5. Psolus lockhartae O’Loughlin & Whitfield, 2010 .

We have identified a single specimen from deep water off the Falkland Islands as Psolus lockhartae O’Loughlin & Whitfield, 2010 (WS 840, S of Falkland Islands, 368–463 m, 6 Feb 1932, NHMUK 2016.83). The distribution of Psolus lockhartae was given by O’Loughlin & Whitfield (2010) as Birdwood Bank, South Georgia, South Shetlands and South Orkneys (211–2897 m). The 12 mm long specimen is smaller than the types (up to 20 mm long). The ossicle complement is the same, and the form of the ossicles is similar but the ossicles in the types are larger. We thus have some reservation over our determination.
