Material examined. Holotype NHM UK 2013.1121, Stn 299: Pacific, Southeast (Peru-Chile Trench off Valparaiso); 3950 m.

Supplementary descriptions. Newman & Ross (1971) and Young (1998b), latter showed the plates only.

Distribution. Pacific, Southeast and Southwest; Antarctic; Indian Ocean. Known depth range 1230 to 4810 m.

Remarks. There is uncertainty concerning the taxonomic status of this species. No reliable characters have been found to separate it from similar species, such as T. moluccanum ( Hoek, 1883) , T. regium (W. Thomson, 1873) and T. gigas ( Hoek, 1883) ( Foster & Buckeridge, 1995a; Young, 2007). Most authors (e.g. Newman & Ross, 1971; Young, 1998b), however, have included it in the Arcoscalpellum michelottianum group delimited by Pilsbry (1907a).
