We consider spaces with a special kind of Riemannian tensor. It is proved that they are semisymmetric spaces. These spaces are divided into three types and we investigate nontrivial geodesic mappings for each type. In particular, it is proved that if these spaces admit nontrivial geodesic mappings, then they have a constant scalar curvature.
