Published: March 3, 2025

Untangling the patterns and drivers behind diversification extinction of highly diversified lineages remains a challenge in evolutionary biology. While insect has been widely studied through "Big Four" orders (Coleoptera, Hymenoptera, Lepidoptera Diptera), fifth most diverse order, Hemiptera, often overlooked. Hemiptera exhibit rich fossil record are present-day ecosystems, with many closely associated to their host plants, making them crucial group for studying how past ecological shifts-such as mass extinctions floral turnovers-have influenced diversification. This study leverages birth-death models Bayesian framework estimate diversity dynamics. Our results reveal that global changes flora over time significantly shaped trajectories Hemiptera. Two major faunal turnovers particularly diversification: (i) aftermath Permo-Triassic (ii) Angiosperm Terrestrial Revolution. analyses suggest clades was driven by floristic shifts combined competitive pressures from overlapping niches. Leveraging extensive allowed us refine our understanding across hemipteran lineages.

Abstract Recent progress in beetle palaeontology has incited us to re‐address the evolutionary history of group. The Permian †Tshekardocoleidae had elytra that covered posterior body a loose tent‐like manner. formation elytral epipleura and tight fit abdomen were important transformations Middle Permian, resulting tightly enclosed subelytral space. families likely associated with dead wood gymnospermous trees. end‐Permian extinction event resulted turnover composition faunas, especially decline large‐bodied wood‐associated forms. Adephaga Myxophaga underwent first wave diversification Triassic. Polyphaga are very rare this period. suborder occurs Jurassic, fossils Elateriformia, Staphyliniformia Cucujiformia.

The oldest Rhantus (Coleoptera, Dytiscidae) from the earliest Eocene Fur Formation, Denmark

†Rhantus villumi sp. nov. is described and illustrated on the basis of a single specimen from earliest Eocene Fur Formation, Denmark. With an estimated age ca. 55.4 Ma, it represents oldest member extant genus family Dytiscidae. However, presence Rhantus in early only slightly older than previous estimates, generally agrees well with phylogenetic analyses subfamily Colymbetinae. The predominantly temperate presumably warm Lagerstätte briefly discussed, supporting hypothesis temporary cooling, as suggested by several other invertebrate records Formation.

Phylogenomics resolves the relationships among Hydrophiloidea‐Histeroidea families (Coleoptera) and challenges the single colonization of aquatic habitats

Systematic Entomology, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

Abstract Beetle superfamilies Histeroidea and Hydrophiloidea form a well‐supported monophylum with c. 9000 described species, but the relationships among families remain unresolved, hindering studies of early evolution group. This study presents first genomic data for all modern families, including genomes Synteliidae, Sphaeritidae, Georissidae Epimetopidae. Using datasets 4215, 1100 709 protein‐coding genes, we reconstructed reconfirmed Early Triassic split Histeroidea, revealed to Middle Jurassic origin families. All analytical methods same topology Hydrophiloidea. The superfamily consists two main clades: helophorid lineage (Georissidae + Helophoridae Hydrochidae) hydrophilid (Epimetopidae Spercheidae Hydrophilidae), Hydrochidae Hydrophilidae as strongly supported clades; riparian Epimetopidae branching clades in each lineage. In detected significant conflict phylogenetic signal, indicating more complex dynamic molecular than Hydrophiloidea: our analyses reject Synteliidae sister Histeridae are not decisive on whether Sphaeritidae or other Histeroidea. reconstruction habitat preferences indicated that ancestral inhabited moist substrates at sides lakes rivers were aquatic. Aquatic habitats colonized twice independently: once by an ancestor Hydrophilidae. We discuss evidence against this novel Riparian Ancestor Hypothesis detail.

The Scirtidae Fleming, 1821 has been identified as one of the earliest diverging groups Polyphagan beetles and is particularly speciose in Australia. However, very little known about origin Australian scirtids there a need for robust, well-supported phylogeny to guide genus species descriptions understand relationships among taxa. In this study we carried out phylogenetic analysis Scirtinae 1821, using DNA sequence data from ultraconserved elements (UCEs) included representative taxa New Zealand, Caledonia, South America, Africa Eurasia analysis. Bayesian analyses concatenated dataset 79 recovered four major Southern Hemisphere groupings two Australian–Eurasian groupings. Veronatus group mainly consisted genera with three representatives only distantly related each other. Relaxed molecular clock analyses, estimated age crown node Polyphaga calibration, support Gondwanan history northern groups. Our results highlight value commercially available UCEs resolving ancient Coleoptera.

Published: Dec. 5, 2022

Abstract Minute moss beetles (Hydraenidae) are one of the most speciose and widespread families aquatic Coleoptera, with an estimated 4000 extant species, found in majority habitats from coastal rock pools to mountain streams Arctic Circle Antarctic islands. Molecular phylogenetic works have improved our understanding evolutionary history megadiverse Hydraena , Limnebius Ochthebius recent years, but genera family not yet been included any analyses, particularly those which restricted Southern Hemisphere. Using a multimarker molecular matrix, sampling over 40% described species richness 75% currently recognized genera, we infer comprehensive phylogeny these predominantly Gondwanan Hydraenidae. Whilst focus on morphologically diverse, classified across all four hydraenid subfamilies, analyses suggest that may instead constitute single clade. As result findings, African genus Oomtelecopon Perkins syn.n. is shown nest within Coelometopon Janssens, New Zealand Homalaena Ordish Podaena synonymised Orchymontia Broun, South Pterosthetops Prosthetops Waterhouse, resulting Pterosthetopini being Prosthetopini Perkins.

We propose replacement name ordishi nom.n. for dilatata Ordish, 1984 (now junior homonym); altogether 39 new combinations proposed. Our Bayesian divergence times origin this ‘Gondwana group’ Africa plus Madagascar mid‐Cretaceous both vicariant dispersal processes, together extinctions, shaped biogeographic Hemisphere during Cretaceous, geographically conserved lineages.
