Abstract
A new, highly specialized family, Rafaelidae, is proposed for two new lacewing-like species from the Lower Cretaceous Crato Formation in the Araripe Basin, Brazil. They have body and wing venation characters that are unique within the neuropterid insects, i.e., head, ovipositor, organization of the radial and median veins and structure of the subcostal vein. This new family cannot be attributed to any known insect order with certainty. These discoveries support the hypothesis of a considerable morphological disparity between neuropterid insects during the Early Cretaceous, as for the Odonatoptera.
