The paper is devoted to the geometry of hypersurfaces in quasi-Kählerian manifolds. Among six theorems presented in the paper, we find the ones: on inducing of a quasi-Sasakian structure to a hypersurface of a nearly-Kählerian manifold; on a locally holomorphically isometric classification of $$\eta$$-umbilical hypersurfaces in $$2n$$-dimensional complex space forms; and, in such a manifold, on a characterization of $$\eta$$-Einstein hypersurfaces among quasi-Sasakian ones.
