Based on a kind of new Lie superalgebras, we proposed a scheme for constructing nonlinear super integrable couplings. Super trace identity over the corresponding loop superalgebras is used to furnish the super Hamiltonian structures for the resulting nonlinear super integrable couplings. We illustrate the application of the scheme by means of an enlarged super Ablowitz-Kaup-Newell-Segur (AKNS) matrix spectral problem and present a nonlinear super integrable Hamiltonian couplings for the super AKNS hierarchy.
