Mantophasmatidae is a family of carnivorous wingless insects within the monotypic order Mantophasmatodea, which was discovered in Africa in 2001. Recent evidence indicates a sister group relationship with Grylloblattidae, and Arillo and Engel have combined the two groups into a single order, Notoptera, with Grylloblattodea and Mantophasmatodea ranked as suborders.

Grylloblattidae, commonly known as the icebugs or ice crawlers, is a family of extremophile (psychrophile) and wingless insects that live in the cold on top of mountains and the edges of glaciers. It is the only member of Grylloblattodea, which is generally considered an order. Alternatively, Grylloblattodea, along with Mantophasmatodea, have been ranked as suborders of the order Notoptera. Grylloblattids are wingless insects mostly less than 3 cm long, with a head resembling that of a cockroach, with long antennae and having elongated cerci arising from the tip of their abdomen. They cannot tolerate warmth and many species have small distribution ranges.
