The paper contains a review of coleopteran genera known from Baltic, Bitterfeld and Rovno amber localities. Altogether 420 genera (191 extinct and 229 extant) from 78 families are listed from these three Lagerstatten (as of 7 March 2017). The listed beetles were analyzed zoogeographically and distributional maps for 72 genera were compiled. One-quarter (56) of the genera that have survived since the Eocene have cosmopolitan ranges at present; 35 extant genera have been extripated from the… 
A new fossil species of Attagenus Latreille (Coleoptera: Dermestidae) in Rovno and Baltic ambers, with a brief review of known fossil beetles from the Rovno amber Lagerstätte
Abstract. Based on two specimens originating from Eocene Rovno and Baltic ambers, Attagenus (Aethriostoma) gedanicissimus sp. nov. is described, illustrated and compared with the related fossil
Unexpected palaeodiversity of omaliine rove beetles in Eocene Baltic amber (Coleoptera, Staphylinidae, Omaliinae)
Five new extinct species of four genera in three tribes of the subfamily Omaliinae of Baltic amber are described and illustrated, further reinforcing the coexistence of thermophilous and temperate-loving beetles in Baltic amber and potentially indicating wetland and riparian habitats of amber-producing forests.
The first fossil Microweiseini (Coleoptera: Coccinellidae) from the Eocene of Europe and its significance for the reconstruction of the evolution of ladybird beetles
Analysis of the distribution of Microweiseini genera leads to the conclusion of a possible Gondwanan origin of the tribe and comparison of the diversity of the ladybird beetles from modern ecosystems with those known from Baltic amber suggests substantial differences between these communities and a recent radiation of modern fauna.
The first described turtle beetles from Eocene Baltic amber, with notes on fossil Chelonariidae (Coleoptera: Byrrhoidea)
These are the first formally described species of turtle beetles from Eocene Baltic amber and the first known European representatives of this family and the presence of the plants with which their larvae are associated (epiphytic orchids) is proposed in the Eocene amber forest.
New genus and species of Lamprosomatinae (Coleoptera: Chrysomelidae) from Eocene Baltic amber

The diverse fossil Lamprosomatinae representatives provide strong evidence for the presence of thermophilic, humid and mixed forest, and indicative of warm temperate, humid, equable climate with reduced thermal seasonality in the Eocene Europe.
A second fossil species of the enigmatic rove beetle genus Charhyphus in Eocene Baltic amber, with implications on the morphology of the female genitalia (Coleoptera: Staphylinidae: Phloeocharinae)
Another new Charhyphus species is described and illustrated, and X-ray micro-computed tomography is succeeded in visualising not only the general habitus but also each individual body part, recovering a previously undocumented sclerite on the female internal genital segments in the genus.

Three new genera and species of flea beetles (Chrysomelidae: Alticini) are described from the lowermost Eocene Cambay amber of India, with similarities to Afrotropical elements interpreted to be a result of Neogene migrations from Laurasia to Africa.
Cretaceous beetles (Insecta: Coleoptera) in amber: the palaeoecology of this most diverse group of insects
It is argued that saproxylicity was the most common feeding strategy for these fossil beetles and fungivorous species appear to dominate, and it is necessary to identify alternative abiotic or biotic processes that are responsible for the copious resin production at this time.
The first extinct species of Acritus LeConte, 1853 (Histeridae: Abraeinae) from Eocene Baltic amber: a microscopic beetle inclusion studied with X-ray micro-computed tomography
The current finding expands the range of known Histeridae diversity from the Eocene “amber forests” of Europe and includes the first extinct member of the subfamily Abraeinae (Histeridae) and the smallest known fossil histerid specimen.
Baltic amber Staphylinini (Coleoptera: Staphylinidae: Staphylininae): a rove beetle fauna on the eve of our modern climate
The Staphylinini fauna of Middle Eocene Europe combined thermophilic, freeze-intolerant lineages with freeze-tolerant, temperate lineages and, unlike most other staphyl inid or beetle lineages, all have since become extinct in the Palaearctic region.


New fossil paussids from Dominican amber with notes on the phylogenetic systematics of the paussine complex (Coleoptera: Carabidae)
The temporal and geographical distribution of Protopaussus indicates that its present zoogeographical range may represent the relict of a wide Laurasian distribution in the past, and does not support the previously suspected Oriental centre of origin for the ancestral stock of {Protopaussedinae + Paussinae}.
First records of Chevrolatiini and Cephenniini in Eocene Baltic amber (Coleoptera, Staphylinidae, Scydmaeninae).
Fossils of two tribes of the ant-like stone beetles, previously unknown in Eocene deposits, are recorded, based on inclusions in Baltic amber, the first record of a fossil of Chevrolatiini and Cephennodes sp.
Sciadopitys cladodes from Eocene Baltic amber
The fossil Sciadopitys cladodes provide new insights into the conifer diversity of the ‘Baltic amber forest’ and broaden the picture of its palaeoecology, indicating the presence of humid swamp to raised bog habitats.
The Quaternary arthropod fauna of Greenland: a review with new data
Arthropod fossils from Quaternary deposits in Greenland are considered. The few occurrences of Early and Middle Pleistocene age have yielded only three species of barnacles. This contrasts sharply
Revision of the New World and south‐east Asian Vatellini (Coleoptera: Dytiscidae: Hydroporinae) and phylogenetic analysis of the tribe
A detailed revision of the morphology of members of the tribe is presented along with the description of an abdominal gland system (the ‘speleum’) that is a synapomorphy for the Vatellini.

Coleoptera (beetles) is the most species-rich metazoan order, with approximately 380 000 species. To understand how they came to be such a diverse group, we compile a database of global fossil beetle
Global elevational, latitudinal, and climatic limits for termites and the redescription of Rugitermes laticollis Snyder (Isoptera: Kalotermitidae) from the Andean Highlands
We compile, map, and discuss global elevational, latitudinal, thermal, and rainfall extremes of termite localities from literature sources and unpublished records. Rugitermes laticollis from Ecuador

Molecular phylogeny of Nitidulidae: assessment of subfamilial and tribal classification and formalization of the family Cybocephalidae (Coleoptera: Cucujoidea)
A molecular phylogeny of Nitidulidae based on thirty ingroup taxa representing eight of the ten currently recognized subfamilies supports the following main conclusions and emendations: Cybocephalidae are formally recognized as a distinct family not closely related to Nitidalidae and its constituent taxa are defined.
