Abstract: We consider superstring sigma models that are based on coset superspaces G-Hin which H arises as the fixed point set of an order-4 automorphism of G. Weshow by means of twistor theory that the corresponding first-order system,consisting of the Maurer-Cartan equations and the equations of motion, arisesfrom a dimensional reduction of some generalised self-dual Yang-Mills equationsin eight dimensions. Such a relationship might help shed light on the explicitconstruction of solutions to the superstring equations including their hiddensymmetry structures and thus on the properties of their gauge theory duals.
