Zygentoma

Ancient Greek: coined for purposes of taxonomy in late 19th century. Derived from the Ancient Greek ζυγόν (zugón) in context meaning "yoke" or "bridge", and ἔντομα (éntoma) literally "cut into" because of the constrictions in the anatomy of typical insects.[1] The idea behind the name was that the taxon formed a notional link between the Pterygota and the Apterygota.[2] This view is now obsolete, but the phylogeny of the Insecta was in its infancy in the late 19th and early 20th century, and the name was firmly established by the time that more defensible views were developed.
