A renormalizable neutrino mass model based on (Z2 × Z4) ⋊ Z2 (II) symmetry is proposed for the modification of the µ−τ reflection symmetry. The hierarchies of lepton masses can be naturally realized and the lepton mixing is addressed with renormalizable Yukawa couplings. The predicted intervals of the sum of neutrino mass and the Majorana effective neutrino mass are consistent with the corresponding experimental limits.
