Halfpenny, Lydiate back for Wales
The squad includes a further seven players who didn't feature for Wales on June tour to New Zealand, including the return from injury of British & Irish Lions trio Alex Cuthbert, Leigh Halfpenny and Dan Lydiate.
Cardiff Blues prop duo Rhys Gill and Scott Andrews also return to the squad along with Ospreys loosehead Nicky Smith and No.8 Dan Baker.
There are also two uncapped players in the form of Ospreys duo Sam Davies and Rory Thornton.
In the pack Gethin Jenkins, Tomas Francis and Samson Lee join the three props already named with Scott Baldwin, Kristian Dacey and Ken Owens completing the front-row contingent.
Thornton is joined by fellow regional second-rows Bradley Davies and Alun Wyn Jones along with Luke Charteris and Jake Ball.
Captain Sam Warburton, Ospreys pair James King and Justin Tipuric, Ross Moriarty and Taulupe Faletau complete the forwards named.
Gareth Davies, Rhys Webb and Lloyd Williams are named as the three scrumhalves in the squad with Gareth Anscome and Dan Biggar joining uncapped the Davies. The centres comprise of, Jonathan Davies, Tyler Morgan, Jamie Roberts and Scott Williams. Hallam Amos, George North and Liam Williams link up with the returning Cuthbert and Halfpenny across the back three.
"It is great to give the opportunity to players who are playing well for their clubs with the likes of Nicky Smith, Rhys Gill, Rory Thornton and Sam Davies coming into the squad. In addition it's great to be able to welcome back experienced players such as Dan Lydiate, Alex Cuthbert and Leigh Halfpenny, who have missed out recently with injury and that experience will be important this autumn [November].
"Taulupe is still in his rehab process and has been working closely with Bath. We hope he will be available in the later part of the campaign, but his experience will be vitally important to have around the squad.
"We know we have to start the campaign strong and have to replicate the accuracy and intensity our opponents will bring to Cardiff. We need to build on what we did in New Zealand and take it up another level for that opening match against Australia."
The squad will meet up to begin preparations for the four-Test campaign on Monday, October 24 and face Australia in their opening encounter on November 5. World Cup semifinalists Argentina are the next opponents before Japan arrive in Cardiff and the campaign is concluded against South Africa on November 26.
