The second extinct microhisterid species (Coleoptera: Histeridae: Bacaniini) described from the Eocene Rovno amber using X-Ray microtomography

ABSTRACT

The third fossil species of the tribe Bacaniini (Coleoptera, Histeridae), Bacanius caterinoi Sokolov et Perkovsky, sp. nov., is described from the Eocene Rovno amber. Previous two extinct species were known from the Rovno and Baltic amber. We compared the new species with them and extant representatives of related taxa. The new species belongs to the extant genus Bacanius LeConte, 1853 and can be included to the extant subgenus Gomyister Mazur 1984. This is the second species of the subgenus from Rovno amber indicating the diversity of this currently primarily tropical group in the Eocene of Europe.
