Acarodynerus is an Australasian genus of potter wasps.
Australasia comprises Australia, New Zealand, and some neighbouring islands. It is used in a number of different contexts including geopolitically, physiographically, and ecologically where the term covers several several slightly different but related regions.
Potter wasps, the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae.
