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.ΠΠ΅ΡΠ²ΡΠΉ ΡΠΎΡΠ΅Π½ΠΎΠ²ΡΠΉ Π²ΠΈΠ΄ ΡΠΎΠ΄Π° Stilbus Seidlitz, 1872 β S. bedovoyi Lyubarsky et Perkovsky ΠΎΠΏΠΈΡΠ°Π½ ΠΈΠ· ΠΏΠΎΠ·Π΄Π½Π΅ΡΠΎΡΠ΅Π½ΠΎΠ²ΠΎΠ³ΠΎ ΡΠΎΠ²Π΅Π½ΡΠΊΠΎΠ³ΠΎ ΡΠ½ΡΠ°ΡΡ.

Fourth Contribution on Late Eocene Amber Silken Fungus Beetles: a New Baltic Amber Species of Atomaria (Coleoptera, Clavicornia, Cryptophagidae)
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.ΠΠΏΠΈΡΠ°Π½ Π½ΠΎΠ²ΡΠΉ Π²ΠΈΠ΄ ΠΊΡΠΈΠΏΡΠΎΡΠ°Π³ΠΈΠ΄ ΠΈΠ· Π±Π°Π»ΡΠΈΠΉΡΠΊΠΎΠ³ΠΎ ΡΠ½ΡΠ°ΡΡ β Atomaria gedanicola Lyubarsky et Perkovsky, sp. n.

The First Eocene Species of the Genus Micrambe (Coleoptera, Clavicornia, Cryptophagidae)
Based on a fossil specimen from the Late Eocene Rovno amber (Ukraine), Micrambe sarnensis Lyubarsky et Perkovsky, sp. n., the first Eocene species of this genus is described. The new species is similar to the extant Micrambe abietis (Paykull) and M. ulicis (Stephens), differing by having the callosity with an acutangular caudolateral corner.ΠΠ· ΠΏΠΎΠ·Π΄Π½Π΅ΡΠΎΡΠ΅Π½ΠΎΠ²ΠΎΠ³ΠΎ ΡΠΎΠ²Π΅Π½ΡΠΊΠΎΠ³ΠΎ ΡΠ½ΡΠ°ΡΡ (Π£ΠΊΡΠ°ΠΈΠ½Π°) ΠΎΠΏΠΈΡΠ°Π½ Micrambe sarnensis Lyubarsky et Perkovsky, sp. n. β ΠΏΠ΅ΡΠ²ΡΠΉ ΡΠΎΡΠ΅Π½ΠΎΠ²ΡΠΉ Π²ΠΈΠ΄ ΡΠΎΠ΄Π°.
