(Figs 1; 2) TYPE MATERIAL. — North Atlantic Ocean. Armorican margin, 47°30’N, 7°00’W, 1000 m, II.2006, holotype, specimen attached to the deep-sea scleractinian Madrepora oculata (Linnaeus, 1758) (MNHN-Ci3023). ETYMOLOGY. — The species is named after Dr Erwan Le Guilloux who kindly provided the specimen. DIAGNOSIS. — Capitulum with 15 plates, including two subrostra (Figs 1; 2). Rostrolatus overlapping carinolatus. Plates thick, sculptured with longitudinal ridges and growth lines. Carina strongly arched. Scutum triangular with apico-basal ridge dividing plate almost unequally. Tergum rhomboidal with flat apico-basal ridge marked by deep, squared groove. Rostrum higher than wide, strongly convex. Rostrolatus strongly curved inwards and inclined towards rostral side. DESCRIPTION The description is based on the single available specimen, which is not disarticulated. No juveniles were found in the sub-rostral region. Capitulum: height 10 mm, thick plates partly covered by cuticle (Fig. 2). Cuticle partially hiding the ornamentation of plates, mainly in lower whorl, locally breaking, exposing mineralised plates sculptured with marked longitudinal ridges and growth lines. Rostrolatus overlapping carinolatus (Fig. 2 A-D). Carina: broad, length about three times width, bending inwards, strongly arched with tectum transversally convex. Apico-basal ridge raised; four strong longitudinal ridges with obtusely angular growth lines each side of median ridge; basal margin obtusely angular. Scutum: triangular, length almost twice width, apical part slightly inclined towards tergum; moderately convex transversely, with distinct transverse growth lines. Apico-basal ridge nearer to occludent side, dividing plate unequally; three strong longitudinal ridges between apico-basal ridge and raised occludent border, six on tergal side of plate. Occludent margin weakly convex, tergal margin weakly concave. Tergum (Fig. 2E): rhomboidal, elongate, weakly curved away from scutum, length about 2.5 times ...
