Nausibius
Nausibius is a genus of silvanid flat bark beetles in the family Silvanidae. The genus is cosmopolitan with extant representatives worldwide. A fossil species, Nausibius radchenkoi, has been described from Eocene Rovno amber, confirming the genus originated at least 34 million years ago and was present in European forest ecosystems. Extant species are frequently associated with stored food products, particularly sugar.
