Mimicry and secondary defense are staples among predator-prey interactions. Among insects, the stick leaf insects masters of camouflage. Nonetheless, a meager understanding their origin early mimetic evolution persists. Here, we report earliest defensive strategies insect from Middle Jurassic China, Aclistophasma echinulatum gen. et sp. nov., exquisitely preserving abdominal extensions femoral spines. The distribution these characteristics mapped onto phylogeny Phasmatodea reveals that...
Insects have evolved complex sensory systems that are important for feeding, defence and reproduction. Parasitoid wasps often spend much time effort in searching concealed hosts with the help of specialized sensilla. However, early evolution such behaviour sensilla is poorly known. We describe two fossil female wasps, †Tichostephanus kachinensis sp. nov. longus nov., from mid-Cretaceous Kachin amber. Phylogenetic analyses based on morphological data retrieved as deeply nested within...
Wingless and shorter winged stick insects are very common today, but most known extinct had fully developed wings, leading to contentious affinities among the extant groups. We report herein three male insects, assigned Pterophasmatidae fam. nov., from mid-Cretaceous Myanmar (Burmese) amber. nov. regarded as transitional taxa modern wingless based on their similar tegmina venation with Susumanioidea some body features same Phasmatodea. However, symmetric phallic organs comprising two...
Twig mimicry is common and diversified within Phasmatodea (stick leaf insects). However, the fossil record of scant, especially evidence for early evolution twig mimicry. Herein, Yang et al. describe several stick insects from Middle Jurassic (∼165 Ma) mid-Cretaceous (∼99 Ma), reconstruct transitions in thoracic morphology relating to their overall form. Based on phylogenetic relationships Phasmatodea, new findings suggest a possible evolutionary scenario phenomenon
Abstract Background Phasmatodea (stick and leaf insects) play a central role on the debate regarding wing reduction loss, its wings are putative reacquisition from secondarily wingless ancestors based solely extant species. A pivotal taxon in this respect is species-poor Timematodea, consisting of approximately 21 species, which form sister group all remaining winged or stick insects, Euphasmatodea. Results Herein, new fossils Timematodea mid-Cretaceous Kachin amber reported, with species...
Most described Mesozoic ants belong to stem groups that existed only during the Cretaceous period. Previously, earliest known crown were dated Turonian (Late Cretaceous, ca. 94-90 million years ago (Ma)) deposits found in USA, Kazakhstan, and Botswana. However, recent discovery of an alate male ant Kachin amber from Cenomanian (ca. 99 Ma), representing a new genus species,
Abstract Three new species of wasps (Hymenoptera: Vespidae) from mid-Cretaceous Myanmar (Burmese) amber, with club-shaped antennae, are assigned to Archaeovespa gen. nov. and provide morphological information for phylogenetic analyses Vespidae. Phylogenetic results suggest that has more affinities Masarinae than Protovespinae and, along Masarinae, composes the sister clade Polistinae, Eumeninae, Vespinae Stenogastrinae. New findings indicate antennal morphologies Vespidae diversified...
Abstract A new extinct insect group, Magicivena gen. nov. in Magicivenidae fam. nov., with M . sticta sp. (type species), M. elegans antennalis and sp., is reported as Insecta incertae ordinis based on four specimens from the Lower Cretaceous Yixian Formation of north‐eastern China. are characterized by special antennal structures, such each flagellomere having two lateral transverse rows setiferous pits, forewing venations a very short subcostal anterior (Sc), radial posterior (RS)...
