The structure of recently discovered identical superdeformed bands in {sup 151}Tb and {sup 152}Dy, and in {sup 150}Gd and {sup 151}Tb are discussed in terms of the strong-coupling approach. Based on the experimental evidence that the superdeformed core of {sup 152}Dy is extremely insensitive to the polarization effects induced by the odd particle, the bands are shown to exhibit the presence of the pseudo SU(3) symmetry at extreme conditions of large elongations and high spins.
