New insects from the Permian of Catalonia (Spain) predate the early diversification of Triassic clades adapted to arid environments (Grylloblattodea, Probnidae, Dictyoptera)

Probnis sauvanyaensis sp. nov., the first representative of the ‘ grylloblattodean’ family Probnidae from the Iberian Peninsula, is described from the middle to? upper Permian outcrop of Sauvanyà in the Catalan Pyrenees. The family is otherwise represented by two additional species of Probnis from the? middle Permian of the USA and by a single genus and species from the? Lower Triassic of Ukraine.

As is known from outcrops with rather extreme climates, the family may have survived the global warming of the Permian – Triassic crisis. We also describe a roachoid of the family Spiloblattidae from the same outcrop as the second representative of this family from the Iberian Peninsula.
