The superfamily Yponomeutoidea, one of the early-derived groups in the order Lepidoptera, consists of 11 families. However, mitochondrial genome (mitogenome) sequences, popularly used for phylogeny and evolutionary tracing, are available for only seven species across six genera and five families. Thus, a larger variety of mitogenome sequences in Yponomeutoidea are required to improve our understanding of lepidopteran phylogeny and genomic evolution. In this study, we present the complete mitogenome of (Fitch, 1856), the first species in the family Attevidae (superfamily Yponomeutoidea, order Lepidoptera) to be sequenced. The complete mitogenome comprises 16,329 bp and contains a typical set of genes and one non-coding region. Within Yponomeutoidea, the mitogenome of has a unique -- arrangement at the A + T-rich region and junction and - arrangement at the and junction. Twelve of the 13 protein-coding genes (PCGs) of have a typical ATN starting codon, whereas has the atypical CGA codon, which is frequently found in the starting region of lepidopteran . Phylogenetic analyses, based on the concatenated sequences of 13 PCGs and two rRNA genes, using the Maximum Likelihood method, revealed a sister relationship between Attevidae and Praydidae with moderately low nodal support (bootstrap support = 64%).
巢蛾总科是鳞翅目中早期分化的类群之一,由11个科组成。然而,常用于系统发育和进化追踪的线粒体基因组(mitogenome)序列,在六个属和五个科中仅有七个物种有相关数据。因此,需要更多种类的巢蛾总科线粒体基因组序列,以增进我们对鳞翅目系统发育和基因组进化的理解。在本研究中,我们公布了(菲奇,1856)的完整线粒体基因组,它是巢蛾科(巢蛾总科,鳞翅目)中首个被测序的物种。完整的线粒体基因组由16,329个碱基对组成,包含一组典型的基因和一个非编码区。在巢蛾总科内,该物种的线粒体基因组在富含A+T的区域和连接处有独特的排列方式,在和连接处有排列方式。该物种13个蛋白质编码基因(PCGs)中的12个具有典型的ATN起始密码子,而具有非典型的CGA密码子,这在鳞翅目昆虫的起始区域中经常出现。基于13个PCG和两个rRNA基因的串联序列,采用最大似然法进行的系统发育分析表明,巢蛾科和Praydidae之间存在姐妹关系,节点支持率中等偏低(自展支持率=64%)。
