In 1987, Romanowska and Roszkowska found an explicit description of the lattice of varieties of differential groupoids. In 2008, the author proved that the lattice of quasivarieties of differential groupoids is $Q$-universal. In the present article, we find an example of a minimal $Q$-universal variety of differential groupoids.
