    •Bent functions have important applications in cryptography, coding and combinatorics.•Bent functions from the Partial Spreads class and their duals have the same form.•An answer to an open problem of Mesnager is from the Partial Spreads class. In 2014, Mesnager proposed two open problems in 4 on the construction of bent functions. One problem has been settled by Tang et al. in 2017. However, the other is still outstanding, which is solved in this letter by considering a class of PS− vectorial bent functions.
