New species and occurrences of Bradleya Benson, 1972, Harleya Jellinek & Swanson, 2003 and Poseidonamicus Benson, 1972 (Ostracoda: Cytheroidea) from the Atlantic Sector of the Southern Ocean
The Southern Ocean shelf ostracod fauna is quite well known, while the bathyal and abyssal ones remain poorly understood. Herein, Recent Thaerocytheridae ostracods collected from deep regions in the Atlantic Sector of the Southern Ocean are described and figured. The discovery of Bradleya mesembrina...
