Abstract: We propose a generalized version of the tribimaximal (TBM) ansatz for lepton mixing, leading to a nonzero reactor angle θ13 and CP violation. The latter is characterized by two CP phases. The Dirac phase, affecting neutrino oscillations, is nearly maximal (δCP±π/2), while the Majorana phase implies narrow allowed ranges for the neutrinoless double beta decay amplitude. The solar angle θ12 lies nearly at its TBM value, while the atmospheric angle θ23 has the TBM value for a maximal δCP. Neutrino oscillation predictions can be tested in present and upcoming experiments.
