Eodermaptera Explained

Eodermaptera is an extinct suborder of earwigs known from the Middle Jurassic to Mid Cretaceous. Defining characteristics include "tarsi three-segmented, tegmina retain venation, 8th and 9th abdominal tergite in females are narrowed, but separate from 10th tergite and not covered by 7th tergite and exposed ovipositor"^[1] They are considered to be more closely related to Neodermaptera than the more basal Archidermaptera.^[2]
