Fossil Megaloptera (Insecta: Neuropterida) from the Lower Cretaceous Crato Formation of Brazil.

Two new genera and species of Megaloptera are described from the Lower Cretaceous Crato Formation of Brazil. Cratocorydalopsis brasiliensis gen. et sp. nov. and Lithocorydalus fuscata gen. et sp. nov. are both placed within the family Corydalidae. The specimens represent the first Cretaceous examples of adult megalopteran body fossils not preserved in amber, and are the first megalopterans to be formally described from the Crato Formation.
