Abstract
Austronausibius aenigmatista sp. nov., the first fossil silvanid beetle belonging to the Recent genus Austronausibius Halstead distributed in Australia and southern South America, is described from late Eocene Rovno amber. The new fossil species is illustrated and compared with related extant and morphologically close extinct taxa. A key to species of fossil Silvanidae known from Eocene East European amber (Baltic and Rovno) is provided.
