Abstract

This work presents the results of a taxonomic study carried out on three specimens of fossil Orthoptera from the Crato Member laminated limestone, lowest unit of the Santana Formation (Lower Cretaceous), Araripe Basin. All fossils were found in Pedra Branca Quarry, near Santana do Cariri and Nova Olinda municipalities in Ceará State, northeast Brazil. The following new taxa are proposed: Brauckmannia groeningae Martins-Neto, n. gen. et n. sp. (Brauckmanniidae Martins-Neto, n. fam.), Euclydes ramosfernandesi n. gen. et n. sp. (Mimnermidae: Euclydesinae Martins-Neto, n. subfam.), and Prezottophlebia helbae Martins-Neto, n. gen. et n. sp. (Hagloidea: Prezzottophlebiidae Martins-Neto, n. fam.). The meaning of their morphological characters (robustness and body shape) and their presence in the laminated limestone is discussed like a contribution to the past distribution of Ensifera and to the paleoecological inferences.

Key words: Ensifera, Santana Formation, Araripe Basin, Lower Cretaceous, Brazil.
