The Pumas coach Santiago Phelan, who steered Argentina to the 2011 Rugby World Cup quarter-finals, has been given a new two-year contract.
The Pumas, third at the 2007 World Cup in France, went out in the quarter-finals to hosts and eventual champions New Zealand at the tournament.
Ranked seventh in the world, they will make their debut in a major annual competition next year when they take part in the new southern hemisphere championship with Australia, New Zealand and South Africa which is replacing the Tri-Nations.
Never before have they faced a year with 12 test matches, having had to sit by and watch the Tri-Nations and Six Nations from afar and make do with only six matches.
