Material examined: ZMH C 10693 (four specimens from Portugal, no information on depth), ZMH C 10602 (eight specimens from Morocco 1967, no information on depth), more than 27 specimens kept in culture (polyps from Morocco 1980, depth: 800 – 3,000 m; Mediterranean Sea 2008, depth: 200 m; and Rio de Janeiro, Brazil 2002, depth: 200 – 227 m). Diagnosis: medusa — hyperdome bell, translucid, with straw hat shape; polyp — solitary with 8 cusps per whorl. Description: Based on original description and own observations. Adult medusae 5.7 – 12 mm in diameter with 3.85 – 7.74 mm of this the central disc, with a high translucid hyperdome bell with straw hat shape; marginal lobes partially overlapping, rounded; tentacles up to 7 mm long; rhopalia with statocyst and ocelli; rounded, brown / yellowish, gonads located above the coronal groove (dioecious). Polyp solitary; 2.56 – 31.43 mm in total length; aperture diameter 0.33 – 1.65 mm; 0.08 – 0.40 mm diameter just above the basal disc; 8 cusps per whorl and a maximum of 14 whorls, cusps have additional teeth on the surface; 40 – 50 tentacles; over 100 ephyrae per strobilation. Type locality: Morocco coast, 415 – 420 m depth. Distribution: NE Atlantic Ocean, SW Atlantic Ocean, Mediterranean and Arctic Ocean. Remarks: Examined specimens with a thimble-shaped transparent central disc, with 4 to 8 gastric filaments, which made their identification as N. werneri possible. Gonads are round and yellowish, located under or outside the coronal grove. Maximum diameter of specimens was 7 mm and tentacles were up to 3 mm long. All specimens from Brazil were males.
