Abstract	It is known that the class $${\fancyscript{A}}$$ of aperiodic monoids with central idempotents contains precisely two finitely generated, almost Cross subvarieties. The present article exhibits the first example of a non-finitely generated, almost Cross subvariety of $${\fancyscript{A}}$$ and verifies that it is in fact unique. Consequently, the class $${\fancyscript{A}}$$ contains precisely three almost Cross subvarieties.
