Psolidium acorbulum Thandar, 2006: 38 , fig. 13.

Material examined. Non-type material: IE-2007-808 (1 broken specimen; sampled in front of Nazendry Bay)

Remarks. This species was previously known only from the type material that was collected on the South East coast of South Africa between 710 – 775m. The depth of collection of the studied specimen is unknown (marked as ‘croché’ or meaning attached in the cruise report and as 0 m on the label). However the coordinates of station DW3239 correspond exactly to those of stationCP3293: 268 – 408 m. This record thus extends the bathymetric distribution of P. acorbulum .
