  Two-loop contributions to the muon (g-2) from fermion/sfermion loops in the
MSSM are presented, and an overview of the full MSSM prediction for (g-2) is
given with emphasis on the behaviour in scenarios which are compatible with LHC
data, including scenarios with large mass splittings. Compared to all
previously known two-loop contributions, the fermion/sfermion-loop
contributions can yield the largest numerical results. The new contributions
contain the important universal quantities \Delta\alpha\ and \Delta\rho, and
for large sfermion masses the contributions are non-decoupling and
logarithmically enhanced. We find up to 15% (30%) corrections for sfermion
masses in the 20 TeV (1000 TeV) range.
