Material examined. 2 specimens. Ambon Is. NSMT E-8188 (1 specimen), Lilibooi, 15–20 m, December 9, 1992 . Lombok Is. NSMT E-8247 (1), Gili Trawangan I ., February 13, 1994.

Description. Centrodorsal thin discoidal, roundish or stellate in aboral view, 2.5– 3 mm across, up to 0.5 mm thick, with cirrus sockets in 1 aligned row. Cirri I–XII, 11–12, 6 mm long. Longest cirrals (4 th –7 th) 2 times longer than wide; all cirrals smooth without aboral spine. Radials trapezoidal, in contact laterally. IBr 2: Ibr 1 oblong, in contact laterally; Ibr 2 (axil) low pentagonal, free laterally. IIBr and IIIBr all 4(3+4).

PII longest, 11–15 mm long, of 40 segments; combs of 10–12 discrete teeth non-confluent, with pointed tip; 3–4 pinnulars often with small secondary tooth. P 1 similar to PII, excessively longer than succeeding pinnules. Pinnule combs to P 2.
