Geinitziidae

Geinitziidae is an extinct family of polyneopteran insects, known from the Permian to Cretaceous. They are currently considered to be members "Grylloblattida"^[1] a poorly defined group of extinct insects thought to be related to modern ice crawlers (Grylloblattidae).^[2] Other authors place them in the extinct order Reculida.^[3] Unlike modern ice crawlers, which are wingless, they had large wings, bearing a superficial resemblance to cockroaches, and are thought to have been day-active above ground predators.^[1]
