“…Our age estimates are supported by fossil studies across the wider arthropods, e.g. the crown Coleoptera + Strepsiptera fossil Adiphlebia dated at 306.9 Mya, which then becomes the maximum (stem) age of Coleoptera [ 33 ], and also fits well with the beetle fossil record [ 30 , 34 , 35 ]. We verified the major branching events by mapping 19 fossils used as calibration points by Touissant et al [ 30 ] (Fig.…”

Genome sequencing of Rhinorhipus Lawrence exposes an early branch of the Coleoptera

BackgroundRhinorhipidae Lawrence, 1988 is an enigmatic beetle family represented by a single species, Rhinorhipus tamborinensis Lawrence, 1988, from Australia, with poorly established affinities near the superfamily Elateroidea (click beetles, soldier beetles and fireflies) or the more inclusive series (infraorder) Elateriformia. Its evolutionary position may inform the basal relationships of the suborder Polyphaga, the largest clade of Coleoptera.ResultsWe analyzed four densely sampled DNA datasets of major coleopteran lineages for mitogenomes, rRNA genes and single copy nuclear genes. Additionally, genome sequencing was used for incorporation of R. tamborinensis into a set of 4220 orthologs for 24 terminals representing 12 polyphagan superfamilies. Topologies differed to various degrees, but all consistently refute the proposed placement of Rhinorhipidae in Elateroidea and instead indicate either sister relationships with other Elateriformia, frequently together with Nosodendridae, another divergent small family hitherto placed in Derodontoidea, or in an isolated position among the deepest lineages of Polyphaga. The phylogenomic analyses recovered Rhinorhipus in a sister position to all other Elateriformia composed of five superfamilies. Therefore, we erect the new superfamily Rhinorhipoidea Lawrence, 1988, stat. Nov., with the type-family Rhinorhipidae. The origins of the Rhinorhipidae were dated to the Upper Triassic/Lower Jurassic at the very early phase of polyphagan diversification.ConclusionsThus, Rhinorhipidae adds another example to several recently recognized ancient relict lineages which are interspersed within contemporaneous hugely species-rich lineages of Coleoptera.Electronic supplementary materialThe online version of this article (10.1186/s12983-018-0262-0) contains supplementary material, which is available to authorized users.

“…et al ., 2015). So far, more than one million extant pterygotes have been described, and the fossil record provides evidence that these organisms played a key role in virtually all terrestrial ecosystems since the late Paleozoic (Grimaldi & Engel, 2005; Labandeira, 2018). Pterygote diversity is heavily skewed phylogenetically towards Holometabola (wasps, bees, ants, beetles, moths, butterflies, flies), which roughly comprise 90% of their diversity (Grimaldi & Engel, 2005; Peters et al ., 2014).…”

Fossils sometimes show unusual morphological features absent in living organisms, making it difficult to reconstruct both their affinity and their function. We describe here a new lacewing larva, Ankyloleon caudatus gen. et sp.n. (Neuroptera) from the Cretaceous amber of Myanmar, characterized by an abdomen unique among insects, with ‘tail‐like’ terminal segments bearing a ventral pair of vesicles. Phase‐contrast X‐ray microtomography reveals that these structures were dense and equipped with a median duct, suggesting that they were likely pygopods used for locomotion, holding the position through adhesive secretions. Our phylogenetic analyses, combining genomic and morphological data from both living and fossil lacewings, proved critical to placing Ankyloleon gen.n. on the lacewing tree of life as an early representative of the antlion clade, Myrmeleontiformia. These results corroborate the view that derived myrmeleontiform lacewings ‘experimented’ with unusual combinations of features and specializations during their evolutionary history, some of which are now lost.

“…3 in 4 ) generally was made possible by modifying pre-existing structural adaptations with gymnosperms (direct or indirectly), and by evolution of novel structures connected with speciation events involving angiosperms 42 . Nevertheless, familylevel insect diversity seems not to have increased during the global Cretaceous gymnosperm-to-angiosperm transition 12,14,18,43 , at least in most of the groups 20 . Some data show a slight decline of family-level insect diversity into the Late Cretaceous 13,19 .…”

The monospecific family Mysteriomorphidae was recently described based on two fossil specimens from the Late Cretaceous Kachin amber of northern Myanmar. The family was placed in Elateriformia incertae sedis without a clear list of characters that define it either in Elateroidea or in Byrrhoidea. We report here four additional adult specimens of the same lineage, one of which was described using a successful reconstruction from a CT-scan analysis to better observe some characters. The new specimens enabled us to considerably improve the diagnosis of Mysteriomorphidae. The family is definitively placed in Elateroidea, and we hypothesize its close relationship with Elateridae. Similarly, there are other fossil families of beetles that are exclusively described from Cretaceous ambers. These lineages may have been evolutionarily replaced by the ecological revolution launched by angiosperms that introduced new co-associations with taxa. These data indicate a macroevolutionary pattern of replacement that could be extended to other insect groups.
