Laevipilina antarctica Warén & Hain 1992: 167, figs 2 –5, 6–8, 10–16, 19, 27.
This species, originally described from the Weddell and Lazarev seas, Antarctica, had a bathymetric range from 210–644 m (Warén & Hain 1992). Recent additional reports by Schrödl et al. (2006) include a first abyssal record for this species. The abyssal specimen comes from soft bottom terraces 3 km to the SW edge of the Wegener Canyon (70 ° 38.46 ’S, 14 ° 42.87 ’W – 70 ° 39.19 ’S, 14 ° 43.44 ’W), Weddell Sea, where it was collected at 3102–3136 m depth.
This was not only a considerably range extension but also the first indication that this genus is found at abyssal depths.
