With the Dutchman's future at the club still undecided, new boss Tim Sherwood has handed the armband to Fabian Delph.
Vlaar, 30, has endured a frustrating season at Villa Park since returning from his successful World Cup campaign, making just 19 total appearances after missing lark chunks of time with calf and knee injuries.
Delph was handed the armband during his most recent six-game absence but has since kept it following the Dutchman’s return, due in part to the fact that the latter's contract is up in the summer.
The experienced centre-back had held the honour of leading Villa out since being named Stiliyan Petrov’s permanent success in September 2012, just weeks after arriving from Feyenoord, and admits that he was somewhat disappointed to lose the role.
However, with his future in the West Midlands still undecided, he concedes that Delph, who in contrast has penned a new deal until 2019, is a more than suitable replacement.
"I would still have liked to do the job but it doesn't make a difference to me,” he told the newspaper. “I haven't been fit for most of the season which has been frustrating because I want to play and I want to play well. I want to be important for the team.
"When I came back into the team Fabian was captain, and that's no problem," he added. "I think Fabian has developed as a leader of the team. He's ready for it now; you can see that on the pitch and you can see it off the pitch.
"He has grown as a leader and he's the right person for the job. But it's not about me or about Fabian being captain. It's about the team."
Despite stripping him of the armband, manager Tim Sherwood has stressed in recent weeks that he is keen to tie Vlaar down to a new long-term deal but has added that talks over an extension will not take place until the end of the season.
“If there’s a contract decision to be made, whether he stays at this club or joins somewhere else, we’re going to make an adult decision,” said the Villa boss. “Ron is a man of a lot of experience now and I’m sure we will have a quite honest and frank decision to make.”
