A new species of the genus Kimseya, K. saudica, has been described from Saudi Arabia’s Ibex Protected Area. It differs from K. boharti in body sculpture, hind wing shape, and measurements. DNA data included. Read more: doi.org/10.3897/jhr.... #taxonomy #newspecies #wasp

🥑 The first confirmed host association between the parasitoid wasp Lopheucoila mexicana and the lance #fly Neosilba batesi in avocado crops has been documented in Michoacán, Mexico. Curious to find out more? Read the full study here: doi.org/10.3897/jhr.99.195208

For Africa's Acropimpla Darwin #wasps, only females were known, and only from the east. Malaise traps in Uganda and Côte d'Ivoire have now revealed the first males and the genus's first record in West Africa. Read more: doi.org/10.3897/BDJ....

🧬 A comprehensive DNA barcoding study of Chinese parasitoid wasps has revealed diversity among encyrtid species that attack psyllids, with molecular analysis identifying 32 distinct species previously difficult to distinguish through morphology alone. Full study: doi.org/10.3897/jhr.99.202665

More on this tomorrow or the day after, but do take a sneak peek already now! This was fun to write!

🐝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....

Two new #parasitoid #wasp species have been described from the Nearctic region: Eubazus (Aliolus) confragosus and Eubazus (Aliolus) rhyssoeubazus (Braconidae, Brachistinae). Full study: doi.org/10.3897/jhr....

🐝 New study on Brachycyrtus #wasps expands distribution records across the Neotropics & Afrotropics, describes 2 new species, reports previously unknown males for 2 others, and synonymises B. zani with B. xorix, plus updated ID keys for all known #species. Full study: doi.org/10.3897/jhr....

#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.

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:

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....
