We develop N = 4 d = 4 bi-harmonic superspace and use it to derive a novel form for the low-energy effective action in N = 4 super Yang-Mills theory. We solve the N = 4 supergauge constraints in this superspace in terms of analytic superfields. Using these superfields, we construct a simple functional that respects N = 4 supersymmetry and scale invariance. In components, it reproduces all on-shell terms in the four-derivative part of the N = 4 SYM effective action; in particular, the F-4/X-4 and Wess-Zumino terms. The latter comes out in a novel SO(3)xSO(3)-invariant form.
