Material examined.

- Kei Islands: 1 specimen, MNHN-IU-2019-4917, Stn. CP 35, 06°08'S, 132°45'E, 390-502 m depth, 27 October 1991.

Diagnosis.

Capitulum compressed, elongated; 14 plates, sculptured with radiating ribs; inframedian latus triangular; rostro-lateral plates very low; penis and caudal appendages absent.

Description.

Capitulum with all plates strongly ribbed, lines of growth marked by fine, inconspicuous striation. Tergum with occludent margin straight, carinal margin convex, but straight concave near apex. Scutum with occludent margin convex, other margins straight, apex slightly overlapping tergum. Carina evenly curved with flat roof bordered by strong ridges; upper latus quadrangular; rostrum small, triangular, overlapped at sides by rostral latera; inframedian latus very narrow. Peduncle shorter than capitulum, covered with strong scales. Cirrus I with unequal rami (anterior ramus: 11 segmented, posterior ramus: 13 segmented). Maxilla globular with serrulate setae; maxillule not notched; mandible with three major teeth, lower margin with three to four denticles. Measurements of two specimens: height of capitulum 12.07-18.59 mm, width 6.17-11.47 mm, thickness 2.68-5.41 mm; length of peduncle 6.30-8.33 mm, width 3.21-5.41 mm.
