Article: New fossil lacewings and antlions (Insecta, Neuroptera) from the Lower Cretaceous Crato Formation of Brazil
Remarkable new fossil taxa of Neuroptera from the laminated limestone of the Crato Formation, north-east Brazil, are described: Nuddsia longiantennata gen. et sp. nov. (Osmylidae, Gumillinae), the first fossil record of this family from South America, Parapalaeoleon magnus gen. et sp. nov. (Palaeoleontidae), and Triangulochrysopa formosa sp. nov. (Mesochrysopidae). A diagnosis of Gumillinae is provided; Epiosmylidae is considered to be a synonym of this subfamily. A revised diagnosis of Palaeoleontidae is provided, based on a new interpretation of venational characters evident on the exceptionally well-preserved specimen of P. magnus; vein homologies are determined and the fusion of MP and CuA is discussed. The genus Triangulochrysopa has been known previously only from the Lower Cretaceous of Las Hoyas, Spain.
