    The spectrum of the ss¯ mesons is studied performing a phenomenological analysis of the Regge trajectories defined for the excitation energies. For the ϕ(33S1) state the mass M(ϕ(3 S)) = 2100 (20) MeV and the leptonic width Γee(ϕ(3 S)) = 0.27 (2) keV are obtained, while the mass of the 23D1 state, M(ϕ(23D1))=2180(5) MeV, appears to be in agreement with the mass of the ϕ(2170) resonance, and its leptonic width, Γee(23D1)=0.20±0.10 keV, has a large theoretical uncertainty, depending on the parameters of the flattened confining potential.
