Bajanzhargalanidae

Bajanzhargalanidae is an extinct family of winged polyneopteran insects, recorded from the Permian and Jurassic but not the Triassic. They are considered poorly known members of the "Grylloblattida", a poorly defined group of extinct insects thought to be related to modern ice crawlers (Grylloblattidae).^[1] There are at least four genera and about seven described species in Bajanzhargalanidae.^[2][3][4][1]
