Let ( M , g ) be a non-Kenmotsu ( κ , μ )′-almost Kenmotsu manifold of dimension 2 n + 1. In this paper, we prove that if the metric g of M is a *-Ricci soliton, then either M is locally isometric to the product ℍ n +1 (−4)×ℝ ⁿ or the potential vector field is strict infinitesimal contact transformation. Moreover, two concrete examples of ( κ , μ )′-almost Kenmotsu 3-manifolds admitting a Killing
