A new genus of the Araucarian-feeding tribe Oxycraspedini (Coleoptera: Belidae) from Eocene Baltic amber

The new genus, Bojebenzonia n. gen. and its species B. karinae n. sp. from the tribe Oxycraspedini (Belidae: Oxycoryninae) are described from late Eocene Baltic amber. Bojebenzonia differs from the genus Oxycraspedus by its tibiae lacking apical spurs, subparallel pronotal sides, weakly convex body, and wide tibiae. A list of fossil species of the subfamily Oxycoryninae and a key to tribes and subtribes of the subfamily Oxycoryninae are given. It is suggested that the new genus developed feeding on either the family Araucariaceae or Doliostrobaceae. Trophic associations of extant Oxycoryninae are briefly discussed.
