Paratypes: MNRJP2602: 10 specimens (adult); 24°21′27ı19″S; 44°13′20ı95″W; 245 mı 27 July 2010; on Lophelia pertusa. MNRJP2603: 4 specimens (3 juveniles and 1 larva); 24°21′27ı19″S; 44°13′20ı95″W; 245 mı 27 July 2010; on Lophelia pertusa. Non‑type material: MNRJP2604: 59 specimens; 24°21′27ı19″S; 44°13′20ı95″W; 245 mı 27 July 2010; on Lophelia pertusa. Diagnosis: K‑maxillae comprising a heavily‑sclerotized main fang and seven partially fused plates; P‑maxillae consisting of seven rounded platesı two of them fused and five only partially fused. Uniramous parapodia with a bundle of capillary chaetae occurring only on the supra‑acicular region. Sub‑acicular region possessing a bundle of heterogomph falcigers with slightly serrated blades and single capillary chaeta. Rosette glands from segment eleven on. DESCRIPTION Measurements: Holotype: 3.5 mm longı 0.8 mm wide; Paratypes: mean size: 1.8 mm longı 0.5 mm wide (largest specimen 4.20 mm longı 0.9 mm wide; smallest specimen 0.65 mm longı 0ı 22 mm wide). Body short (holotype with 24 segments)ı stoutı dorsally convexı ventral region flattenedı with longitudinal groove. Both ends are terminally rounded (Figs. 1 A‑B). Bundles of cilia present throughout body. On the prostomium these form a frontal bundle with tufts between the antennae and the eyes (Figs. 1 A‑C)ı while complete rings of cilia occur on each peristomial segment and on the pygidiumı whereas remaining segments possess a dorsal and a ventral bundle of cilia separated by the parapodia (Figs. 1 A‑Bı for dorsal bundle). Fixed specimens with an opaque pale white color (Fig. 1B). Prostomium wider than longer (Figs. 1 A‑C). Anterior border with up to 10 tactile cilia. Cirriform antennae inserted dorsolaterallyı with a tuft of stereocilia on the apex (Fig. 1C). Palps digitiformı stoutı inserted laterally on the prostomium (Fig. 1C). A pair of eyes is ...
