Summary: This study revises the taxonomy of the arboreal carabid beetle genus Parena, providing keys and descriptions for the identification of different subgenera, species groups, and species. It also proposes several new synonyms and describes eight new species. The previous taxonomy was flawed, and this study rectifies the classifications based on morphological characters and examination of type materials. The inclusion of diagnostic characters, distribution maps, and illustrations enhances the understanding of this beetle genus.

Summary: This article describes two new species of soldier beetles (Malthinus masoni sp. nov. and Malthodes markpankowskii sp. nov.) discovered in Baltic amber. Their discovery provides further evidence of the abundant diversity of soldier beetles in Europe during the Eocene, which can likely be attributed to the warmer climate during that epoch and the presence of various habitats where Baltic amber formed.

Summary: Advancements in computational and tomographic methods have allowed for detailed descriptions of fossil specimens in amber. This study focused on reconstructing the morphology of a new species of the beetle family Ptilodactylidae from Eocene Baltic amber using X-ray microcomputed tomography. The discovery sheds light on the paleodiversity and evolution of the family as well as the faunal composition of the European Eocene amber forests.

Summary: A new species of Priochirus (Eopriochirus) from mid-Cretaceous amber in Myanmar is described, which enriches the fossil record of Osoriinae and contributes to the understanding of its ancient origin and diversification. With the discovery of this new species, a total of 3 species of osoriines have been found in Mesozoic Kachin amber.

Summary: A new polypore fungus beetle species E. praecursor is described based on well-preserved Baltic amber specimens. It is the first member of the subfamily Eustrophinae from the Cenozoic era. This fossil discovery expands the diversity of Tetratomidae in the Eocene "amber forest".

Summary: A new genus and species of fossil darkling beetle, Archaeoluprops groehni gen. et sp. nov., is described from the Eocene Baltic amber. It closely resembles species of the Lupropini and Goniaderini tribes in external morphology but differs in lacking intersegmental membranes between abdominal ventrites 3-5 and defensive glands. Based on its combination of primitive and derived characters and distinctions from other extinct and extant lagriine tribes, a new tribe, Archaeolupropini trib. nov., is established. The absence of Baltic amber lagriine tribes in extant fauna of middle latitudes in Europe is noted.

Summary: New fossil species of the genus Diapus are described in Miocene amber from Ethiopia and Zhangpu, China. The large number of Diapus specimens found in Zhangpu amber supports the paleoenvironmental reconstruction of a megathermal seasonal rainforest. The discovery of these new species suggests that the diversification of the Platypodinae genus Diapus, potentially associated with angiosperms, may have started in the Cretaceous and increased in diversity during the Miocene. These specimens represent the first record of Diapus preserved in amber.

Summary: Throscidae is a relatively small lineage in the beetle superfamily Elateroidea, with sparse fossil records in the Mesozoic. Three new species found in mid-Cretaceous Burmese amber indicate a high diversity of Throscidae during the Cretaceous period. These new findings greatly extend the Mesozoic diversity of Throscidae and suggest a high degree of morphological disparity for this family in the Cretaceous.

Summary: This article redescribes the subgenus Mimodromius (Chubutianus) and its two known species, and describes four new species. The subgenus is recorded for the first time in Chile and has a restricted distribution area in the South American Transition Zone.

Summary: This article describes a new extinct fungus beetle species found in Baltic amber, belonging to the extant Palaearctic genus Leiestes Chevrolat. The species was studied and illustrated in detail using X-ray micro-computed tomography (μCT), and a list of described Endomychidae species known from fossil resins (Baltic, Bitterfeld, Oise and Burmese ambers) was compiled.

Summary: This study presents the discovery of a Baltic amber bead in a Late Neolithic funerary cave in northeastern Iberia. Spectroscopic analysis confirmed its complete resemblance to Baltic succinite amber. This finding provides the earliest evidence for the arrival of Baltic amber in the Mediterranean and Western Europe, challenging the traditional timeline.

Summary: This study re-evaluated molecular clock analyses, resetting it based on fossil evidence and the Gondwanan split. By recalibrating and improving prior choices, the origin of the genus Carabus was found to be roughly 30 million years older than previously thought.

Summary: Two new species of the carabid genus Deltomerodes are described from Xizang (China): D. ovicollis sp. nov. (type locality: Doxong La, Medog) and D. conaensis sp. nov. (type locality: Rama La, Cona). The new species are well described, illustrated, and their distributions are mapped. An updated key to all eight known Chinese Deltomerodes species is provided.
