Eudermaptera

 Male European earwig Forficula auricularia, photographed by Eugene Zelenko.

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 the tarsi is ventrally produced below the third but members of the Labioidea retain a simple, subcylindrical second tarsal segment. Forficulidae have the second tarsal segment expanded laterally as well as produced (Rentz & Kevan 1991). The European earwig Forficula auricularia has become distributed almost worldwide in association with humans (Rentz & Kevan 1971).

The Labioidea are now regarded as including the genus Arixenia, specialised cave-dwellers found in bat-roosts in southeast Asia that feed on guano and (in the case of A. esau) perhaps facultatively on the bats themselves (Askew 1971). Nesogaster is a labioid genus distinguished by the possession of smooth tegmina bearing lateral keels (Rentz & Kevan 1991).
