The first mitochondrial genomes for Pyralinae (Pyralidae) and Glaphyriinae (Crambidae), with phylogenetic implications of Pyraloidea.

Abstract

In the present study, we report five complete and one nearly complete mitochondrial genomes of the Pyraloidea including the first representatives from the Pyralinae (Pyralidae) and Glaphyriinae (Crambidae). We also conduct a comparative analysis of mitogenomic features of this group. Our results show that Pyraloidea mitogenomes evolved under a common trend found in lepidopteran mitogenomes and share several typical genomic characters. The extra conserved blocks are identified in the Pyraloidea control region, and diverse missing codons formed another unique trait within Pyraloidea mitogenome. Furthermore, we reconstruct the mitogenomic phylogeny of Pyraloidea and confirm the phylogenetic position of Pyralinae and Glaphyriinae within the Pyraloidea using BI and ML method based on multiple mitochondrial datasets.
