Abstract
We construct the manifestly Lorenz-invariant formulation of the N = 1 D = 4 massive superparticle with spinorial central charges. The model possesses from one to three κ-symmetries. The local transformations of κ-symmetry are written out. The using of index spinor for construction of the tensorial central charges is considered. The equivalence at the classical level between the massive D = 4 superparticle with one κ-symmetry and the massive D = 4 spinning particle is obtained.
