  Let $V$ be a simple vertex operator superalgebra and $G$ a finite
automorphism group of $V$ containing the canonical automorphism $\sigma$ such
that $V^G$ is regular. It is proved that every irreducible $V^G$-module occurs
in an irreducible $g$-twisted $V$-module for some $g\in G$ and the irreducible
$V^G$-modules are classified. Moreover, the quantum dimensions of irreducible
$V^G$-modules are determined, a global dimension formula for $V$ in terms of
twisted modules is obtained and a super quantum Galois theory is established.
In addition, the $S$-matrix of $V^G$ is computed
