G. Lyubarsky and E. Perkovsky

The First Eocene Species of the Genus Cryptophagus (Coleoptera, Clavicornia, Cryptophagidae)

Based on a fossil specimen from the Late Eocene Rovno amber (Ukraine), Cryptophagus harenus Lyubarsky et Perkovsky, sp. n., an Eocene species of this genus is described. The new species is similar to the extant desert species Cryptophagus desertus Lyubarsky and C. recticollis Solsky, differing by the large callosity occupying 1/4 length of lateral margin of pronotum.

New Species of Stilbus (Coleoptera, Clavicornia, Phalacridae) from the Late Eocene Rovno Amber

The first Eocene species of Stilbus Seidlitz, 1872, S. bedovoyi Lyubarsky et Perkovsky, sp. n., is described from Late Eocene Rovno amber. S. bedovoyi is most similar to Stilbus atomarius (Linnaeus) and differs from it by smaller body size, strong and large punctation of elytra, and broadly oval apex of elytra.

G. Yu. Lyubarsky and E. E. Perkovsky

Atomaria gedanicola Lyubarsky et Perkovsky, sp. n., a new cryptophagid species from Baltic amber is described. The new species is the first recorded Eocene Atomariinae. The new species is similar to A. fuscipes Gyllenhal. It differs from the latter in having pronotum flat, posterior angles of pronotum obtuse, and antenna short. The record of A. gedanicola syninclused with Ceratopogon biting midge supports the Late Eocene age of the Baltic amber, for the Holarctic affinities of both taxa are incompatible with the paratropical climate characteristic of the Mid-European Middle Eocene.
