Remarks We recorded three specimens from the South China Sea at 917 m to 1911 m depth. Disc diameter ranges from 17 to 20 mm . The specimens are similar to the holotype description by Wyville Thomson (1873) and to the first description from the South China Sea in Liao (2004) ( Fig. 13A–G ). The arm spine articulations are placed at the distal edge of the lateral arm plate ( Fig. 14A–D ). The vertebrae have a long zygospondylous articulation, a short, moderately large podial basin at the proximal end, and are small and narrow at the distal end. The dorsal end of the vertebrae is distally triangular and proximally flattened, with a long longitudinal groove along the midline, without furrow ( Fig. 14E–H ). The ventral end of the vertebrae has a broad midline longitudinal groove without an oral bridge ( Fig. 14G ). Ophiomusa lymani has been recorded from deep waters in both the East and South China Seas. Distribution 130–4829 m depth. East China Sea, South China Sea, Arabian Sea, Indonesia , Australia , New Zealand , Chile , Gulf of Mexico, Caribbean, Atlantic Ocean and South Africa ( Olbers et al. 2019 ; OBIS 2021 ).
