  We propose an $A_4$ extension of the Standard Model with a Lepton Quarticity
symmetry correlating dark matter stability with the Dirac nature of neutrinos.
The flavor symmetry predicts (i) a generalized bottom-tau mass relation
involving all families, (ii) small neutrino masses are induced a la seesaw,
(iii) CP must be significantly violated in neutrino oscillations, (iv) the
atmospheric angle $\theta_{23}$ lies in the second octant, and (v) only the
normal neutrino mass ordering is realized.
