Here I present to you a generica whose name I found in the Annuario degli attori 1977: Maria Mascarielli, who was apparently always uncredited and who currently has no entry on the IMDb (2018). She has a typical "Fellini face" and indeed she appeared in many films for Fellini.
On "Annuario degli attori 1976" she's listed as Renee Lorena.
