Kakoselia Handlirsch, 1906 Zygadenia is an extinct genus of archostematan beetles from the Early Jurassic to Early Cretaceous.

It is considered to be a senior synonym of Notocupes by Kirejtshuk (2020),[1] but other researchers suggest to reserve the genus Zygadenia as a form taxon for isolated elytra that probably belong to the genus Notocupes, while retaining Notocupes as a valid genus for complete body fossils.

[2][3][4] Eleven species are included in the genus, after Strelnikova and Yan (2021, 2023).

[2][3] Kirejtshuk (2020) notes that the two Lower Jurassic Australian species Z. westraliensis and Z. martinae possibly merit placement in their own separate genus.
