Caligus uranoscopi Vaissière, 1955 (Copepoda, Caligidae) is redescribed based on specimens collected from the gill arches of red mullet, Mullus barbatus barbatus L., 1758, caught off the Algerian coast. Caligus uranoscopi is reported for the first time from the east coast of Algeria and M. barbatus barbatus is a newly recorded host for this parasite. The parasite is uncommon and may be restricted to Algerian coasts. Some remarks are given on the species of Caligidae known from Algeria.
