Description. O’Loughlin and Ahearn (2008) provide a recent and comprehensive description of this species. The material examined here concurs with this description.

Distribution. Antarctica, South Sandwich Island, South Shetland Island, Bouvet Island, 146–759 m; New Zealand, Hikurangi Margin, Kermadec Trench, Southern Plateau, 66– 1669 m (this paper).

Remarks. Psolidium whittakeri O’Loughlin and Ahearn, 2008 is so far only known from the Southern Ocean around Antarctica. This current material has extended the range of this species around the Antarctic continent, as well as northwards into Subantarctic and temperate latitudes. Additionally, the reported depth range has been extended from 759 m to 1669 m at the more northern record ( NIWA 49868).
