Les auteurs ne sont pas en accord sur la synonymie entre Conaea rapax et Antaria gracilis de Dana,1849 (description insuffisante pour Giesbrecht, 1892), alors que A. Scott (1909) considère cette forme comme un synonyme junior. Pour Heron (1977) les deux espèces sont différentes contrairement à l'opinion de Boxshall (1977 a).
