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.
