Contepomi, Roncero bring experience to Pumas
The veteran pair were part of the Argentina side that finished third at the 2007 World Cup but are close to international retirement and unlikely to be in the squad when the Pumas debut in The Rugby Championship in August.
Centre Contepomi will captain what is effectively a second-string side in the three Tests, with Argentina also hosting France the following two Saturdays.
Coach Santiago Phelan, who named the side on Tuesday, has reserved his elite players for The Rugby Championship, the former southern hemisphere Tri-Nations tournament now expanded to include Argentina.
Versatile back and place-kicker Contepomi is a veteran of four World Cups and his Stade Francais team-mate and prop Roncero has played in three. The June squad includes six other players with World Cup experience.
Phelan recently named 24 Europe-based players for The Rugby Championship, with Racing Metro fly-half Juan Martin Hernandez back from injury after missing last year's World Cup in New Zealand.
He will add six players from the party playing the June Tests to that squad as Argentina face 12 international matches for the first time in a year, having previously usually had only six in the June and November Test windows.
Argentina make their debut in The Rugby Championship away to South Africa on August 18.
