🐝Australian #bee Leioproctus idiotropoptera, once unplaced and later given its own genus (Packercolletes), is now reclassified as an atypical Leioproctus (Colletellus), with Packercolletes sunk as a new synonym of that subgenus: doi.org/10.3897/jhr....
A note on the subgeneric placement of Leioproctus idiotropoptera Packer, 2006 (Hymenoptera, Colletidae, Neopasiphaeinae)
When it was described, the Australian bee Leioproctus idiotropoptera Packer, 2006 could not be placed to subgenus. Since then, several subgenera of Leioproctus Smith, 1853 from that region have been r...

#Genomic study resolves the mysterious #wasp genus Philoverdance. It belongs within Philotrypesis. Digging deeper reveals 5 species (4 new!) of non-pollinating fig wasps tied to Ficus tinctoria, splitting into western and eastern clades that mirror their host plant's own subspecies.
Testing the generic status of Philoverdance and revising the Philotrypesis ravii species group (Otitesellini, Pteromalidae) associated with Ficus tinctoria (Moraceae)
Philotrypesis Förster is one of the most species-rich genera of non-pollinating fig wasps associated with Old World fig trees (Moraceae, Ficus). Philoverdance Priyadarsanan was initially established t...

Great talk from Seraina Klopfstein at #BioSyst2026: "Morphology is dead - long live morphology!" Using simulations, she showed total-evidence dating is remarkably robust to violations in morphological evolution models - even with few characters. She's also a co-author in our journal:
Darwin wasps (Hymenoptera, Ichneumonidae) in Lower Eocene amber from the Paris basin
Despite their ecological importance, Darwin wasps (Ichneumonidae) are among the most poorly studied groups of organisms. It is therefore not surprising that their fossil record is even more poorly und...

Study on Pemphredon lethifer, an aphid-hunting digger wasp with biocontrol potential: nesting preferences depend on twig pith diameter. Wasps favoured larger diameters (6.5-8.5mm ideal for female offspring). Findings could help design better nest boxes to support this species doi.org/10.3897/jhr....
