  We examine symmetries of chiral four-dimensional vacua of Type IIB flux
compactifications with vanishing superpotential $W=0$. We find that the ${\cal
N}=1$ supersymmetric MSSM-like and Pati-Salam vacua possess enhanced discrete
symmetries in the effective action below the mass scale of stabilized complex
structure moduli and dilaton. Furthermore, a generation number of
quarks/leptons is small on these vacua where the flavor, CP and metaplectic
modular symmetries are described in the framework of eclectic flavor symmetry.
