Abstract Discrete energy bands of ion fluxes, typically organized in velocity with equal separations, have been frequently observed in Jupiter’s magnetosphere either in association with Galilean moons or in regions far from their influence. Here, we focus on the latter type and propose that these bands are manifestations of bounce‐phase structuring, analogous to drift‐phase structuring responsible for the well‐known zebra‐stripe patterns. In our proposed framework, latitude‐dependent electric‐field perturbations interact with particles at different bounce phases, producing phase‐dependent energy modulations. As the particles continue to bounce at their respective bounce frequencies, which scale with velocity, these modulations naturally evolve into discrete, velocity‐ordered banded structures. We examine several potential sources of latitude‐dependent electric fields, including impulsive disturbances and wave‐related processes, and perform test‐particle simulations showing that the key observational features can be reproduced. These results support bounce‐phase structuring as a unifying interpretation of discrete bands, providing potential diagnostic perspectives on Jovian magnetospheric dynamics.
