Abstract We provide the first multilocus molecular phylogeny of a group corresponding to former subfamily Staphylininae. Results are corroborated by morphological, biogeographical and palaeobiological evidence serve as baseline for an updated suprageneric classification. The Staphylininae is proven be lineage sister monophyletic Paederinae reclassified according robust resolving number long‐standing controversies. Xantholininae (revised status) reinstated contain tribes Xantholinini,...

Abstract Baltic amber is a rich source of fossilized organisms and valuable tool for evolutionary, biogeographical palaeoenvironmental research. Because it found in several deposits around the Sea, exact area origin, age Eocene palaeoenvironment forest form subject ongoing discussion. Furthermore, there puzzling connection between climate change co‐occurrence thermophilic temperate insect taxa amber, sometimes even same inclusions. We revisit these issues through new piece evidence: rare...

Abstract Cenozoic climate cooling, particularly during the Eocene, has drastically shaped modern biological assemblages through a shift from an equable greenhouse to polarized icehouse. Present-day Europe lies in highly seasonal and temperate area that strongly embodies this icehouse climate. Baltic amber provides Middle Eocene snapshot of European fauna before large-scale change. Here, we focused on rove beetle tribe Staphylinini conducted comprehensive phylogenetic study all known fossils...

Abstract The Sternorrhyncha, which comprise about 18,700 described recent species, is a suborder of the Hemiptera, one big five most diverse insect orders. In modern fauna, these tiny phytophages insects great ecological and economic importance, like aphids (Aphidomorpha), scale (Coccidomorpha), whiteflies (Aleyrodomorpha) psyllids (Psylloidea). Their evolutionary history can be traced back to Late Carboniferous, but early stages their evolution diversification poorly understood, with two...

The myrmecophilous Paederinae rove beetle genus Megastilicus Casey, 1889 from North America is reviewed based on museum specimens. Prior to this study, the was monotypic with one species formicarius described. Here, we provide a redescription of and type species, designate lectotype, pictures habitus illustrations aedeagus genital segments. Additionally, describe new for genus, iowaensis sp. nov., include an identification key two present distribution map both them, including state records....

Aulieezidium karatauense, a new genus and species of the extinct planthopper family Fulgoridiidae is described from Upper Jurassic deposits Karabastau Formation Aulie, Karatau (Southern Kazakhstan Province, Kazakhstan). The characters in respect to other genera placed are reviewed. palaeoecological palaeogeographical data concerning gen. n. also discussed.

A new representative of the family Chaulioditidae (Insecta, Grylloblattida), Chauliodites niedzwiedzkii sp. n., is described from Upper Olenekian-Lower Anisian sediments Pałęgi in Holy Cross Mountains, Poland. This first formal description any fossil insect area.

Abstract Stenus is the largest genus of rove beetles and second among animals. Its evolutionary success was associated with adhesive labial prey-capture apparatus, a unique apomorphy that genus. Definite apparatus are known from Cenozoic fossils, while age early evolution Steninae hardly ever hypothesized. Our study several Cretaceous Burmese amber inclusions revealed stem lineage possibly possesses -like apparatus. Phylogenetic analysis extinct extant taxa putatively allied subfamilies...

Aphidoidea, the so-called "true aphids" are one of most challenging groups in terms solving phylogenetic relationships. Morphology-based analyses were strongly affected by widespread homoplasy, while molecular-based attempts struggled with lack sufficient signal. Despite significant improvements, higher classification still remains unresolved and rather controversial. However, use fossil record, valuable sources information, was mainly limited to calibration a tree, without direct inclusion...

Abstract The fossil record contains vital information about the evolution of lineages and is a source data that cannot be reconciled other than by direct observation morphologies. Total‐evidence phylogenetic reconstruction being increasingly used to assess position extinct taxa incorporating morphological from extant together with molecular in united framework. Here we apply method two Cretaceous Burmese amber inclusions belonging rove beetle subfamily Paederinae. To perform total evidence...

Abstract Phylogenetic studies of Aleocharinae rove beetles, arguably one the least known and largest insect lineages, are compromised by its enormous taxonomic diversity. DNA, a powerful resource for phylogenetics, is not available numerous extant aleocharine species. We provide broad comparative morphological study to frame molecular datasets total‐evidence analyses. Using full‐body dissections slide‐mounting techniques light microscopy supplemented scanning electron microscopy, we...

Paederinae, a diverse subfamily of rove beetles (Staphylinidae), is poorly explored with an outdated subtribal and generic classification lacking proper phylogenetic perspective. Therefore, the discovery two Baltic amber fossil specimens resembling genera Micrillus Scymbalium, which are particularly challenging in terms systematics, called for thorough analysis to infer their position ecological requirements. The fossils were examined light microscopy supplemented by X-ray micro-computed...

Army ants provide nourishment to a large variety of animals. This includes birds that feed on animals flushed out by army ant raids, symbiotic arthropods consume the ants' prey or their brood, and other scavenge refuse deposits. The latter have not received much attention, few published studies lack detailed species identifications. Here we first systematic inventory beetle fauna associated with deposits

Abstract The rove beetle tribe Amblyopinini (Coleoptera: Staphylinidae: Staphylininae) is a recently discovered monophyletic lineage comprising an estimated 1000 or more species of mainly leaf‐ and log litter‐dwelling predatory insects found throughout the southern hemisphere. Of these, single genus Heterothops Stephens somehow conquered all continents in northern hemisphere as well. A few lineages amblyopinines independently evolved into highly derived predators mammal ectoparasites from...

Abstract In order to classify and taxonomically describe the first two fossil Othiini (Coleoptera: Staphylinidae: Staphylininae) species from three well‐preserved specimens in Cretaceous Burmese amber, a phylogenetic analysis was conducted, combining extant extinct taxa. A dataset of 76 morphological characters scored for 33 recent across subfamilies Staphylininae Paederinae analysed using maximum parsimony Bayesian inference methods. The many differing hypotheses higher‐level relationships...

Abstract A revision of the J urassic aphid family G enaphididae revealed that type genus Genaphis did not have characteristics usually attributed to this family. This discovery led a series taxonomic decisions. The diagnosis is emended. genera Aphaorus , Juraphis and Pterotella are moved uraphididae, fam.n. new included in superfamily P alaeoaphidoidea. Additionally, two species, karataviensis sp.n. shartegensis described. Phylogenetic relationships among taxa position family, distribution...

Bayesian total-evidence approaches under the fossilized birth-death model enable biologists to combine fossil and extant data while accounting for uncertainty in ages of specimens, an integrative phylogenetic analysis. Fossil age is a key feature record as many empirical sets may contain mix precisely dated poorly specimens or deposits. In this study, we explore whether reliable estimates can be obtained from analyses model. Through simulations based on example Baltic amber deposit, show...

Abstract The ecology of extinct species from the Cretaceous is largely unknown. Morphological features specimens preserved in amber can help to reveal habitats and evolutionary strategies that occurred fossil lineages. An unusually small rove beetle (Staphylinidae) subfamily Paederinae with a Y-shaped suture on head modified tarsi antennae newly described here as Midinudon juvenis Tokareva & Żyła gen. et sp. nov.
