Ireland international D’Arcy missed out on a starting pick for Leinster's recent Heineken Cup victory against Bath but returns the side at inside centre, with Fergus McFadden shifting out to 13.
Eoin O’Malley is named on the bench, along with Andrew Conway.
David Kearney starts on the right wing after scoring a brace of tries last time out in the PRO12 against Cardiff Blues earlier this month and he forms a back three with Fionn Carr and Luke Fitzgerald.
Eoin Reddan and Ian Madigan link up at half back while up front Cian Healy starts in the front row alongside fellow Ireland players Sean Cronin and Mike Ross. Leinster will be captained by Shane Jennings.
Ulster will play two games in the space of four days, with Munster set to visit Ravenhill on Friday, 30 December, and that has prompted Brian McLaughlin to name a very weak team.
Three debutants will start in the backline: centres Chris Farrell and Michael Allen, along with fullback Peter Nelson who has been very impressive for the Ravens in their British & Irish Cup campaign so far this season.
Elsewhere in the backs, Paul Marshall will be partnered at half back by James McKinney, who will make his first start for the province after a brief substitute appearance against the Ospreys in September.
Simon Danielli returns to the team and will occupy the left wing berth, with Phoenix Academy winger Chris Cochrane lining out on the other flank.
Up front, Callum Black, who arrived in Belfast during the summer from Worcester, will make his senior Ulster debut at loosehead prop, while Academy player Ali Birch, a mainstay of the Ulster Ravens side, will make his first senior appearance at openside flanker.
Birch is joined in the back row by Robbie Diack and Neil McComb, who while more used to the second row, will don the no6 jersey.
Tim Barker and Lewis Stevenson form an experienced second row combination, while Black is joined by captain Nigel Brady, and Adam Macklin in the front row.
League leaders Leinster are unbeaten in their last eleven fixtures in all competitions since Glasgow lowered their colours at the RDS on 17 September.
Their only defeat in their last five clashes with a fellow Irish province was 9-19 to Munster in last season's final. Ulster’s most recent victory on the road to a fellow Irish province was in September 2009, when they beat Connacht.
Monday’s game is expected to sell out and Leinster have warned that no tickets will be available on the day of the game.
Leinster v Ulster in the Rabodirect Pro12 at the RDS on St Stephen’s Day, 26 December, at 5.30pm.
