Two new features of superdeformed (SD) bands in the [ital A][approx]190 region emerge from a study of [sup 194]Hg with the Gammasphere detector array. A decrease of the dynamic moment of inertia is observed for rotational frequencies [h bar][omega][ge]0.4 MeV, confirming long standing expectations based on mean field calculations with pairing. Evidence for a small staggering in the SD transition energies is also observed, suggesting the presence of terms with fourfold symmetry in the SD Hamiltonian.
