Query: Two-Higgs-Doublet Models with a Flavored $\mathbb{Z}_2$   Two Higgs-doublet models usually consider an ad-hoc $\mathbb{Z}_2$ discrete
symmetry to avoid flavor changing neutral currents. We consider a new class of
two Higgs-doublet models where $\mathbb{Z}_2$ is enlarged to the symmetry group
${\cal{F}}\rtimes \mathbb{Z}_2$, i.e. an inner semi-direct product of a
discrete symmetry group ${\cal{F}}$ and $\mathbb{Z}_2$. In such a scenario the
symmetry constrains the Yukawa interactions but goes unnoticed by the scalar
sector. In the most minimal scenario, $\mathbb{Z}_3 \rtimes \mathbb{Z}_2 =
D_3$, flavor changing neutral currents mediated by scalars are absent at tree
and one-loop level, while at the same time predictions to quark and lepton
mixing are obtained, namely a trivial CKM matrix and a PMNS matrix (upon
introduction of three heavy right-handed neutrinos) containing maximal
atmospheric mixing. Small extensions allow to fully reproduce mixing
parameters, including cobimaximal mixing in the lepton sector (maximal
atmospheric mixing and a maximal $CP$ phase).
