Barrett, O'Mahony, Keohane and Arthurs featured for Ireland in the World Sevens in Dubai in November 2013 with Doyle and Cronin travelling to the USA to make their international sevens debuts.
The squad includes three new players who have been identified as part of the IRFU's on-going talent identification programme.
The programme, which is open to the wider athletic and team sport community, offers elite athletes the opportunity to join an Olympic programme in what is a new and exciting international female sport.
Ireland have been drawn in a strong group in Pool B alongside New Zealand, England and the Netherlands.
Head Coach, Jon Skurr said: "A lot of hard work has gone in to get us to this point so far. It's a big year for Irish women's rugby, there's a lot going on and one of our jobs is to extend the player base that we've got, so that we've got more people competing, which is why our talent identification process is so important.
"We've got a number of new caps going. It's going to be tough, but I feel we're really going to progress as the season goes on as these players develop their ability to play international rugby at the top level."
