Dinorhynchus dybowskyi (Hemiptera: Pentatomidae: Asopinae) is used as a biological control agent against various insect pests for its predatory. In the present study, the complete mitochondrial genome (mitogenome) of the species was sequenced using the next-generation sequencing technology. The results showed that the mitogenome is 15,952 bp long, including 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and a control region. Furthermore, the gene order and orientation of this mitogenome are identical to those of most heteropterans. There are 21 intergenic spacers (of length 1-28 bp) and 13 overlapping regions (of length 1-23 bp) throughout the genome. The control region is 1,291 bp long. The start codon of the PCGs is ATN, except cox1 (TTG), and stop codon is TAA, except nad1 (TAG). The 22 tRNAs exhibit a typical cloverleaf secondary structure, except trnS1, which lacks a dihydrouridine (DHU) arm and trnV, where the DHU arm forms a simple loop. The analyses based on nucleotide sequences of the 13 PCGs by Bayesian Inference and maximum likelihood methods. The results support the monophyly of five superfamilies Aradoidea, Pentatomoidea, Pyrrhocoroidea, Lygaeoidea, and Coreoidea. Within Pentatomoidea, the relationship observed is as follows: (Plataspidae + Urostylididae) + (Pentatomidae + (Acanthosomatidae + (Cydnidae + (Scutelleridae + (Dinidoridae + Tessaratomidae))))), and D. dybowskyi was placed in Pentatomidae and close to Eurydema gebleri.
