Munster back row Alex Kendellen has been named as captain of a 34-man Ireland for Under-20 Six Nations Championship in Cardiff, one of just four players from the province in the group.
Alex Soroka and Tim Corkery, who both recently made their senior Leinster debuts, are two of six players involved at this age-grade for a second season, alongside Ulster duo Conor McKee and Ben Moxham, Connacht's Cathal Forde and Ben Murphy of Leinster.
Ireland's opening fixture is against Scotland at Cardiff Arms Park on Saturday 19 June.
There are 12 Leinster, 10 Ulster, six Connacht and four from Munster in the squad, as well as two England-based players.
Head coach Murphy, who is assisted by Denis Leamy and Colm Tucker, said: "We have been working hard for a number of weeks and it's an exciting time for these young players, who have the honour of representing the wider group in Cardiff.
"It has been a challenging year but the players have come in, worked hard and bonded well, and I have been impressed by their work-rate, commitment and application. Now our focus turns to performance and Saturday's opening game against Scotland, which we know will be a big challenge first up.
"We are looking forward to the opportunities over the coming weeks and are excited by the prospect of an Ireland U20s team returning to Six Nations action."
