Morphological and palaeoecological aspects of fossil insects unveiled by UV-A light.

Studying insect fossils, particularly those preserved as compressions in sedimentary matrices, can be difficult due to the taphonomic processes that often result to poor preservation and contrast of structures compared to the embedding matrix. To address this, we propose a user-friendly and simple methodology based on UV-light to study insect fossils and select specimens of interest for more advanced imagery exploration. While UV-light imaging has been previously applied to compressions of arthropod fossils, it typically involved laser light sources.

A New Genus of Praeaulacidae (Hymenoptera: Evanioidea) from Mid-Cretaceous Kachin Amber: Insights into a Putative New Praeaulacinae Subclade.

A new praeaulacid genus and species, gen. et sp. nov.

The Angiosperm Terrestrial Revolution buffered ants against extinction.

With ~14,000 extant species, ants are ubiquitous and of tremendous ecological importance. They have undergone remarkable diversification throughout their evolutionary history. However, the drivers of their diversity dynamics are not well quantified or understood.

Multiple drivers and lineage-specific insect extinctions during the Permo-Triassic.

The Permo-Triassic interval encompasses three extinction events including the most dramatic biological crisis of the Phanerozoic, the latest Permian mass extinction. However, their drivers and outcomes are poorly quantified and understood for terrestrial invertebrates, which we assess here for insects. We find a pattern with three extinctions: the Roadian/Wordian (≈266.

Phylogenomic Analyses of the Tenthredinoidea Support the Familial Rank of Athaliidae (Insecta, Tenthredinoidea).

The systematic status of the genus and related genera is a perennial controversy in sawfly taxonomy. Several authors have hypothesized that the placement of within the Tenthredinidae is artificial, but no studies have focused on this topic. If the hypothesis that does not belong to Tenthredinidae can be supported, the taxonomic framework of Tenthredinoidea needs revision.

Beautiful wing coloration pattern in a new doratomantispine species (Neuroptera: Mantispidae) from the mid-Cretaceous Burmese amber.

A new species, namely Doratomantispa pouilloni sp. nov., of the mantidfly subfamily Doratomantispinae, is described and illustrated from a complete individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar.

The First Fossil Representatives of the Sawfly Genera and from the upper Miocene of France (Hymenoptera, Tenthredinidae).

sp. nov., first fossil representative of this genus, is described from the upper Miocene of the diatom paleolake of Montagne d'Andance (Ardèche, France).
