A new family of oegopsid cephalopods, Cycloteuthidae, is erected as a result of the elevation of Naef's subfamily Cycloteuthinae. Cycloteuthis sirventi Joubin, 1919, is redescribed based on new material from the Atlantic Ocean. A new genus, Discoteuthis, and two new species, D. discus and D. laciniosa, are described from the Atlantic Ocean. Larvae of C. sirventi and D. laciniosa are described. The distributions of the species of cycloteuthids in the Atlantic and Indian Oceans are presented. The relationships of the family, genera, and species are discussed.
