Material examined. 1 specimen. Lombok Is. NSMT E-8195 (1 specimen), Gili Air I ., February 3, 1994.

Description. Centrodorsal thin discoidal, circular in aboral view, 0.8 mm across, with 10 cirrus sockets in 1 aligned row. Cirri IV retained, 8, 4 mm long, with knobby articulation. Longest cirrals (2 nd –3 rd) 2.5 times longer than wide; middle and distal cirrals slightly longer than wide, without aboral spine; opposing spine prominent. Rays in a plane. Division series widely separated each other. Radials oblong, in contact laterally at base. IBr 2; Ibr 1 rectangle, slightly wider than long, Ibr 2 (axil) pentagonal. Arms 10, 45 mm long; first syzygy at br 3+4. P 1 longest, 5 mm long, of 21 segments, with 8 teeth confluent teeth with outer edge of pinnulars; first comb tooth transverse; combed pinnulars with transverse bar; some pinnulars longer than wide. P 2 and P 3 absent; P 4 4 mm long, of 10 segments, with 0–4 confluent teeth. P 5 4 mm long, of 10 segments, no comb. Pinnules slender; no recognizable gonad; middle and distal pinnulars spiny at distal margin. Pa and Pd present; Pb and Pc absent.

Remarks. This specimen belongs to the genus Comanthus for having a small centrodorsal, exposed radials and a few cirri, though could not be identified to a particular species. Some proximal pinnules are not developed probably because this specimen is a juvenile.
