We demonstrate that the abundance of halos in cosmologies with massless and massive neutrinos from PINOCCHIO matches very well the outcome of simulations, and point out that PINOCCHIO can reproduce the $\Omega_\nu-\sigma_8$ degeneracy that affects the halo mass function.

In Fourier space and using 3LPT for halo displacements, the halo power spectrum is recovered to within 10 per cent up to $k_{max}\sim0. 5\ h/$Mpc.

We find that, in a massive neutrino cosmology, our correction to the halo mass function produces a shift in the $\sigma_8(\Omega_{\rm m}/0. 27)^\gamma$ relation which can be quantified as $\Delta \gamma \sim 0. 05$ and $\Delta \gamma \sim 0. 14$ assuming one ($N_\nu=1$) or three ($N_\nu=3$) degenerate massive neutrino, respectively.
