Complete mitochondrial genome of Polyphylla gracilicornis (Coleoptera：Scarabaeoidea)

Polyphylla gracilicornis is one of the important underground pest species that damage agricultural and forestry plants and often requires chemical control during outbreak. Here, we determined the complete mitochondrial genome sequence of P. gracilicornis (GenBank accession no. MW143080) using Illumina NovaSe Sequencing System with a read length of 150 bp. The complete mitogenome consists of a 16,793 bp circular DNA molecule and the overall base composition was 36.97% A, 31.95% T, 10.41% G and 20.67% C. The full mitochondrial genome contains 38 sequence elements: 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a putative control region (CR). All protein-coding genes of P. gracilicornis have the typical ATN (Met) start codons and typical TAN stop codons. Phylogenetic analysis revealed that P. gracilicornis clustered into a clade with homologous species with high bootstrap support.
