We introduce and study a new class of GMSB models with messenger-matter Yukawa couplings, where both the messenger-matter and the ordinary Yukawa couplings are controlled by an Abelian flavor symmetry. We derive the most general expressions for the soft terms of these models at the messenger scale and calculate the lepton sector spectra of several distinct choices of model parameters. We show that one can obtain viable models with generation-dependent slepton spectra, including mass splittings between the selectron and the smuon, and inter-generation mixings that may be observed at the LHC.
