Short summary
Although the Mesozoic Era played an important role in the evolution and diversification of Elateridae, the Cretaceous click-beetle fauna remains very poorly known. Here we describe Cretopachyderes burmitinus gen. et sp. nov. based on a single specimen from the mid-Cretaceous Burmese amber. This species is remarkable for its extremely long posterior angles of pronotum, which is a unique character among fossil Elateridae.

A new micro-histerid species is described and illustrated from Eocene Baltic amber. As the first extinct member of the subfamily Abraeinae (Histeridae) and the smallest known fossil histerid specimen, this material was examined using a combination of light microscopy and X-ray micro-computed tomography (μCT). Internal features of the abdomen are well preserved, allowing us to study sclerotized parts of the aedeagus and illustrate these structures in detail.

Baltocar sontagae sp. nov. and Pseudomesauletes lobanovi sp. nov. from the family Rhynchitidae are described from Eocene Baltic amber. It is the first record of Pseudomesauletes from Baltic amber. Keys to species of the genus Baltocar and to the Eocene species of the genus Pseudomesauletes are given. Assumed trophic relationships of the genus Baltocar with Cupressaceae and Pseudomesauletes lobanovi sp. nov. with Rosaceae are discussed.

Short summary
Dascillidae are a species-poor beetle group with a scarce fossil record. Here, we used light microscopy and X-ray microtomography to describe Baltodascillus serraticornis gen. et sp. nov. based on a well-preserved specimen from Eocene Baltic amber. We tentatively place this species in the subfamily Karumiinae. This is the first representative of the Dascillidae formally described from Baltic amber and the first described fossil member of the subfamily Karumiinae.
