Didier Drogba, who participates in his fourth successive continental championship, leads the 25-man squad that includes Chelsea team mate Salomon Kalou and newly crowned African Footballer of the Year Yaya Toure.
Romaric, who played in all three matches for the Ivorians at the World Cup finals in South Africa 18 months ago, failed to make the cut when the squad was announced at an Abidjan news conference.
Instead coach Francois Zahoui selected uncapped 28-year-old Marco Ne from Russian club Kuban Krasnodar.
A total of 17 of the 23 players from the last World Cup are retained for the Nations Cup, giving the Elephants an air of consistency.
Two players will be cut from the squad by the January 11 deadline for all 16 participants at the tournament in Equatorial Guinea and Gabon to name final selections for the three-week event, which starts on January 21.
The Ivorians are among the pre-tournament favourites and face Angola, Burkina Faso and Sudan in their opening round group.
