Material examined.

- Tanimbar Island: 5 specimens, MNHN-IU-2019-4896, stn. CC 56, 08°16'S, 131°59'E, 549-552 m depth, 31 October 1991; 1 specimen, MNHN-IU-2019-4898, stn. CP 71, 08°38'S, 131°44'E, 477-480 m depth, 2 November 1991; 6 specimens, MNHN-IU-2019-4901, stn. CP 72, 08°36'S, 131°33'E, 676-699 m depth, 2 November 1991.

Diagnosis.

Capitulum compressed, oval, notched above; surface covered with very short velvety pubescence, areas of valves defined by grooves, lines of growth strongly marked; carina flattened.

Description.

Capitulum with 14 plates, cartilaginous thick. Terqum irregularly triangular, apex projecting above carina, recurved. Scutum triangular, basal width more than half height, apex overlapping tergum. Carina evenly curved, apex projecting freely for short distance, touching or entering between terga, its base rounded, widely separated from carinal latera; roof strongly convex. Upper latus triangular with base convex. Rostrum triangular; inframedian latus small, triangular, base deeply embedded. Peduncle with large transverse plates, not overlapping (widely spaced). Cirrus I unequal, anterior ramus oval, posterior ramus slender, long; cirrus VI with caudal appendages. Maxillule with oral edge sinuous, a large seta at its proximal third, another at its distal end; mandible with four teeth. Measurements of five specimens: height of capitulum 16.94-39.25 mm, width 11.39-28.28 mm, thickness 5.20-19.89 mm; length of peduncle 15.02-52.02 mm, width 5.63-16.87 mm.
