A new species of the genus Oxycraspedus Kuschel from the tribe Oxycraspedini (Belidae: Oxycoryninae) is described from late Eocene Baltic amber. Oxycraspedus argetus n. sp. is similar to the extant Oxycraspedus minutus but differs in having the elytral interstriae narrower than the striae, large and dense punctation in the striae, a flattened, non-impressed forehead, more convex body and a rostrum about 1.4 times as long as the pronotum. A new species differs from the Baltic amber Oxycraspedus poinari by having the body covered with white elongate scales, a weak convex body and the first tarsomere without a spine. Extinct weevils of this monophagous in Recent genus indicate the presence of their host plants, belonging to the family Araucariaceae (and probable to the genus Araucaria) in the late Eocene Baltic amber forest.

The presence of fossil bark beetles from the early Cretaceous to the Miocene is discussed. Changes in the diversity of this group over time are presented. Assumptions about trophic relationships are given. Two new species, Hylastes perkovskyi n. sp. from the tribe Hylastini and Chramesus boninoi n. sp. from the tribe Hylesinini, are described, respectively, from Eocene Rovno and Miocene Dominica amber. These are the first records of the genera Hylastes in Rovno amber and Chramesus in Dominican amber. [ABSTRACT FROM AUTHOR]

A new species, Eduardoxenus rasnitsyni n. sp., of the fungus weevil tribe Valenfriesiini (Coleoptera: Anthribidae: Choraginae), is described from Eocene Baltic amber. This new species is similar to E. unicus Legalov, Nazarenko and Perkovsky, 2018 from Rovno amber but differs in the rounded, more convex eyes, wide antennal club, and the lateral carina reaching the middle of the pronotum. This is the first record of the subfamily Choraginae from Baltic amber. [ABSTRACT FROM AUTHOR]

Two new species of the genus Demimaea from the subfamily Curculioninae are described from Rovno amber. Demimaea zherichini n. sp. is similar to the extant Demimaea mori but differs by its black antennae and tarsi, larger body, body lacking dense, white setae, sparsely not coarsely punctate pronotum and its narrower elytral interstriae. Demimaea gratshevi n. sp. differs from D. zherichini n. sp. by its smaller body, its comparatively longer scape extending towards the compound eye and its convex and wide elytral interstriae. This is the first fossil record of the subtribe Demimaeina. Assumptions are made about the presence of Moraceae plant species in the Eocene of Northern and Eastern Europe, particularly the genus Ficus.

A new species, Archaeosciaphilus gyrommatus n. sp. of the subfamily Entiminae, is described from Baltic amber. The new species is similar to A. marshalli but differs in the smaller body sizes, the scape reaching middle of the eye, narrower decumbent elytral scales, weakly convex elytral interstriae and tarsal claws equal in length. The genus Archaeosciaphilus , n. placem. is transferred from the tribe Sciaphilini to the tribe Polydrusini. A list of species from the subfamily Entiminae described from Baltic amber is given. The relationships between the Entiminae fauna of Baltic amber and other Eocene localities are discussed. [ABSTRACT FROM AUTHOR]
