The complete mitochondrial genome of Euproctis similis (Lepidoptera: Noctuoidea: Erebidae) and phylogenetic analysis

The mitochondrial genome (mitogenome) can provide information for phylogenetic analyses and evolutionary biology. We sequenced, annotated, and characterized the mitogenome of Euproctis similis. The complete mitogenome is 15,437bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and a control region (A+T-rich region). The A+T content in the mitogenome was 80.16%. All PCGs use standard ATN as a start codon, with the exception of cytochrome c coxidase 1 (cox1) with CGA. A gene rearrangement (trnM) was found. All transfer RNA (tRNA) genes have a typical clover-leaf structure except for trnS1 (AGN). Phylogenetic analysis was performed using Bayesian Inference and Maximum Likelihood based on the amino acid and nucleotide sequences of 13 mitochondrial PCGs. The well-supported phylogenetic relationships can be generally described as: Notodontidae+(Erebidae+(Nolidae+(Euteliidae+Noctuidae))). The tree support that E. similis shares a close ancestry with Erebidae insects. Our results indicate that Erebidae is a sister group to the other families (Euteliidae, Nolidae, and Noctuidae).
