AbstractA quasi-Jacobi form for J-unitarily diagonalizable J-normal matrices is given, extending a result for normal matrices due to Malamud. The inverse eigenvalue problem for J-normal matrices satisfying certain prescribed spectral conditions is investigated. It is shown that there exists unicity in the case of pseudo-Jacobi matrices
