MD50 CP7, north-east of Île Amsterdam, 37° 47.2´S, 77° 38.98´E, 1680– 940m, Beam trawl, 9/7/1986, MNHN IE.2019.4746 (holotype), MNHN IE.2009.1569 (9 paratypes). Holotype description . Disc is 8.3 mm dd, arms are coiled distally but are at least 25 mm long. Both sides of the disc and the arms are covered in skin that obscures underlying plates. Disc is five lobed, constricted interradially, covered in skin with embedded low conical granules (Fig. 7D). The granules are largest on and between the radial shields and in the centre of the disc (0.27–0.3 mm dia), on the dorsal and ventral interradii they are smaller (0.18– 0.25 mm), sparser and separated by skin and small scales. The wide genital slits are contiguous with the first 2 arm segments (Fig. 7E). Oral shields are rhomboid, 1.5 times wider than long; adorals are almost of the same size, trapezoid, widest proximally, 2 times as wide as long, meeting broadly interradially, slightly tumid; teeth robust, pentagonal, pointed at tip, 3 conical papillae on the ventral margin of the oral plate, the adoral shield spine is slightly larger. DAPs are fan-shaped, as wide as long, with a rounded distal margin and acute angle proximally, separate. Some disc granules are present along the base of the arm and between DAPs of the first few segments. VAPs are wider than long, pentagonal with an obtuse proximal angle, rounded distal margin and straight lateral margins, separate. Arm spines are rounded in cross section and tapering to a blunt rounded tip, rugose but not thorny. First segments have 3 short spines, 4 on next 2 segments; beyond the disc there are 5–6 arm spines, uppermost to as long as a segment, lower spines 2/3 to half as long (Fig. 7F). Near the arm tip, the 3 spines become slender, subequal, less than a segment long and have thorns on the ventral side (Fig. 7G). Tentacle pores are small with a tiny pointed tentacle scale on ...
