The Trichoptera (caddisflies) is a holometabolous insect order with 14,300 described species forming the second most species-rich monophyletic group of animals in freshwater. Hitherto, there is no mitochondrial genome reported of this order. Herein, we describe the complete mitochondrial (mt) genome of a caddisfly species, Eubasilissa regina (McLachlan, 1871). A phylogenomic analysis was carried out based on the mt genomic sequences of 13 mt protein coding genes (PCGs) and two rRNA genes of 24 species belonging to eight holometabolous orders. Both maximum likelihood and Bayesian inference analyses highly support the sister relationship between Trichoptera and Lepidoptera.
蜉蝣目(蜉蝣)是一个完全变态的昆虫目,有 14300 种已描述的物种,是淡水动物中第二大具有单系性的物种丰富类群。迄今为止,还没有关于这个目的线粒体基因组的报道。本文描述了一种蜉蝣物种,Eubasilissa regina(McLachlan,1871)的完整线粒体(mt)基因组。基于 13 种 mt 蛋白编码基因(PCGs)和 24 种属于 8 个完全变态目(Lepidoptera)的 2 种 rRNA 基因的 mt 基因组序列进行了系统基因组分析。最大似然和贝叶斯推断分析都高度支持蜉蝣目和鳞翅目之间的姐妹关系。
