Given an integer

$n\ge 2$ and a real number

$c$, a complex space form

${M}_{n}\left(c\right)$ is a complex

$n$-dimensional Kaehler manifold of constant holomorphic curvature

$c$. In 1986, considering an appropriate integrable

$2n-2$-dimensional distribution

$D$,

*M. Kimura* [Trans. Am. Math. Soc. 296, 137–149 (1986;

Zbl 0597.53021)] gave a construction of a ruled real hypersurface

$M$ which is foliated by Einstein complex hypersurfaces in

${M}_{n}\left(c\right)$. Such a manifold

$M$ with the given distribution

$D$ is called an Einstein ruled real hypersurface. In the paper under review, the author generalizes that notion by introducing a pseudo-Einstein ruled real hypersurface defined as a ruled real hypersurface

$M$ which is foliated by pseudo-Einstein complex hypersurfaces of

${M}_{n}\left(c\right)$. Some examples illustrate his definition. Then, he gives a new characterization of this kind of pseudo-Einstein ruled real hypersurfaces in terms of the Ricci tensor and some integrability condition defined on a distribution orthogonal to the structure vector field in

${M}_{n}\left(c\right)$.
