五翅目昆虫是真正昆虫(半翅目：异翅目)的第二大基础类群，包括许多重要的农业和林业害虫，其较高级别的系统发育已经争论了几十年。为了研究五形目的系统发育和进化史，我们通过对混合基因组DNA的下一代测序，构建了46个物种的新线粒体基因组。基于比以前广泛得多的分类单元样本，使用地点-异质混合模型(CAT+GTR)的贝叶斯分析将五角形目的更高级别的系统发育解析为(Aradoidae+(五角形总科+(Coreoidea+(Lygaeoidae+Pyrrhocoroidae)。在金龟总科的共同祖先中，有一个从trnT/trnP到trnP/trnT的转变，这表明这种基因重排可能是金龟科的一个同源异型。分歧时间分析估计，五形目起源于中三叠世约242 Ma，大多数已识别的超家族起源于中侏罗世至早白垩世。在早白垩世，五角形目中的科的多样化与被子植物的辐射很大程度上是一致的。
The higher-level phylogeny of Pentatomomorpha, the second largest infraorder of true bugs (Hemiptera: Heteroptera), which includes many important agriculture and forestry pests, has been debated for decades. To investigate the phylogeny and evolutionary history of Pentatomomorpha, we assembled new mitochondrial genomes for 46 species through next-generation sequencing of pooled genomic DNA. Based on a much broader taxon sampling than available previously, Bayesian analyses using a site-heterogeneous mixture model (CAT+GTR) resolved the higher-level phylogeny of Pentatomomorpha as (Aradoidea + (Pentatomoidea + (Coreoidea + (Lygaeoidea + Pyrrhocoroidea)))). There was a transition from trnT/trnP to trnP/trnT in the common ancestor of Pyrrhocoroidea, which indicates that this gene rearrangement could be an autapomorphy for Pyrrhocoroidea. Divergence time analyses estimated that Pentatomomorpha originated c. 242 Ma in the Middle Triassic, and most of the recognized superfamilies originated during the Middle Jurassic to Early Cretaceous. The diversification of families within Pentatomomorpha largely coincided with the radiation of angiosperms during the Early Cretaceous.
