Material examined

SOUTH ATLANTIC OCEAN • 2 colonies, up to 10 mm high (1 growing on ghost fishing net) and with gonothecae; Valdivia Seamount, stn BT12, 24°49′01″– 24°47′38″ S, 6°24′40″– 6°25′26″ E; 887– 886 m depth; 7 Feb. 2015; SEAFO-2015 leg.; SEAFO-2015-40811, SEAFO-2015-40887.

Remarks

Campanulina denticulata   was considered a synonym of Earleria panicula (G.O. Sars, 1874)   by several authors ( Leloup 1974; Schuchert 2003), but Calder (2012) suggested that the Atlantic E. panicula   is a different species from the Indo-Pacific C. denticulata   . The comparison of the material from the Valdivia Seamount with colonies of E. panicula   collected in NW Africa showed some morphological differences, and agrees with descriptions of C. denticulata   given by Clarke (1907) and Vervoort (1966).

Distribution

Campanulina denticulata   has an Indo-Pacific distribution ( Calder 2012). Its bathymetric distribution extends from more than 500 m (Clarke 1970, as Opercularella denticulata   ) to 4040 m deep ( Vervoort 1966, as O. denticulata   ).
