Changes in the Family Composition of Eoblattid Insects (Insecta: Eoblattida) near the Permian–Triassic Boundary

Changes in composition of the order Eoblattida at the Permian–Triassic boundary are discussed. A new species of Blattogryllidae, Baharellinus orenburgensis sp. nov., is described from the Lower Triassic of the Petropavlovka locality (Orenburg Region, Russia). The family Gorochoviidae (known from the Dzhailoucho locality; Middle or Upper Triassic of the Kyrgyzstan) is transferred from the order Reculida to Eoblattida. Family Batkentakidae fam. nov. is erected for the genus Batkentak Aristov, 2015 from the Dzhailoucho locality. The family composition of eoblattids showed no significant changes at the Paleozoic-Mesozoic boundary.
