Abstract: Cratonepa enigmatica gen. and sp. nov., an enigmatic new nepoid bug, is described from the Lower Cretaceous Crato formation in Brazil. Although its general habitus is strikingly similar to that of the Cenozoic and recent Nepidae, it has several plesiomorphic characters, the most obvious being the siphon retractiled into the abdomen, which supports a basal position as a sister group of either all Nepidae or even Nepoidea. The morphology of its legs suggests that it was a walking predator living in mud or in aquatic vegetation, as for extant Nepidae, although the absence of a long siphon suggests a very different way of breathing.

The new genus and species of scoliid wasp Araripescolia magnifica Nel, Escuillie & Garrouste, gen. et sp. nov. is described from the Early Cretaceous Crato formation in Brazil. It seems to be more closely related to the modern Campsomerinae than to the other Cretaceous Scoliidae: Archaeoscoliinae and Proscoliinae.
