Here, we sequenced and annotated the complete mitochondrial genome (mitogenome) of (Hemiptera: Pentatomidae). This mitogenome was 15,118 bp long, comprising of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes ( and ) and a large non-coding control region. The mitogenome with an A + T content of 76.0%, presented a positive AT-skew (0.11) and a negative GC-skew (-0.13). Ten PCGs started with a typical ATN codon, two PCGs started with TTG (, ), whereas the remaining one used AAC (). All tRNAs had a typical secondary cloverleaf structure, except for which lacked the dihydrouridine arm. The Bayesian phylogenetic analysis based on mitogenomic data supported a sister relationship of and from the same tribe Nezarini and recovered a phylogeny of Pentatominae: (Menidini + (Strachiini + (Pentatomini + ((Cappaeini + Halyini) + (Eysarcorini + (Nezarini + Carpocori)))))).
在此，我们对（半翅目：蝽科）的完整线粒体基因组（线粒体基因组）进行了测序和注释。该线粒体基因组长度为15,118 bp，由13个蛋白质编码基因（PCGs）、22个转移RNA基因（tRNAs）、2个核糖体RNA基因（和）以及一个大的非编码控制区组成。该线粒体基因组的A + T含量为76.0%，呈现正的AT偏斜（0.11）和负的GC偏斜（-0.13）。10个PCGs以典型的ATN密码子起始，2个PCGs以TTG起始（，），而其余一个使用AAC（）。除了缺少二氢尿苷臂的之外，所有tRNAs都具有典型的二级三叶草结构。基于线粒体基因组数据的贝叶斯系统发育分析支持了来自同一部落Nezarini的和的姐妹关系，并恢复了蝽亚科的系统发育：（Menidini +（Strachiini +（Pentatomini +（（Cappaeini + Halyini） +（Eysarcorini +（Nezarini + Carpocori））））））。
