Material examined: BBB 2016: St. 18; St. 28; St. 40.

Distribution: Malvinas region (53˚00’S, 60˚00’W, 375 m; 51°55’S, 61°50’W, 200 m); off Staten Island (53°56’S, 63°40’W, 400 m, 54°34’S, 64°W, 84 m); off Patagonia (46°54’S, 60°28’W, 480 m); off Crozet Island (46°53’S,

51°52’E, 1005 m); Burdwood bank (53°56’S, 63°40’W, 400 m) ( Taylor et al. 2013); Elephant Island (61°15´S, 56°24´W, 450 m)( Auscavitch&Waller 2017); Potter Cove, King George Island,Antarctic Peninsula (62°14′27′′S, 58°42′88′′W, 30–45 m) ( Song et al. 2012); Burdwood bank (128–607 m) (present study).

Remarks: Synonyms at the area: Primnoa antarctica Valenciennes, 1846 . Not Thouarella antarctica Hickson 1907 (= unknown), Thouarella (Parathouarella) antarctica Kükenthal 1915 . Not Thouarella (Euthouarella) antarctica Broch 1965 (= T. pendulina ); Not Thouarella antarctica Cairns & Bayer 2009 (= T. chilensis ). Taylor et al. (2013) pointed that an unseen sample was described from Crozet Island at 1005 m by Wright & Studer (1889), so the bathymetric and geographic ranges may be extended.
