Holotype MCZ 6237, Atlantis station 2953, Bahia de Corrientes, Cuba, 1125m.

Main Features: Disc tumid with many small scales. Radial shields small, widely separated. Glabrous surface. Long arm joints, surface of arm plates contour-ridged, distal arm segments elongated. Diamond-shaped dorsal arm plates throughout. Two then 3 arm spines, uppermost pair transformed into hooklets, lowermost longest—equalling one arm segment. Small oral shields and many interradial plates. Short genital slits originating away from oral shield and just one arm segment long. Oral papillae not separated. Two pairs of exposed tentacle pores, each with 1 scale. 9–10 ventral arm plates.

This species resembles O. stellatum, the only differences seem to be the length of the genital slits and the length of the lowermost arm spines distally.
