Platytyphlops ledoyeri (Reyss, 1978a) n. comb.

Paralamprops ledoyeri Reyss, 1978a: 12–15, figs 6–7.

Type material. Syntypes: MNHN. Bermuda Transect, North Atlantic, 36°23’N, 67°58’W. Not seen.

Diagnosis. Carapace with 1 pair lateral ridges, marginal carina entire, ridge absent on pseudorostrum; eyelobe without lenses or tumidities. Antennule article 1 not expanded; accessory flagellum 0.8 main flagellum. Telson shorter than uropod peduncles, with 3 terminal setae, central seta longest. Uropod endopod article 1 1.1 length of articles 2 and 3 together. Adult male antennule accessory flagellum and main flagellum equal in length. Antennal flagellum extending to posterior border of pleonite 6.

Depth. 4680–4749 m.

Remarks. Platytyphlops ledoyeri is unique within the genus in having a single ridge dorsal and parallel to the marginal carina, and a short pair of dorso-medial ridges posteriorly. The rest of the species in the genus can be divided into those having only the marginal carina, and those having many ridges dorsal of the marginal carina.
