Munster-bound Tadhg Beirne is one of two uncapped players named in the Ireland squad for the summer tour of Australia.
The Scarlets man, who is due to face Leinster in Saturday's Guinness Pro14 final, has been in fine form for Scarlets and was nominated for the European Player of the Year award.
The Kildare native should make his Ireland debut in one of three Tests against the Wallabies.
Also included for the first time is Leinster out-half Ross Byrne.
The Grand Slam winners will play against Australia on 9 June in Brisbane, 16 June in Melbourne and 23 June in Sydney.
Also named in the 32-strong party is captain Rory Best, Johnny Sexton and Joey Carbery.
Leinster's Luke McGrath has been omitted, while Ulster's John Cooney and Kieran Marmion of Connacht provide back-up for Conor Murray at scrum-half.
Lock Iain Henderson and centre Robbie Henshaw, who are both currently sidelined with injury, have also been named in the squad.
Joe Schmidt said: "This has probably been the most difficult selection process for the coaching group to date.
"We sat down on Monday morning to review the last pieces of footage and to discuss the balance and combinations that we felt we might need in Australia.
"At midday we made the final decisions which included a number of very tough calls and some players are incredibly unlucky to miss out on selection.
"Over the past couple of months the national coaches have spent time in the provinces and been in communication with the provincial coaches who have done a super job in managing the players across the season.
"The coaching group are excited by the challenge that this three Test tour will present and from talking to the players we get a sense that they too are excited about going on tour and testing themselves against one of the best sides in the world in their own backyard."
