Description

Voucher material, NHM_329, disc approx 20mm in diameter. Additional voucher material (12 specimens) ranges in size from 2mm to 20mm in diameter (Fig. 20). Range of polymorphs observed characterised by pattern of disc dorsal coloration (Fig. 20). Juveniles observed and identified from DNA data.

Genetic data for this taxa with new GenBank accession numbers are provided in Table 2

Diagnosis

Forms a unique monophyletic clade distinct from other AB01 specimens. Morphologically fits Ophiomusium cf. glabrum detailed in ( Lütken and Mortensen 1899) but no genetic data available from type locality (47°22'N; 125°48'W, 1604m depth) ( National Museum of Natural History, Smithsonian Institution 2015). CO1 sequences of our material is 17% different (K2P distance) from sequences published on Genbank (HM400322-HM400323).

Ecology

The most abundant brittle-star in the UK-1 exploration claim survey box UK-1 Stratum A, frequently observed by the ROV on the sediment surface and on nodules.
