A new class of integrable lattice systems is introduced which are the time-discretisations of the Rogoyavlensky systems. Finite-dimensional reductions of these systems are considered that give rise to integrable mappings. Furthermore, the similarity reduction is shown to lead to higher-order q-diffe
