The complete mitochondrial genome (mitogenome) of Robinson, 1986 (Lepidoptera: Tineidae), comprises 15,027 base pairs (bp) and contains a typical set of genes (13 protein-coding genes [PCGs], 2 rRNA genes, and 22 tRNA genes), and 1 non-coding region. The genome has an arrangement, --, instead of typical - - at the and junction. This arrangement is unique in lepidopteran mitogenomes. Unlike most lepidopteran insects, which have CGA as the start codon for the gene sequence, had a typical ATT codon. The A + T-rich region was unusually short, with only 199 bp. Phylogenetic analyses with concatenated sequences of the 13 PCGs and two rRNA genes using the Bayesian inference method placed in Tineidae as a sister to the cofamilial species, , with high nodal support (Bayesian posterior probability [BPP] = 0.99), presenting the superfamily Tineoidea in a monophyletic group with a BPP of 0.99. Gracillarioidea, represented by three species of Gracillariidae, formed a monophyletic group with the highest BPP, but the in Yponomeutoidea was unusually grouped together with the Gracillarioidea with the highest nodal support. As more mitogenome sequences are available, further analysis to infer the relationships among superfamilies of Lepidoptera might be possible.
罗宾逊麦蛾（1986年）（鳞翅目：麦蛾科）的完整线粒体基因组（线粒体基因组）由15,027个碱基对（bp）组成，包含一组典型的基因（13个蛋白质编码基因[PCGs]、2个rRNA基因和22个tRNA基因）以及1个非编码区。该基因组在和连接处的排列为--，而非典型的--。这种排列在鳞翅目线粒体基因组中是独特的。与大多数鳞翅目昆虫不同，大多数鳞翅目昆虫的基因序列起始密码子为CGA，而罗宾逊麦蛾具有典型的ATT密码子。富含A+T的区域异常短，只有199 bp。使用贝叶斯推断方法对13个PCGs和两个rRNA基因的串联序列进行系统发育分析，结果将罗宾逊麦蛾置于麦蛾科中，作为同科物种的姐妹种，具有较高的节点支持率（贝叶斯后验概率[BPP]=0.99），表明麦蛾总科在一个单系类群中，BPP为0.99。以潜蛾科的三个物种为代表的潜蛾总科形成了一个BPP最高的单系类群，但巢蛾总科中的罗宾逊麦蛾异常地与潜蛾总科聚在一起，具有最高的节点支持率。随着更多线粒体基因组序列的可得，进一步分析以推断鳞翅目总科之间的关系可能是可行的。
