Abstract
A clone C is essentially minimal if it contains an essential nonidempotent operation and every proper subclone of C is essentially unary. For a finite universe we determine all essentially minimal clones generated by groupoids of a certain type by means of four varieties and a family of varieties. We narrow the essentially minimal clones generated by groupoids of another type into three families.
