We present new accretion solutions of a polytropic perfect fluid onto anf(R)-gravity de Sitter-like black hole. We consider two f(R)-gravity models andobtain finite-period cyclic flows oscillating between the event andcosmological horizons as well as semi-cyclic critical flows executing a two-waymotion from and back to the same horizon. Besides the generalizations and newsolutions presented in this work, a corrigendum to Eur. Phys. J. C (2016)76:280 is provided.
