“…Evidence for the extinction of this beetle lineage includes the extinction of most beetle lineages arising from ecological devastation at the Permian–Triassic boundary 8 , 24 , 42 , 46 , reflected in the narrow diversity bottleneck of family-level beetle lineages at this event 47 , and also is consistent with phylogenetic studies 42 , and a major Triassic–Jurassic time gap of simple and unelaborated wood borings 12 , 13 . This distinctive life habit re-evolved later during the Early Cretaceous 48 by bark beetles 15 , 42 . The demise of this unique wood-boring association among ancient conifers, fungi, beetles and other arthropods represent the beginnings of a food web centred in a closed, woody micro-environment that was soon extinguished but originated anew and expanded during the later Mesozoic 49 .…”

Late Permian wood-borings reveal an intricate network of ecological relationships

Beetles are the most diverse group of macroscopic organisms since the mid-Mesozoic. Much of beetle speciosity is attributable to myriad life habits, particularly diverse-feeding strategies involving interactions with plant substrates, such as wood. However, the life habits and early evolution of wood-boring beetles remain shrouded in mystery from a limited fossil record. Here we report new material from the upper Permian (Changhsingian Stage, ca. 254–252 million-years ago) of China documenting a microcosm of ecological associations involving a polyphagan wood-borer consuming cambial and wood tissues of the conifer Ningxiaites specialis. This earliest evidence for a component community of several trophically interacting taxa is frozen in time by exceptional preservation. The combination of an entry tunnel through bark, a cambium mother gallery, and up to 11 eggs placed in lateral niches—from which emerge multi-instar larval tunnels that consume cambium, wood and bark—is ecologically convergent with Early Cretaceous bark-beetle borings 120 million-years later.

Insect fossils bear important information about the evolutionary history of the group. The fossil record of Elateridae, a large cosmopolitan beetle family, has been greatly understudied and the available data are often replete with ambiguity and uncertainty. The research of Elateridae evolution cannot be done without solid genus-group name concepts. In this study we provide an updated comprehensive summary of the fossil genera in Elateridae, including their systematic placement and information on the type species, gender, number of species, age range, and relevant bibliography. We list seven valid fossil genera in Agrypninae, one in Cardiophorinae, two in Dendrometrinae, five in Elaterinae, two in Negastriinae, one in Omalisinae, one in Pityobiinae, and 36 in Protagrypninae. Additional 19 genera are tentatively classified as Elateridae incertae sedis, and their placements are discussed. Further, we move genera Babuskaya Martins-Neto & Gallego, 2009, Cardiosyne Martins-Neto & Gallego, 2006, Fengningia Hong, 1984 and Gemelina Martins-Neto & Gallego, 2006 from Elateridae to Coleoptera incertae sedis. We also discuss the genera previously placed in Elateridae, which are currently not included in the family. The data on the fossil generic diversity suggest that Elateridae originated in the Triassic and rapidly diversified and became comparatively abundant through the Jurassic. We call for further research on the fossil Elateridae from various deposits in order to increase our knowledge on the origin, evolution, and palaeodiversity of the group.

“…After these actions, the only remaining fossil flatids are: a nymph mentioned from the Miocene Mexican amber by Fennah (1963) venAtionAl FeAtures oF Priscoflata n. gen. Flatidae belong to the informal group of the Fulgoromorpha named "higher Fulgoroidea". These are characterized by relatively wide tegmina, with distinct costal area and rich pattern of longitudinal and transverse veins.…”

A new genus and species of Flatidae planthoppers, Priscoflata subvexa n. gen., n. sp., is described here on the basis of tegmen from the Paleocene of Northern Tibet. The tegminal features of this fossil and its importance for classification and phylogenetic studies within Flatidae are given. The comparison of this fossil and other extant and extinct flatids, its systematic position, its biogeographic and evolutionary significance are discussed. "Ormenis" devincta Cockerell, 1926 from the Eocene of Argentina is placed in Fulgoroidea incertae sedis. résumé Découverte d'un Flatidae (Hemiptera : Fulgoromorpha) dans le Paléocène du nord du Tibet et ses importances taxonomique et biogéographique. Un nouveau genre et une nouvelle espèce de Flatidae, Priscoflata subvexa n. gen., n. sp., sont décrits ici, sur la base d'un tegmen du Paléocene du Nord du Tibet. Les caractéristiques de la nervation tegminale de ce fossile, son importance pour la classification et l'étude phylogénétique des Flatidae sont données. La comparaison de ce fossile avec d'autres Flatidae fossiles et actuels, sa position systématique, sa biogéographie et son importance évolutive sont discutées. « Ormenis » devincta Cockerell, 1926 de l'Éocène de l'Argentine est placé dans les Fulgoroidea en position incertaine.
