5–7, see text The Pentatomomorpha comprise an infraorder of insects in the true bug order Hemiptera.

They play an important role in agriculture and forestry industries and they are also used as controlling agents in studies.

The Aradoidea represent the most basal extant lineage, while the others, often united as clade Trichophora, are more modern:[2][3][1] Among these, the Pentatomoidea seem to represent a by and large monophyletic lineage as traditionally understood, while the other three form a close-knit group and are in serious need of redelimitation.

[1] The Idiostolidae are usually considered a family of the Lygaeoidea, but in the past have been placed in a distinct monotypic superfamily Idiostoloidea, for example.

The Piesmatidae, usually placed in the Lygaeoidea also, are sometimes considered incertae sedis,[4] or placed in a monotypic superfamily Piesmatoidea with the discovery of Cretopiesma.
