Complete mitochondrial genome of Hepialus gonggaensis (Lepidoptera: Hepialidae), the host insect of Ophiocordyceps sinensis

Abstract

The complete mitochondrial genome sequence of Hepialus gonggaensis was sequenced for the first time. The complete mtDNA sequence was 15,940 bp in length and contained 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and an AT-rich region, the gene composition and the arrangement of which were identical to other insects of Hepialidae. The overall base composition of the heavy strand was 41.14% A, 40.24% T, 11.17% C, and 7.45% G, with an AT content of 81.37%. The necleotide sequence data of 13 protein-coding genes of H. gonggaensis and other 10 Lepidoptera species were used for constructing the phylogenetic tree. It revealed that H. gonggaensis and other four Hepialidae species were clustered to a clade with high bootstraps values.
