Short summary
The new weevil Igneonasus rudolphi gen. et sp. nov. of the tribe Ceutorhynchini is described from the late Oligocene of Fossillagerstätte Enspel, Germany. The new genus is similar to the Recent genus Stenocarus and the largest representative of the supertribe Ceutorhynchitae. It is the first fossil Curculionidae species described from the paleolake Enspel. In this ancient ecosystem, weevils were at least sometimes an important food resource for the cyprinid fish Palaeorutilus enspelensis.
