Eudermaptera

Belongs within: Neodermaptera. The Eudermaptera are a clade of earwigs characterised by the reduction of the male genitalia to a single penal lobe and single virga, and having the expanded regions of the anal and intercalary veins distinctly separated (Grimaldi & Engel 2005). In members of the families Chelisochidae and Forficulidae, the second segment of… Continue reading Eudermaptera

Forficulida

Belongs within: Polyneoptera.Contains: Archidermaptera, Neodermaptera. The name Forficulida is used here as in Shcherbakov (2002) for the clade uniting the Dermaptera (earwigs) with the fossil, paraphyletic ‘Protelytroptera’. First recorded from the Lower Permian, the forficulids are distinguished by having their forewings hardened, with the sutural margins overlapping in repose, and the hindwings transversely folded when… Continue reading Forficulida

Archidermaptera

Belongs within: Forficulida. The Archidermaptera are a basal, fossil group within the Dermaptera (earwigs) known from the late Triassic to the early Cretaceous. The group is defined solely by plesiomorphic characters and may be paraphyletic. Archidermapterans had the shortened, hardened forewings (tegmina) of modern earwigs, but the tegmina still retained some veins and the cerci… Continue reading Archidermaptera

Neodermaptera

Belongs within: Forficulida.Contains: Anisolabididae, Eudermaptera. The Neodermaptera are the crown group of the earwigs, dating back to the late Jurassic or early Cretaceous. They are readily distinguished from other living insects by the cerci being modified into a large pair of forceps at the end of the abdomen; they also have the front wings modified… Continue reading Neodermaptera
