### Hymenopteran Research

* Guo et al. (2021) report the discovery of two queen ant specimens from Burmese amber, belonging to the species Haidomyrmex cerberus and including the first known alate queen in Haidomyrmex.
* Cooccurrence of ants belonging to extant Holarctic genus Lasius and a tropical weaver ant in the same piece of amber is reported from the Bitterfeld amber (Germany) by Radchenko & Perkovsky (2021).
* Original claims that both Melittosphex burmensis and Discoscapa apicula were primitive bees have been rejected by Rosa & Melo, who instead consider the former to be an aculeate wasp of uncertain affinity, and the latter to belong within the crabronid wasp subfamily Crabroninae, a lineage not directly related to bees.
