Material examined. Ie Island (RUMF-ZE-02042[1], RUMF-ZE-02043[1]): “entrance” of the “Unnamed cave”, approximately 20 m depth, under coral rubble, 8 September 2016 (RUMF-ZE-02042), 24 June 2017 (RUMF-ZE- 02043).

Distribution. Widely distributed in Indo-West Pacific. Depth range 2–1046 m.

Remarks. This species is identified as Ophiothrix purpurea by virtue of having: long aboral most arm spine exceeding five or more times longer than corresponding arms segment on proximal portion of the arm; bearing radial shields without any spines nor stamps; a median dark line running along each ram aborally; more or less numerous spines on aboral disc (e.g. A. M. Clark & Rowe, 1971).
