    Let \(M\) be a hypersurface in a complex space form \(\tilde{M}(c)\). \textit{P. J. Ryan} [Colloq. Math. 26, 175--182 (1972; Zbl 0243.53028)] classified the Kähler hypersurfaces with regard to the Ricci semi-symmetric tensor \(S\), i.e., \[ (R(X,Y)S)Z = 0. \] In this paper the authors study the property of a Kähler hypersurface \(M\) whose Ricci tensor satisfies the weaker condition \[ (R(X,Y)S)Z + (R(Y,Z)S)X +(R(Z,X)S)Y = 0, \] proving that these hypersurfaces are locally symmetric.
