Characterization of the complete mitochondrial genome and phylogenetic analysis of Epiverta chelonia (Coleoptera: Coccinellidae)

Abstract

Epiverta chelonia (Mader 1933; Coleoptera: Coccinellidae) is an important economically and scientifically valuable insect. In this study, the first complete mitochondrial genome of E. chelonia was sequenced and characterized using next-generation sequencing techniques. The circular mitogenome of E. chelonia consists of 17,347 bp including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region (D-loop). The base composition was AT-biased (75.77%). Bayesian Inference and Maximum likelihood phylogenetic trees strongly supported the monophyly of Coccinellinae. Also, E. chelonia was supported as the sister group of Subcoccinella vigintiquatuorpunctata, within Epilachninae. Thus, the E. chelonia mitochondrial genome will be a fundamental resource for understanding the molecular phylogenetic relationships of the species-rich family Coccinellidae of Coleoptera.
