Characterization of the complete mitochondrial genome of Pentatoma semiannulata (Hemiptera: Pentatomidae)

The Pentatoma semiannulata is an important fruit pest in Chinese agricultural system. In current study, the complete mitochondrial genome of P. semiannulata is determined. This mitogenome is 15,515 bp in size and comprises of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. Gene order is identical to that of the putative ancestral arrangement of insects. All protein-coding genes initiate with ATN, except for ATP8, COX1 and NAD1 use GTG or TTG as the start codon, and terminate with TAA with the exception for COX2 which uses a single T residue as the stop codon. All tRNAs, ranging from 62 to 72 bp, have the clover-leaf structure except for tRNA(Ser(AGN)). The monophyly of Pentatomidae is highly supported by the phylogenetic tree and P. semiannulata is very close to other herbivorous species of the remaining Pentatomidae species.
