Material examined

SOUTH ATLANTIC OCEAN • 2 colonies, growing on algae, without gonothecae; Vema Seamount , stn BT5; 31°37′16″–31°36′58″ S, 8°22′37″–8°23′06″ E; 71–94 m depth; 31 Jan. 2015; SEAFO-2015 leg.; SEAFO-2015-40437 , SEAFO-2015-40768 , LZM-UV slide R. 577 .

Distribution

Campanularia africana has previously been reported from Australia ( Watson 1990), Japan ( Stechow 1923; Leloup 1938; Hirohito 1995) and Natal, South Africa (Millard 1975). Its bathymetric distribution extends from the littoral area to a depth of 102 m (Millard 1975; Stechow 1925). Our finding of C. africana at Vema Seamount represents the first record of this species for the Atlantic Ocean.
