A taxonomic review was conducted of the type material of Quedius rove beetles (including Indoquedius, previously a subgenus) described by Otto Scheerpeltz from the 1934 Swedish expedition by René Malaise to Kambaiti, Myanmar. The specimens were mistakenly thought to be lost or compromised during the Second World War, and so the corresponding availa...

OPEN ACCESS: https://resjournals.onlinelibrary.wiley.com/doi/10.1111/syen.12582 The Alticini comprise 601 genera and 10,000 species, including plant pests. Their phylogeny remains largely unresolved, inhibiting taxonomic stability, specimen identification and biological understanding. Here, we generated a genomic dataset using Anchored Hybrid Enri...

Although the Holarctic fauna has been explored for centuries, many questions on its formation are still unanswered. For example, i) what was the impact of the uplift of the Himalaya and Tibetan Plateau?, ii) what were the timings and climate of the faunal bridges connecting the Nearctic and Palearctic regions?, and iii) how did insect lineages resp...

Several phylogenetically isolated, early diverging lineages of rove beetle tribe Quediini, all endemic to the western Nearctic, have recently been revealed by phylogenomic systematics. These three lineages, currently treated as either Quedius (Raphirus) or Q. (Paraquedius) warrant recognition at the genus level in the ongoing effort to achieve reci...

We here present the first integrative revision of the subgenus Quedius Stephens, 1829 sensu stricto where taxonomic decisions are based on morphology, genomic phylogeny (published elsewhere) and single locus DNA evidence. The subgenus is restricted to the Holarctic region and includes some of the largest, most robust members of the genus Quedius. F...

Bolitogyrus is a moderately diverse genus of 78 species that are widely disjunct in the subtropical and tropical forests of the Neotropical and Oriental regions. Following recent revisions of both the Neotropical and Oriental species, this study provides new distributional data, a revised species concept for Bolitogyrus strigifrons (Wendeler) sensu...

Despite their relatively large size and abundance in diverse Nearctic ecosystems, the Paederinae (Staphylinidae) of North America have received only limited taxonomic attention since the early 1900s. In preparation for a revised key to the paederine genera of Canada and the United States, several taxonomic issues highlighted twenty years ago in the...

Sundaquedius gen. nov. (Cyrtoquediini) and Fluviphirus gen. nov. (Indoquediini) are described from southeast Asia and western North America, respectively, resulting in the new combinations Sundaquedius nigropolitus (Cameron) and Fluviphirus elevatus (Hatch). Sundaquedius abbreviatus sp. nov. is described from Vietnam. The phylogenetic positions of...

Anthropogenic climate change is causing the Arctic and Subarctic to warm faster than lower latitudes. Arthropods comprise the majority of animal species and are especially sensitive to abiotic environmental changes. In this chapter we review and discuss impacts of climate change on arthropods, including extinctions and extirpations, population decl...

Rigorous species delimitation is a challenge in biology and systematics in particular. In insects, male genitalia traditionally, and the barcoding region of the CO1 gene recently, are the main markers to identify species, even though a standalone use of CO1 for that is often criticized. In our systematic revision of the mycophagous and in other way...

Click-beetles (Coleoptera: Elateridae) are an abundant, diverse, and economically important beetle family that includes bioluminescent species. To date, molecular phylogenies have sampled relatively few taxa and genes, incompletely resolving subfamily level relationships. We present a novel probe set for anchored hybrid enrichment of 2260 single-co...

Phylogenetic analyses using molecular and morphological data were performed to a...

Rove beetles of the tribe Quediini are abundant predators in humid micro-habitats of forested, open, synanthropic or subterranean ecosystems, with just over 800 species distributed across the temperate and subtropical regions of the Northern Hemisphere. Previous molecular phylogenies included only a limited representation of this diversity but have...

Environmental stress from abiotic conditions imposes physiological limits on individuals within communities, and these stressful conditions can act as a filter on the species present in any given environment. Such abiotic stressors can reduce a community's diversity and make its composition more phylogenetically clustered. Using a decade of staphyl...

ABSTRACT Water scavenger beetles (Coleoptera: Hydrophilidae) are a broadly distributed group with high extant diversity. However, reliable records from Baltic amber (Eocene) are scarce and limited to two undescribed species previously reported in the literature. Here we study these two specimens plus four additional ones. All specimens were sub-opt...

The recognition of Holarctic species, those shared between Nearctic and Palaearctic regions, often implies continuous or recent events of gene flow across the 85-km-wide Bering Strait between Alaska and Russia. During the Pleistocene (2.8–0.012 Mya), the Bering land bridge has provided frequent episodes of continuous, tundra habitat across this bar...

This study demonstrates the power of DNA barcoding to detect overlooked and newly arrived taxa. Sixty-three species of Coleoptera representing 25 families are studied based on DNA barcode data and morphological analysis of the barcoded specimens. Three of the species involve synonymies or previous taxonomic confusion in North America, while the fir...

Despite their familiarity to most naturalists, the large rove beetles of the subtribe Staphylinina are poorly understood systematically and have never been the subject of a focused phylogenetic analysis. Within a total evidence analytical framework, an unusual Staphylinina from China was demonstrated to be the sister group of Ontholestes and was de...

Cenozoic climate cooling, particularly during the Eocene, has drastically shaped modern biological assemblages through a shift from an equable greenhouse to a polarized icehouse. Present-day Europe lies in a highly seasonal and temperate area that strongly embodies this modern icehouse climate. Baltic amber provides a Middle Eocene snapshot of the...

Fourteen species of the genus Boreophilia Benick are now recognized in North America. Boreophilia insecuta (Eppelsheim), reported by Lohse (1990) from North America, is a misidentification of a new species, which is described here as B. neoinsecuta Klimaszewski, sp. n., and the true B. insecuta (Epp.) does not occur in North America. An additional...

Xanthopygina is a group of colourful, neotropical rove beetles (Staphylinidae) comprising 28 genera and more than 350 species. While many genera are found on rotting fruits, carrion, dung and mushrooms, several taxa have evolved associations with social insects. Previous phylogenetic analyses have used only a subset of genera and were based solely...

One hundred and fifty-three of these species, in 73 genera and 13 subfamilies, are confirmed here as adventive; they constitute about 9% of the Canadian fauna and mostly originate from...

Ecosystem engineers, such as social insects, burrowing mammals, and beavers , have a large physical impact on their environment and create new niches for a diversity of organisms. New species or entire lineages of commensal insects have evolved in response to these new microhabitats, and the hyperdiverse rove beetles (Staphylinidae) are no exceptio...

The Staphylinidae, or rove beetles, is one of the largest and most biologically diverse of the beetle families. The world fauna consists of more than 63,495 described species, with more than 1774 species recorded in Canada. By virtue of their sheer abundance, number of species and trophic diversity, rove beetles play important roles in terrestrial...
