大异翅目湿地包含了大部分的鳞翅目物种。然而，广泛的比较和系统发育分析，这组使用完整的线粒体基因组（mitogenome）是有限的，特别是在不断增加的macroheteroceran mitogenomes报告的背景下。在这项研究中，完整的有丝分裂基因组的Epicopeia hainesii被确定为第一个有丝分裂基因组可用的Epicopeiidae物种。整个有丝分裂基因组为环状，长15，395 bp，核苷酸组成高度偏向A + T核苷酸（80.6%）。比较分析表明，大异角类有丝分裂基因组的基因内容和排列一般是保守的，是典型的鳞翅目，但也存在例外。在新测序的有丝分裂基因组中，“ATACTAA”基序位于nadl基因的末端，而不是在鳞翅目中常规观察到的trnS2和nadl基因之间的基因间序列。有趣的是，多个系统发育分析恢复六个macroheteroceran超科Mimallonoidea +（Drepanoidea +（（Draccoidea + Lasiocampoidea）+（Noctuoidea + Geometroidea），提供了支持大规模的转录组学研究，而不是各种基于有丝分裂基因组和多基因的调查。此外，我们的分析一致地将Epicopeiidae作为姐妹群与Geometroidea，首次证明该家庭是更接近Geometroidea比Drepanoidea基于有丝分裂基因组数据。(C)2019 Elsevier B.V.版权所有。
The Macroheterocera Glade contains most of the Lepidoptera species. However, extensive comparative and phylogenetic analyses of this group using complete mitochondrial genomes (mitogenome) are limited particularly in the context of increasing macroheteroceran mitogenomes reported to date. In this study, complete mitogenome of the Epicopeia hainesii is determined as the first Epicopeiidae species with mitogenome available. The whole mitogenome is circular with 15,395 bp long, and is highly biased toward A + T nucleotides (80.6%) in nucleotide composition. Comparative analyses show that gene content and arrangement of macroheteroceran mitogenomes are generally conservative and are typical of Lepidoptera but exceptions exist. In newly sequenced mitogenome, the motif "ATACTAA" is putatively located at the end of gene nadl, rather than in intergenic sequences between trnS2 and nadl genes routinely observed in Lepidoptera. Interestingly, multiple phylogenetic analyses recover the six macroheteroceran superfamilies as Mimallonoidea + (Drepanoidea + ((Bombycoidea + Lasiocampoidea) + (Noctuoidea + Geometroidea))), providing supports for a large-scale transcriptomic study rather than various mitogenome-and multiple-gene-based investigations. In addition, our analyses consistently place the Epicopeiidae as sister group with Geometroidea, firstly demonstrating that this family is closer with Geometroidea than Drepanoidea based on mitogenome data.
