A giant water bug (Hemiptera: Belostomatidae) is a large, predatory, and nocturnal hemipteran insect, which has been considered threatened and thus enrolled as an endangered species in South Korea and Japan. Here, we characterized the complete mitochondrial genome of , which has a circular form with 19,295 bp in length, which is the longest when compared to those of the 111 hemipteran species reported so far. Its longest genome size is due to the extremely extended CR (4686 bp), which is much longer than those of China and Japan. It consisted of a total of 37 genes (13 PCGs, 22 tRNA genes, and two rRNA genes) and one control region (CR). The genome composition and gene order were identical to those previously reported from the same species of China and Japan with over 99.7% sequence similarities except for CR and . The nucleotide composition was highly A + T biased, accounting for 71% of the whole mitochondrial genome, as in other species of Nepoidea. Based on the aa sequences of 13 PCGs, we reconstructed a maximum likelihood tree, which indicated that the three mitochondrial genomes of from South Korea, China, and Japan are grouped, and also , Belostomatidae, Nepoidea, Nepomorpha, Heteroptra are strong monophyletic groups, respectively.
大田鳖（半翅目：负子蝽科）是一种大型、肉食性的夜行半翅目昆虫，在韩国和日本被视为受威胁物种，因此被列为濒危物种。在此，我们对[物种名称未给出]的完整线粒体基因组进行了特征分析，其呈环状，长度为19295 bp，与迄今报道的111种半翅目物种相比是最长的。其基因组最长是由于CR（控制区）极度延长（4686 bp），比中国和日本的同类物种长得多。它总共由37个基因组成（13个蛋白质编码基因、22个tRNA基因和两个rRNA基因）以及一个控制区（CR）。除CR和[此处可能缺失信息]外，基因组组成和基因顺序与先前报道的来自中国和日本的同物种相同，序列相似度超过99.7%。核苷酸组成高度偏向A + T，占整个线粒体基因组的71%，与其他负子蝽总科物种情况相同。基于13个蛋白质编码基因的氨基酸序列，我们构建了一个最大似然树，结果表明来自韩国、中国和日本的[物种名称未给出]的三个线粒体基因组聚为一类，并且负子蝽科、负子蝽总科、异翅亚目、半翅目也分别形成了强大的单系类群。
