Asopus reciprocus syntype, from the Natural History Museum.

Belongs within: Panheteroptera.
Contains: Acanthosomatidae, Scutelleridae, Tessaratomidae, Cydnidae, Pentatominae.

The Pentatomoidea include the stink bugs and related taxa. Many pentatomoids have an enlarged scutellum, which in extreme cases may cover the entire abdomen. Such examples include the Plataspididae, in which the hemelytra are much longer than the body but folding to fit under the scutellum at rest. Members of the Plataspididae are found in warmer regions of the Old World. Lestonia is an endemic Australian genus that has been collected on growing tips of the native cypress Callitris; members of this genus have the margins of the head, pronotum and part of the costal margins of the hemelytron expanded and recurved to give a tortoise-like appearance (Carver et al. 1991).

Most pentatomoids are plant-feeders but members of the pentatomoid subfamily Asopinae are predators, and have a thick rostrum associated with bucculae that are shorted to allow greater flexibility of the labium for predation. Other distinctive members of the group include the east Asian genus Parastrachia, including two species of large, strikingly red and black bugs with a distinctive subsocial mode of behaviour through progressive provisioning (Sweet & Schaefer 2002). The tropical Urostylinae are relatively elongate and delicate compared to other pentatomoids and characterised by cylindrical antennifers set on the lateral margins of the head, entirely visible from above (Carver et al. 1991).

Synapomorphies (from Shcherbakov & Popov 2002): Antennae 5-segmented; only two lateral trichobothria per abdominal segment; genital aperture directed caudally; egg barrel-shaped with circular eclosion rent.
