South Africa have called up Robin Peterson to their squad for the tour of Bangladesh.
Peterson replaces fellow left-arm spinner Paul Harris, who requires surgery on an abscess that will rule him out for three weeks.
"Robbie has shown excellent form in the SuperSport Series competition," said selection convener Joubert Strydom.
"He was the leading wicket-taker among South African spin bowlers with 24 wickets with the only spin bowler to do better being Imran Tahir of Pakistan and the Nashua Titans who claimed 31 dismissals.
"It is also important to maintain consistency in selection. Robbie and Johan Botha were our two spin bowlers in the South African A side that played the West Indies, so we have the same combination again.
"It is also important to have the variety offered by having a left-hander and a right-hander in our spin attack."
Peterson will leave to join the squad in Bangladesh later this week along with batsman Neil McKenzie, whose departure was delayed due to personal reasons.
South Africa are scheduled to play Tests in Dhaka (Feb 22-26) and Chittagong (Feb 29-Mar 4) followed by a three-match one-day series.
