Résumé : A redescription is given for the 1-tentacled Anthomedusa Paragotoea bathybia from new specimens collected in the Weddell Sea. The comparative study of the previous descriptions of this species permitted to define a new diagnosis for the genus which has been ascribed to the family Corymorphidae. The family Paragotoeidae Ralph, where P. bathybia was formerly included, is supressed. The 4-tentacled reconstructed stage considered by Ralph (1959) as the adult stage of P. bathybia is a new species placed in a new genus: Tetraralphia hypothetica, (Capitata incertae sedis).
