Bath Rugby summer signing Horacio Agulla is amongst those named for Argentina's historic first match in the Rugby Championship against South Africa in Cape Town on Saturday.
Juan Martin Fernandez Lobbe will skipper the side from No.8 with Racing Metro's Alvaro Galindo packing down alongside Tucuman's Julio Farias Cabello in the back-row. The second-row sees Toulouse's Patricio Albacete lining up alongside Biarritz's Manuel Carizza and the front-row is formed by Juan Figallo, Eusebio Guinazu and veteran prop Rodrigo Roncero.
In the backs, fly-half Juan Martin Hernandez starts his first Test appearance in three years for the Pumas, with Nicolas Vergallo alongside him at half-back. Agulla starts alongside Exeter's Gonzalo Camacho on the wings with Biarritz's Marcelo Bosch and Montpellier's Santiago Fernandez in the centres. Lucas Gonzalez Amorosino gets the nod at fullback.
It will be Roncero's 50th Test and on the announcement of the team he said: "It really is amazing to be part of the group of 26 players that are here in South Africa and it is a great honour to play in the Rugby Championship. We are aware that, in turn, we have a great responsibility but we must also enjoy the occasion.
"Two years ago this was impossible, but now we are here. We know it will be very hard but we feel great about being able to play in the tournament."
