Zaha appealed against the extra punishment, which came after he sarcastically applauded referee Andre Marriner following his dismissal, despite accepting a charge of improper conduct.
The Ivory Coast international missed Palace's win over Fulham before returning against West Ham, but will now serve an additional one-match suspension after his appeal was rejected by an independent regulatory commission, and a £10,000 ($13,000, 11,000 euros) fine upheld.
"Wilfried Zaha will be suspended for Crystal Palace's game against Doncaster Rovers in the Emirates FA Cup on Sunday (17 February 2019)," said an FA statement.
"The forward accepted a charge of improper conduct, which followed his behaviour after a second-half dismissal during the Premier League game against Southampton on 30 January 2019, but subsequently appealed against a one match suspension and £10,000 fine."
