“…While a sister-group relationship of Mesitiinae and Scleroderminae has been repeatedly found (Carr et al 2010: using 'Cephalonomiini' in place of Scleroderminae;de Brito et al 2022;Colombo et al 2022), morphological analyses including extinct lineages retrieve the Mesitiinae in different positions [sister-group to all extant Bethylidae but Bethylinae in Colombo et al (2020); sister-group to all extant subfamilies here]. Similarly, the Pristocerinae has been found to be sister of the Epyrinae (Carr et al 2010: using 'Epyrini' instead of Epyrinae) or [Epyrinae + Protopristocerinae] (Colombo et al, 2020; this study), but other molecular analyses found it as sister to all extant subfamilies but the Bethylinae (de Brito et al 2022;Colombo et al 2022). Finally, one major change between our cladogram and those found in the above-mentioned works is the position of the Bethylinae, as the first extant subfamily to diverge in all the contributions while it is here deeply nested within the tree.…”

“…Indeed, these morphology-based hypotheses do not fully align with molecular-based hypotheses (Carr et al 2010;de Brito et al 2022;Colombo et al 2022) and many deep relationships remain undeciphered.

The Lancepyrinae are an extinct subfamily of Bethylidae known exclusively from Cretaceous amber deposits of Lebanon, Spain, Taimyr and Myanmar. In this study, we describe and illustrate four new genera and five new species of lancepyrine wasps from the Albian of Hkamti and late Albian-early Cenomanian of Kachin (Myanmar): Azepyris delamarreigen. et sp. nov., Burmapyris ohmkuhnleisp. nov., Gwesped groehnigen. et sp. nov., Paralanceis chotardigen. et sp. nov. and Yunbayin rosseigen. et sp. nov. These taxa not only highlight the taxonomic diversity of the Lancepyrinae during the mid-Cretaceous but they also reveal the morphological disparity of the subfamily. To establish the phylogenetic relationships of these fossils and to check the monophyly of the Lancepyrinae, we add them to a pre-existing morphological matrix and perform a cladistic analysis. We retrieve the subfamily as poorly supported yet monophyletic, with the newly described taxa deeply nested in it. A key to the genera of Lancepyrinae is provided. Finally, we erect the subfamily Cretabythinaesubfam. nov. for the genera Cretabythus Evans, 1973, Holopsenelliscus Engel, 2019 and MegalopsenellaJouault et al., 2020 as no taxonomic treatment has been provided for these taxa after the transfer of HolopsenellaEngel et al., 2016 as Aculeataincertae sedis.
