Material examined.

- Tanimbar Island: 1 specimen, MNHN-IU-2019-4919, Stn. CP 87, 08°47'S, 130°49'E, 1017-1024 m depth, 5 November 1991.

Diagnosis.

Capitulum with 13 plates covered by very thin, chitinous membrane; carina simply bowed, flat roof with umbo apical; upper latus quadrangular or rather pentagonal, lower edge being truncated; inframedian latus elongate, quadrangular; carinal latus large, elongate, umbo near base; peduncle short.

Description.

Capitulum flatted, elongate, plates separated by narrow, chitinous interspaces. Scutum quadrangular, umbo apical, occludent margin arched. Tergum triangular with umbo slightly produced apex. Carina with bowed, flat roof, increasing little in width from upper to lower. Upper latus irregularly trapeziform; rostral latus with umbo at top of rostral margin; infra-median latus irregular, quadrangular, elongate, narrow; carina latus quadrangular. Cirrus I unequal, anterior ramus broader than posterior ramus; cirrus VI with short caudal appendages. Maxillule slightly notched, two large spines on upper side; mandible with three large teeth excluding inferior angle; labrum slightly convex, with numerous teeth.
