Paleobiology of beetles (Insecta: Coleoptera) from Western European Cretaceous ambers
2016Co-Authors: David Peris, Vincent Perrichot, Enrico Ruzzier, Enrique Penalver, Xavier DelclosAbstract:The whole assemblage of beetles in the Cretaceous ambers of Western Europe (Spain and France) is surveyed for the first time (Peris et al., 2016). Spanish amber (upper Albian in age) has 149 specimens of 30 families while French amber (upper Albian–Santonian in age) has 65 specimens of 16 families (Table 1). Only five families are shared by both ambers: Caridae (Fig. 3E), Ptinidae, Scraptiidae (Fig. 6C), Staphylinidae, and Trogossitidae; thus totaling 41 different families identified, mainly into Polyphaga (Table 1). This low number of shared families is surprising, considering the paleogeographic and temporal proximilty of both areas (Figs. 1-2). The sligthly ancient origin for the Spanish amber, the paleogeography (including some barriers for terrestrial biota) and the local paleohabitats are factors that may explain the dissimilarity with the French specimens.The Spanish and French ambers clearly contain, up today, the oldest representatives of the Polyphagan families: Bostrichidae (Fig. 3C), Elmidae, Eucinetidae (Fig. 4A), Histeridae (Fig. 4B), Jacobsoniidae (Fig. 4C), Leiodidae, Limnichidae (Fig. 4E), Nosodendridae (Fig. 5C), Oedemeridae, Omethidae (Fig. 5D), Phalacridae (Fig. 5E), Ripiphoridae (Fig. 6A), and Tetratomidae (Fig. 6F). Furthermore, the records for the families Bostrichidae, Elmidae, Limnichidae, Nosodendridae, Omethidae and Phalacridae are the sole record for the whole Mesozoic (Peris, 2015). This means that all these families already existed at least in the late Early Cretaceous and have persisted until now. Blakey, R.C. 2011.

The involvement of beetles in high resin production during the Cretaceous has been reconsidered after the low presence of wood-borer families in these and other Cretaceous ambers from the Tethyan realm. By contrast, most families identified currently maintain a saproxylic or detritivorous life style (Table 1). Therefore, this release of resin was influenced by other causes such as wildfires, storms or some other biological effect (Peris et al., 2016).

The earliest occurrence and remarkable stasis of the family Bostrichidae (Coleoptera: Polyphaga) in Cretaceous Charentes amber
Palaeontologia Electronica, 2014Co-Authors: David Peris, Xavier Delclos, Carmen Soriano, Vincent PerrichotAbstract:A new fossil species of auger beetle (Coleoptera: Bostrichidae), preserved in mid-Cretaceous (Albian-Cenomanian) amber from south-western France, is described as Stephanopachys vetus Peris, Delclos et Perrichot sp. n. The species is the earliest fossil bostrichid discovered to date, but is remarkably similar to Recent species of the genus Stephanopachys, supporting long morphological conservation in wood boring beetles. The specimen is fossilized in fully opaque amber and was imaged in 3D using propagation phase-contrast X-ray synchrotron microtomography. Based on the ecology of extant related species habits, it is suggested that S. vetus sp. n. was a primary succession pioneer following wildfires in mid-Cretaceous forests. The fossil record of the family is reviewed

Ancient symbiosis confers desiccation resistance to stored grain pest beetles
Molecular Ecology, 2017Co-Authors: Tobias Engl, Nadia Eberl, Theresa Krüger, Thorsten H. P. Schmidt, Rudy Plarre, Cornel Adler, Carla Gorse, Martin KaltenpothAbstract:Microbial symbionts of insects provide a range of ecological traits to their hosts that are beneficial in the context of biotic interactions. However, little is known about insect symbiont-mediated adaptation to the abiotic environment, for example, temperature and humidity. Here, we report on an ancient clade of intracellular, bacteriome-located Bacteroidetes symbionts that are associated with grain and Wood pest beetles of the phylogenetically distant families Silvanidae and Bostrichidae. In the saw-toothed grain beetle Oryzaephilus surinamensis, we demonstrate that the symbionts affect cuticle thickness, melanization and hydrocarbon profile, enhancing desiccation resistance and thereby strongly improving fitness under dry conditions. Together with earlier observations on Symbiont contributions to cuticle biosynthesis in weevils, our findings indicate that convergent acquisitions of bacterial mutualists represented key adaptations enabling diverse pest beetle groups to survive and proliferate under the low ambient humidity that characterizes dry grain storage facilities.

Composition and diversity of xylophagous and predatory beetles in Vachellia xanthophloea (Benth.) P.J.H.Hurter (Fabales: Fabaceae) at Kenyatta University and Mitaboni, Kenya
Elsevier, 2019Co-Authors: R. Kahuthia, A. Abonyo, B. ImbayiAbstract:Xylophagous beetles cause damage to Vachellia xanthophloea (Benth.) P.J.H.Hurter by burrowing and tunneling damaged or deadwood resulting in extensive frass-filled galleries. A study was conducted from 2016 to 2018 to evaluate the composition and diversity of the xylophagous beetles. Fresh infested pieces of V. xanthophloea were collected from Mitaboni and Kenyatta University (KU), Kenya, and kept in KU laboratories for adult emergence. We recorded 7,959 and 7,804 beetles in KU and Mitaboni, respectively. The families included Bostrichidae, Bothrideridae, Buprestidae, Ciidae, Cerambycidae, Cleridae, Curculionidae, Dermestidae, Histeridae, Laemophloeidae, Lyctidae, Ptinidae, Silvanidae, Staphylinidae, Tenebrionidae, Trogossitidae, and Zopheridae. Ptinidae was present in Mitaboni only, while Ciidae and Zopheridae were unique in KU. Bostrichidae was the most abundant family accounting for 28.82% and 57.27% beetles followed by Curculionidae at 15.00% and 20.46% in KU and Mitaboni, respectively. Xylion adustus (Fahraeus) (Bostrichidae) accounted for 24.73% in KU, while Sinoxylon ruficorne Fahraeus (Bostrichidae) accounted for 24.83% in Mitaboni. Species richness (S), Shannon diversity index (H), and evenness (J) were higher at Mitaboni (S=54; H=2.45; and J=0.614) than KU (S=51; H=2.33; and J=0.596). Further studies should be conducted to document and enrich knowledge on diversity and distribution of the species associated with decaying V. xanthophloea.
