + （[此处原文缺失具体物种名称3] + （[此处原文缺失具体物种名称4] + [此处原文缺失具体物种名称5]））））。还初步探讨了[此处原文缺失具体物种名称6]和[此处原文缺失具体物种名称7]的分类地位。阿帕塔尼科昆虫科的线粒体基因组为理解阿帕塔尼科昆虫科的系统发育关系提供了关键的基因组资源。
