Abstract In Theorem 3 of Rocha (São Paulo J Math Sci 6:365–374, 2012) the author asserts the orbit equivalence of global attractors for nonlinearities in the same lap signature class. Since, in general, the Morse-Smale property does not hold for systems corresponding to reversible nonlinearities, this assertion needs to be replaced by the less restrictive connection equivalence of global attractors.
