The four newcomers are Andrea Masi, Matteo Mazzantini, Fabio Ongaro and Andrea Lo Cicero, who have all been playing with the A team.
Talismanic fly-half Diego Dominguez, who picked up an injury in the 37-13 defeat by Ireland at the Stadio Flaminio last weekend, is not included in the party but could be a late addition.
In his absence Ramiro Pez, like Dominguez born in the Argentinian city of Cordoba, will take over goalkicking duties.

Mauro Bergamasco, D Dallan, A Troncon (capt), G Raineri, P Vaccari, Mirco Bergamasco, R Pez, M Mazzantini, A Masi, G Peens, C Stoica, R Martinez, F Ongaro, S Palmer, L Castrogiovanni, G De Carli, A De Rossi, M Bortolami, C Bezzi, A Persico, M Phillips, M Giacheri, C Festuccia, A Lo Cicero.
