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]

Genera

These four genera belong to the family Bajanzhargalanidae:

† Bajanzhargalana Storozhenko, 1988 Ulaan-Ereg Formation, Mongolia, Late Jurassic (Tithonian)
† Nele Ansorge, 1996 Grimmen locality, Germany, Early Jurassic (Toarcian)
† Sinonele Cui, Béthoux, Klass & Ren, 2015 Daohugou Formation, China, Middle/Late Jurassic (Callovian/Oxfordian)
(?) † Sylvafossor Aristov, 2004 Koshelevka Formation, Russia, Early Permian (Kungurian)
