Depth range. 300–2600 m (most commonly at about 2000 m).

Iberian Seas published records. SE Bay of Biscay continental slope (Lagardère 1983, 1985, Petryashov 2014). Cap Breton canyon (unpublished data). Off Calician and Asturias coasts (Lagardère 1983). Azores /Biscay rise close to the margin of the Iberian-Abyssal Plain (42ºN–17ºW: Angel et al. 1982). Offshore species related to the Canary Archipelago (Nouvel 1942, Wittmann & Wirtz 1998, Haroun & Garrido 2003, Wittmann & Riera 2012). Off Madeira (Tattersall & Tattersall 1951). Azores (Nouvel 1943, Tattersall & Tattersall 1951).
Remarks. Due to the presence of this species in Italy (Vives 1968, Wittmann & Ariani,2010) we suspect that it is likely be found in the Iberian Mediterranean Sea.
