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. Cretaceous fossil record been tremendously enriched by discovery amber inclusions. Numerous represent all major polyphagan lineages also remaining suborders. Improved analytical methods for documenting placing extinct taxa discussed. Different factors have played role beetles. enormous number species flowering plants, timing patterns phytophagous indicate angiosperm radiation macroevolution. Moreover, evolution intimate partnerships symbionts acquisition novel genes—obtained from fungi bacteria via horizontal gene transfers—facilitated use plant material as food source key innovations plant‐feeding

Evolution, types, and distribution of flight control devices on wings and elytra in bark beetles

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Март 24, 2024

Gaining the ability to fly actively was a ground-breaking moment in insect evolution, providing an unprecedented advantage over other arthropods. Nevertheless, active flight costly innovation, requiring development of wings and muscles, provision sufficient energetic resources, complex control system. Although wings, budget insects have been intensively studied last decades, almost nothing is known regarding flight-control devices many crucial groups, especially beetles (Coleoptera). Here, we conducted phylogenetic-informed analysis flight-related mechanosensors 28 species bark (Curculionidae: Scolytinae, Platypodinae), economically ecologically important group characterized by striking differences dispersal abilities. The results indicated that beetle apparatus equipped with different functional types mechanosensors, including strain- flow-encoding sensilla. We found strong effect allometry on number while no relative wing size (a proxy investment) identified. Our study constitutes first step understanding drivers constraints evolution Coleoptera, beetles. More research, quantitative neuroanatomical should be future.

Phylogenomics and revised classification of Lymexyloidea and Tenebrionoidea (Coleoptera: Polyphaga: Cucujiformia)

Systematic Entomology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 22, 2025

Abstract Cucujiformia forms a substantial part of beetle diversity; however, relationships within this group remain unsettled. We used large‐scale phylogenomic data to investigate early splits the Tenebrionoid clade, focusing on phylogenetic positions Lymexylidae and Ripiphoridae. In concert with previous studies, we recovered Lymexyloidea as sister Tenebrionoidea, clade Ripiphoridae + Mordellidae remaining Tenebrionoidea. Based their morphology deep divergence, designate ‘mordelloid clade’ for Mordellidae. contained two major clades: Lymexylidae, subfamilies Lymexylinae Atractocerinae, Hylecoetidae sensu novo , Hylecoetinae Melittommatinae. Contrary molecular found be monophyletic, Ptilophorinae or Ripidiinae all clades. Additionally, studied phylogeny fossil tenebrionoids, establishing following new families: †Wuhuidae fam. nov ., †Bellimordellidae †Mirimordellidae . Furthermore, †Praemordellidae stat. (originally subfamily Mordellidae) were elevated family rank, †Yakutiinae subfam. proposed † Angimordella Bao et al. was transferred from Mordellinae †Apotomourinae, Primaevomordellida Reynoldsiellini Mordellini. The newly classification is summarized discussed, family‐level identification keys provided taxa in clade’. New nomenclatural changes include synonymies Mordella bimaculata Fabricius syn. tricuspidata Goeze (now Macrosiagon Hentz) Trigonodera Dejean Pelecotoides Laporte, earlier authorship Ctenidia Laporte (1833, not 1840).

Family-level diversity of Coleoptera (Insecta) from the Nanling Mountains and the Greater Bay Area, China

Zootaxa, Год журнала: 2024, Номер 5528(1), С. 17 - 37

Опубликована: Окт. 22, 2024

Coleoptera comprise 198 families and over 440,000 species to date, of which 143 35,000 are known in China. Of these, only 64 have been recorded Guangdong Province, fewer than Hong Kong. To investigate the insect diversity Guangdong, numerous specimens were collected from Nanling Mountains Greater Bay Area using various methods, 200,000 assigned families. Thus, a preliminary study beetles at family-level is carried out based on examined historical records. An updated checklist beetle increases number 111, Eupsilobiidae for first time China new species, Eidoreus haizhuensis sp. nov. described here, demonstrating importance persistent collecting with different methods diversity. Habitus images most occurring provided. And records compared detail published records, showing that more may potentially be found requiring further field work taxonomists working niche groups.

A light in the dark: a mid-Cretaceous bioluminescent firefly with specialized antennal sensory organs

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 291(2030)

Опубликована: Янв. 1, 2024

The beetle superfamily Elateroidea comprises the most biodiverse bioluminescent insects among terrestrial light-producing animals. Recent exceptional fossils from Mesozoic era and phylogenomic studies have provided valuable insights into origin evolution of bioluminescence in elateroids. However, due to fragmentary nature fossil record, early fireflies (Lampyridae), one charismatic lineages insects, remains elusive. Here, we report discovery second firefly, Flammarionella hehaikuni Cai, Ballantyne & Kundrata gen. et sp. nov., Albian/Cenomanian northern Myanmar ( ca 99 Ma). Based on available set diagnostic characters, interpret specimen as a female stem-group Luciolinae. possesses deeply impressed oval pits apices antennomeres 3–11, representing specialized sensory organs likely involved olfaction. light organ near abdominal apex resembles that found extant lucioline fireflies. growing record lampyrids provides direct evidence stunning displays were already established by late Mesozoic.

Repeated feeding guild evolution: the impact of competition on diversification

Evolutionary Journal of the Linnean Society, Год журнала: 2024, Номер 3(1)

Опубликована: Янв. 1, 2024

Abstract Adaptive zones are defined as ecological opportunities for lineages to diversify. Cucujoid beetles provide a unique system investigate adaptive zones, specifically the interplay between factors that may predict diversity and mechanisms such competition limit diversification. Using taxon-rich, time-calibrated phylogeny of cucujoid beetles, we report clade ages in conjunction with estimated major shifts feeding ecology within this group. With these ages, calculate delay time-to-colonization food resources compared extant each We uncovered pattern increased lineage novel probably devoid from other beetles. Neither resource, age nor beetle were able species groups. Our results evidence shifting resource first is strong predictor diversity.
