Heteroptera

 Gamostolus subantarcticus, from Michigan Science Art.

Belongs within: Heteropteroidea.
Contains: Panheteroptera, Gerromorpha.

The Heteroptera include the so-called ‘true bugs’, united by the reduction of the tentorium and the presence in nymphs of scent glands on tergites 3 to 7 (Grimaldi & Engel 2005). The name ‘Heteroptera’ derives from the differentiated wings of many true bugs but this feature is actually characteristic of a derived subgroup of the Heteroptera (the Panheteroptera) whereas other basal lineages retain undifferentiated wings.

Living bugs other than the Enicocephalidae are united as a clade, the Euheteroptera, by mostly reductional synapomorphies including the loss of the proximal crossvein in the fore wing and reduction of the ambient vein, especially posteroapically, and migration of the ventral scent gland openings anteriorly to the thorax. The Enicocephalidae are a primarily tropical and subtropical group of bugs with raptorial fore legs, and the head transversely bilobed with the ocelli on the hind lobe (Carver et al. 1991). Some authors have divided the enicocephalids between distinct families Enicocephalidae and Aenictopecheidae with the former having the pronotum divided by transverse sulci into three distinct laterally constricted areas. The Actinoscytinidae are a fossil family known from the Late Permian to Early Jurassic that may represent stem-group Panheteroptera (Gross 1975).
