Commonwealth champion 400m hurdler Dai Greene and double world champion discus thrower Aled Davies are part of Wales' athletics team for Glasgow 2014.
Team Wales originally announced a 33-strong squad, including six para-athletes.
Several debutants in the squad, include 16-year-old Swansea sprinter Hannah Brier who is part of the 4x100m relay squad.
T37 sprinter Rhys Jones and 800m runner Joe Thomas have been selected, but their inclusion is subject to fitness.
However, there is after he failed to achieve the A standard 200m selection time at the Welsh Athletics Championships in Cardiff.
And 800m runner Gareth Warburton was ruled out after being charged with anti-doping rule violations.
National performance coach for Welsh Athletics, Scott Simpson, said: "We have selected one of the largest ever athletics contingents, something that truly reflects the strength and depth of the sport in Wales at this time."
Jon Morgan, executive director at Disability Sport Wales, said: "This is a particularly talented squad of athletes who will be representing Team Wales. We very much hope they will be able to bring their experience of Paralympic, World and European championships to the fore when competing in Glasgow."
Chris Jenkins, chief executive of the Commonwealth Games Council for Wales, the organisation responsible for selecting the team, added: "There is a great mixture of experienced athletes and debutants in the team which always makes things exciting to watch."
