Description
Summary:7 páginas, 2 figuras, 1 tabla. [EN] 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) [ES] Se redescribe la antomedusa unitentaculada Paragotoea bathybia a partir de nuevos ejemplares recolectados en el mar de Weddell. El estudio comparativo de las descripciones previas de esta especie nos ha permitido establecer una nueva diagnosis del género que es emplazado dentro de la familia Corymorphidae. Se suprime la familia Paragotoeidae Ralph, donde P. bathybia estaba situada anteriormente. El estadio de 4 tentaculos reconstruido por Ralph (1959) y considerado como el estadio adulto de P. bathybia, es una especie nueva para la que se erige un género nuevo: Tetraralphia hypothetica, (Capitata incertae sedis).
