Haplodiplatyidae is a recently established earwig family with over 40 species representing a single genus, Hincks, 1955. The morphology of Haplodiplatyidae has been studied in detail, but its molecular characters remain unclear. In this study, two mitogenomes of Ma & Chen, 1991, were sequenced based on two samples from Fujian and Jiangxi provinces, respectively. These represent the first mitogenomes for the family Haplodiplatyidae. The next-generation sequencing method and subsequent automatic assembly obtained two mitogenomes. The two mitogenomes of were generally identical but still exhibit a few sequence differences involving protein-coding genes (PCGs), ribosomal RNA (rRNA) genes, control regions, and intergenic spacers. The typical set of 37 mitochondrial genes was annotated, while many transfer RNA (tRNA) genes were rearranged from their ancestral locations. The calculation of nonsynonymous (Ka) and synonymous (Ks) substitution rates in PCGs indicated the fastest evolving gene in . The phylogenetic analyses supported the basal position of Apachyidae but also recovered several controversial clades.
扁螋科是一个最近建立的蠼螋科，有40多种，代表一个单属（欣克斯，1955年）。扁螋科的形态已经得到了详细研究，但其分子特征仍不清楚。在本研究中，基于分别来自福建和江西的两个样本，对马&陈，1991年的两个线粒体基因组进行了测序。这些代表了扁螋科的首个线粒体基因组。下一代测序方法及随后的自动组装获得了两个线粒体基因组。这两个线粒体基因组总体上是相同的，但在涉及蛋白质编码基因（PCGs）、核糖体RNA（rRNA）基因、控制区和基因间隔区方面仍存在一些序列差异。对37个典型线粒体基因进行了注释，同时许多转运RNA（tRNA）基因从其祖先位置发生了重排。蛋白质编码基因中非同义（Ka）和同义（Ks）替换率的计算表明了[文中未提及具体物种名]中进化最快的基因。系统发育分析支持了粗螋科的基部位置，但也恢复了几个有争议的分支。
