ABSTRACT

Solitary scyphistomae of the scyphozoan order Coronatae were sorted from samples collected at 12 oceanographic stations of the Revizee-Score Sul/Bentos project along the Brazilian coast. The 201 specimens were found, at depths between 133-808 m, growing on stony corals. These scyphistomae were assigned to the families Nausithoidae (186) and Atorellidae (15) based on the outer morphology of the periderm tubes. The number and shape of the cusps, and the presence of second order teeth in some of them, suggests that the polyps should be split into four types, two of them assigned to Nausithoe Kölliker, 1853 and two others to Atorella Vanhöffen, 1902. Living stephanoscyphistomae should be collected and reared to further resolve the taxonomy of these scyphozoans.

RESUMO

Cifístomas solitários de cifozoários da ordem Coronatae foram triados a partir de amostras coletadas em 12 estações oceanográficas do projeto Revizee-Score Sul/Bentos na costa brasileira. Foram encontrados 201 espécimes, entre as profundidades de 133-808 m, crescendo sobre corais pétreos. Estes cifístomas foram identificados nas famílias Nausithoidae (186) e Atorellidae (15) com base na morfologia externa dos tubos peridérmicos. O número e forma dos espinhos internos, e presença de dentes de segunda ordem em alguns espinhos, sugere que os pólipos sejam separados em quatro tipos, dois deles identificados como Nausithoe Kölliker, 1853 e outros dois como Atorella Vanhöffen, 1902. Estefanocifístomas vivos deveriam ser coletados e cultivados para melhor esclarecer a taxonomia destes cifozoários.
