Mark Lewis-Francis has not been selected for the 100m at the World Championships, starting on 27 August.
But the 28-year-old, disqualified for a false start in the 100m final at the recent UK trials, has been selected in the 4x100m relay team in South Korea.
The individual 100m spots went to Dwain Chambers, Harry Aikines-Aryeetey and Marlon Devonish.
UK Athletics coach Charles van Commenee said: "This team has been selected to give us the best possible results."
World and European heptathlon champion Jessica Ennis, Phillips Idowu, who holds both titles in the triple jump, European 5,000m and 10,000m champion Mo Farah and Dai Greene, the European and Commonwealth 400m hurdles champion, will lead the British charge for medals in Daegu.
But there was no place for Michael Bingham (400m), Chris Thompson (10,000m) or Rhys Williams (400m hurdles).
"I am looking to see an improvement from two years ago in Berlin, where we recorded six medals and 20 top eight finishes," added Van Commenee.
"It is important to remember there is work to do before London 2012 and Daegu is another stop on the journey to make our athletes run faster, jump higher and throw further.
"The aim in Daegu is to get more athletes within touching distance of the podium and these World Championships are ideal preparation for what the athletes will encounter next summer and beyond."
Welshman Christian Malcolm will captain the 67-strong squad. The 32-year-old, who first wore a British vest 15 years ago, was delighted to have been handed the honour.
"I can't believe it. It is a proud moment in any sport to captain your country," said the sprinter, who will be competing in the 200m.
