Material examined Holotype ATLANTIC OCEAN • adult ♀; Southeast Atlantic, collected from off Angola; 2063 m deep site; 12°03′ 3 S, 12°20′ 5 E; Dinet leg.; MNHN AF 05/77 Ma. Additional specimens ATLANTIC OCEAN • 1 adult ♀; North Atlantic; 2205 m deep; Dinet & Vivier leg.; MNHN AP 345/560Ma. MEDITERRANEAN SEA • 1 adult; Cassidaigne Canyon; 460 m deep; Vitiello & Vivier leg.; MNHN AE120 /78Ma. Remarks There were two primary purposes for the re-examination of this taxon. One purpose was to identify the secondary and tertiary clavae, which were not reported in the original description (Renaud-Mornant 1981). The second purpose was to accurately understand the morphology of the leg IV sensory organs, which was described as hemispherical papillae in the text, but drawn as elongate papillae in the figure of the original description (Renaud-Mornant 1981). Unfortunately, the secondary and tertiary clavae were not recognised in the holotype, MNHN AF05/77Ma. However, they were evident in the additional specimen, MNHN AP345/560Ma. In this specimen, the paired secondary clavae were positioned in the dorsal area between the median cirrus and the primary clavae and each was in the form of a flat, distorted-oval lobe (the complete contour was not recognisable) (Figs 2, 3A). The paired tertiary clavae were position ventrally, immediately posterior to the external cirri and each was in the form of a flat, transversally-elongated lobe with a slight indentation where the external cirrus arises (Figs 2, 3B).
