The morphology distribution (using the ZEST+ code) of the 233 AGN host-galaxies on the (U − V) colour-mass diagram. We also plotted the 22 sources without morphological information. The (U − V) color and stellar masses are computed using the SED-fitting code. We overplot the contours of about 8700 galaxies in zCOSMOS (colours and stellar masses from Hyperz). The morphology classification is labeled as follow: elliptical (Ell), S0, bulge-dominated galaxy (BD), intermediate-bulge galaxy (IB), disk-dominated galaxy (DD), irregular (Irr), Compact, possible mergers (PM) and unresolved compact (UC). The red dashed line represents the red sequence cut defined by Borch et al. (2006), while the green short dashed line defines an approximate green valley region, both lines are calculated at redshift  ~0.76, which is the average redshift of the main type-2 sample.
