  We consider a Deligne-Mumford stack $X$ which is the quotient of an affine
scheme $\operatorname{Spec}A$ by the action of a finite group $G$. If the ring
$A$ is regular, the Balmer spectrum of the tensor triangulated category of
perfect complexes on $X$ is homeomorphic to the space of homogeneous prime
ideals in the group cohomology ring $H^*(G,A)$.
