STUDY MATERIAL. — JC066: stn 4-2, Coral seamount, 41° 20.708´S, 42° 55.292´E to 41° 20.99´S, 42° 55.12´E, 1300 m, 12/11/2011: 1 (NHMUK 2025.55) .

Distribution. E Indo-W Pacific (480–1019 m), S America (79–1738 m), Kerguelen (247– 247 m), S Australia (640–2340 m), New Zealand (27–1365 m), Antarctica (74–835 m), St Paul/Amsterdam Is (420–1680 m), Coral seamount (1300 m).

Remarks. This specimen is small (2.5 mm dd) and we were unable to obtain a DNA sequence. The radial shields are contiguous distally, it has the classic robust stumps of this species, 4 arm spines, the upper longest, and 3–4 oral papillae. Ophiosemnotes conferta is a brooder and it is likely to contain cryptic species (O’Hara & Thuy 2022).
