Distribution Amphisbetia distans was considered as a circumtropical species by Ramil & Vervoort (1992, as Sertularia distans), and circumglobal by Calder (1991, as Tridentata distans). In the southeastern Atlantic, it is known from Angola (Broch 1914, as S. distans), Vema Seamount (Millard 1966, as S. distans gracilis) and South Africa (Millard 1975, as S. distans). Its bathymetric distribution ranges from 0 (Millard 1975; Cornelius 1995, as Tridentata distans) to 826 m (Ramil & Vervoort 1992).
