Material examined SOUTH ATLANTIC OCEAN • 2 colonies, up to 19 mm high, without gonothecae; Vema Seamount, stn Dive 4; 91–95 m depth; 1 Feb. 2015; SEAFO-2015 leg.; SEAFO-2015-40020, SEAFO-2015-40131. Distribution Obelia dichotoma is a well-known species with a nearly cosmopolitan distribution (Cornelius 1995); it is absent from Arctic and Antarctic waters (Peña Cantero & García Carrascosa 2002). In the Southeast Atlantic, it was reported from Angola (Vervoort 1959, as Laomedea ( Obelia ) dichotoma ) and South Africa (Millard 1975). Its bathymetric distribution ranges from the intertidal (Cornelius 1995) to 540 m (Vervoort 2006).
