World Cynipoidea (Hymenoptera): A Key to Higher-Level Groups
Matthew L Buffington, Mattias Forshage, Johan Liljeblad, Chang-Ti Tang, Simon van Noort, World Cynipoidea (Hymenoptera): A Key to Higher-Level Groups, Insect Systematics and Diversity, Volume 4, Issue 4, July 2020, 1, https://doi.org/10.1093/isd/ixaa003

While much has been learned regarding the phylogeny and evolution of cynipoid wasps, clearly illustrated diagnostic tools and identification keys have remained stagnant. So too, where keys do exist, they are often to genus or species, and there are no user-friendly keys to groups such as tribes, subfamilies, or families. This state of affairs leaves a knowledge gap for non-specialists and slows future research on the group.
