Abstract
Abstract. The new weevil genus Igneonasus gen. nov. (type species: I. rudolphi sp. nov.) of the tribe
Ceutorhynchini (Curculionidae: Conoderinae: Ceutorhynchitae) is described
from the late Oligocene of Fossillagerstatte Enspel, Germany. The new
genus differs from the similar genus Stenocarus Thomson, 1859 in the anterior margin
of the pronotum, which is not raised, a pronotum without tubercles on the
sides, and a femur without teeth. This weevil is the largest representative
of this supertribe and 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.
