The two specimens measure 5.5 mm dd (DC64) and 8.0 mm dd (CP7), the first is relatively intact (Fig. 4F–H) and the second is damaged and distorted with only part of the dorsal disc remaining. They are referred to Ophiophrura on the basis that the disc scales cover the radial shields, the lack of disc spines or granules, the flattened hollow arm spines, the presence of three elongated distal papillae on the jaw which correspond to two adoral shield spines and the distalmost lateral oral papilla, three to four tentacle scales, two of which are placed on the LAP and one to two on the VAP, arm spine articulations that are orientated obliquely to ... : Published as part of O'Hara, Timothy D. & Thuy, Ben, 2022, Biogeography and taxonomy of Ophiuroidea (Echinodermata) from the Îles Saint- Paul and Amsterdam in the southern Indian Ocean, pp. 1-49 in Zootaxa 5124 (1) on page 16, DOI: 10.11646/zootaxa.5124.1.1, http://zenodo.org/record/6404674 ...
