ASA said its women’s 4x400m relay team had been invited to compete.
The federation first said three athletes were added to the world championship squad of 23‚ and then in the afternoon upped that to four when Zoe Engler was named alongside Justine Palframan‚ Gena Lofstrand and Ariane Nel.
They will team up with Semenya and 400m hurdler Wenda Nel for the relay.
Of the remaining 20 athletes‚ ASA had picked only five on discretion‚ although that increases to six with the addition Palframan‚ who will now get to compete in the 200m after all.
Appeals by the other excluded athletes failed.

She will get two fulls days off before the 800m heats on August 10‚ with the semifinals the following day and the final on August 13.
Semenya is ranked No1 in the world in the 800m‚ and her 4min 01.99sec 1500m personal best from last year ranked her 14th in 2016. However‚ that time would have earned her gold at the Rio Olympics.
