“…The oldest known flat wasp fossils are from the Lower Cretaceous (ca. 130 million years old), with at least twenty-two described species so far (amber only), half of which are from Myanmar amber (Azevedo et al 2018;Engel 2019;Colombo et al 2020;Jouault et al 2020Jouault and Brazidec 2021; see also Lepeco and Melo 2021 for taxonomic changes within fossil Bethylidae). Beyond this, they have been also abundant in Cenozoic Lagerstätten (ca.…”

Parasitism, a malignant form of symbiosis, wherein one partner, the parasite, derives benefits to the detriment of another, the host, is a widespread phenomenon. Parasitism sensu lato is understood here to include many phenomena, like parasitoidism, kleptoparasitism, phoresy and obligate parasitism. Insecta has many in-groups that have evolved a parasitic life-style; one of the largest in-groups of these is probably the group of Hymenoptera. Bethylidae, the group of flat wasps, is a smaller in-group of Aculeata, the group of hymenopterans with venom stings; representatives of Bethylidae are parasitic. They are more specifically larval ectoparasitoids, meaning that their immature stages are externally developing parasites that kill their host organism at pupation (end of interaction). They mostly parasitise immature representatives of Coleoptera and Lepidoptera. Female flat wasps search for a host for their progeny, paralyse it with their venom sting and then oviposit onto it. Herein we describe one of the oldest findings of parasitic interactions of parasitoid wasps with their progenies’ hosts, specifically a flat wasp female grasping and (potentially) stinging a beetle immature in Cretaceous Kachin (Myanmar) amber (ca. 100 million years old). This finding indicates that this type of parasitic interaction existed since the Cretaceous, temporally close to the earliest findings of representatives of Bethylidae.

“…With more than 90 species in seven of the eight subfamilies (no fossil Mesitiinae has been described yet), the fossil record of Bethylidae spans nearly 130 million years from the Lower Cretaceous to the Holocene (see Martynova et al, 2019; and the posterior discoveries of: Engel, 2019;Falières and Nel, 2019a, 2019b, 2019cColombo et al, 2020Colombo et al, , 2021aColombo et al, , 2021bJouault et al, 2020Colombo and Azevedo, 2021;Jouault and Brazidec, 2021;Tribull et al, 2021). Despite this relatively high richness compared to other chrysidoid lineages (e.g., Chrysididae), lots of new species are likely to be described from Cretaceous or Cenozoic deposits, particularly from the recently discovered Miocene amber of Ethiopia and China (Bouju and Perrichot, 2020;Wang et al, 2021).…”

Despite significant advances in alpha level taxonomy in the past few decades, the higher‐level phylogeny of flat wasps (Hymenoptera, Bethylidae) remains poorly explored. Herein we provide the first phylogenomic assessment of the family based on data from ultraconserved elements for 96 species in 61 genera of the family, with material from 29 countries and all biogeographic regions. Dataset cutoffs including ultraconserved element loci recovered for 50 and 70% of terminals resulted in matrices with 1513 and 451 loci, which were analysed in both parsimony and maximum likelihood frameworks. We also provide the first analyses of divergence dating for the family based on the calibration of 12 nodes. All analyses recovered the Bethylidae as a monophyletic group and estimated the origin of the family at around 143 Ma. The results suggest that all extant subfamilies had already diversified by the Late Cretaceous. All topologies suggest that Glenosema and Chilepyris form a clade separate from other Scleroderminae; owing to the morphological distinctiveness of each genus, we propose that they are accommodated in two new subfamilies, Glenoseminae subf. nov. and Chilepyrinae subf. nov. The monotypic sclerodermine genus Galodoxa was consistently recovered within Epyrinae and is transferred to the latter subfamily.
