Understanding the origin and diversification of organisms requires a good phylogenetic estimate their age rates. This can be difficult to obtain when samples are limited fossil records disputed, as in Dictyoptera. To choose among competing hypotheses for dictyopteran suborders, we root analysis (~800 taxa, 10 kbp) within large selection outgroups calibrate datings with fossils attributed lineages clear synapomorphies. We find following topology: (mantises, (other cockroaches,...

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...

After the revision of several fossils and observations recent taxa, we propose a new interpretation wing venation pattern for ‘orthopteroid lineage’. The Orthoptera taxa previously assigned to paraphyletic group ‘Protorthoptera’ are included in common clade, Archaeorthoptera taxon nov. some closest relative groups Panorthoptera sensu These assignments based on autapomorphies patterns. A cladistic phylogenetic analysis is performed first time fossil record this group, 74 characters (131...

Abstract Two different patterns of wing venation are currently supposed to be present in each the three orders Paraneoptera. This is unlikely compared with situation other insects where only one pattern exists per order. We propose for all Paraneoptera a new and unique interpretation pattern, assuming that convex cubitus anterior gets fused common stem median radial veins at or very near base, after separation from concave posterior, re‐emerges more distally R + M stem. Thereafter, vein...

Abstract A significant portion of Mesozoic amber is fully opaque. Biological inclusions in such are invisible even after polishing, leading to potential bias paleoecological and phylogenetic studies. Until now, studies using conventional X-ray microtomography focused on translucent or semi-opaque amber. In these cases, organisms interest were visualized prior analyses. It was recently demonstrated that propagation phase contrast synchrotron imaging techniques powerful tools access opaque...

Within modern gymnosperms, conifers and Ginkgo are exclusively wind pollinated whereas many gnetaleans cycads insect pollinated. For cycads, thrips specialized pollinators. We report such a pollination mode from Early Cretaceous amber of Spain, wherein four female representing genus two species in the family Melanthripidae were covered by abundant Cycadopites pollen grains. These females bear unique ring setae interpreted as structures for grain collection, functionally equivalent to...

Amber is of great paleontological importance because it preserves a diverse array organisms and associated remains from different habitats in close to the amber-producing forests. Therefore, discovery amber inclusions important not only for tracing evolutionary history lineages with otherwise poor fossil records, but also elucidating composition, diversity, ecology terrestrial paleoecosystems. Here, we report unique find African inclusions, Cretaceous Ethiopia. Ancient arthropods belonging...

Orthoptera have been used for decades numerous evolutionary questions but several of its constituent groups, notably crickets, still suffer from a lack robust phylogenetic hypothesis. We propose the first hypothesis evolution crickets sensu lato, based on analysis 205 species, representing 88% subfamilies and 71% tribes currently listed in database Species File (OSF). reconstructed parsimony, maximum likelihood Bayesian phylogenies using fragments 18S, 28SA, 28SD, H3, 12S, 16S, cytb (~3600...

We describe and illustrate from the earliest Eocene amber of France oldest representative rhagionid modern genus Symphoromyia, under name S. eocenica sp. nov. Its mouthpart structure shows that it was hematophagous as is representatives genus, demonstrating a remarkable morphological stability for 53 Myr.

Abstract To better understand insect evolution, fossils – mainly known by their wings must be used as terminals in phylogenetic analyses. Such analyses are, however, rarely performed because of a lack consensus on the homology venation insects. Researchers do not agree with current concept exact number and identity main veins. Here, we confirm presence, which has been question since early 20th century, an independent postcubital vein (PCu vein) between cubital anal veins (29 fossil extant...

Abstract With nearly 100,000 species, the Acercaria (lice, plant lices, thrips, bugs) including number of economically important species is one most successful insect lineages. However, its phylogeny and evolution mouthparts among other issues remain debatable. Here new methods preparation permitted comprehensive anatomical description inclusions from mid-Cretaceous Burmese amber in astonishing detail. These “missing links” fossils, attributed to a order Permopsocida, provide crucial...

Based on three specimens, the first record of hawker dragonflies from Baltic amber is described in a new genus with two species: Elektrogomphaeschna peterthieli gen. et sp. nov. and E. annekeae nov.. They belong to family Gomphaeschnidae are tentatively attributed extinct subfamily Gomphaeschnaoidinae. The latter was previously only known Cretaceous fossils here shown have survived K-Pg mass extinction event. This discovery also confirms still higher diversity during Paleogene compared...

The signatories of this letter request significant changes to the common practices in palaeontology.With our present, multi-authored comment, we aim argue why these suggestions will not lead improvement both practice and ethics palaeontological research but, conversely, hamper its further development.Although disagree with most contents SVP letter, appreciate initiative discuss scientific underlying ethics.Here, consider different aspects by Rayfield et al. ( 2020) which see weaknesses dangers.
