 Material examined. 1 specimen. Lombok Is. NSMT E-8214 (1 specimen), Gili Air I., February 5, 1994.   
 Description. Centrodorsal discoidal, 4.2 mm across, 1 mm thick, with cirrus sockets in 1 partly 2 rows; aboral pole flat. Cirri XXII, 18–19, 13 mm long. Longest cirrals (5 th –7 th) nearly 2 times longer than wide; cirrals beyond 5 th –6 th with a distal transverse edge; 5–8 distal cirrals with a middle transverse ridge. Radials wholly concealed by centrodorsal. IBr 2; Ibr 1 oblong in contact laterally: Ibr 2 (axil) low pentagonal. IIBr all 2. Rays in a plane. Ossicles of division series and basal brachials smooth without distal spines. Arms 20, 80 mm long. First syzygy at br 1+2; middle brachials beyond br 5 slightly shorter than wide, with oblique articulation and slightly everted distal margin. P 1 longest, 16 mm long, of 45 segments; combs of 13–15 teeth confluent with inner edge of pinnulars. Pinnule combs to P 4. First 2 pinnulars of P 2 –P 4 each with a large fin-like expansion.   
 Remarks. Among the 10 Comatella specimens from Gili Air of Lombok Island, 9 larger specimens (20–50 arms) were identified as C. nigra, and only this smallest specimen (20 arms) was as C. stelligera. The larger specimens have twisted division series and stout arms, while this specimen has plane division series and slender arms.   
 Distribution. Maldives, Sri Lanka, Bay of Bengal, Indonesia, northern Australia, Philippines, China (A. M. Clark and Rowe 1971); Myanmar (A. M. Clark 1972); southern Vietnam (Mekhova and Britayev 2012); Papua New Guinea, Micronesia (Meyer and Macurda 1980; Messing 1994); Timor Sea (Rowe and Gates 1995); South Pacific Ocean (A. M. Clark and Rowe 1971); South China Sea (Lane et al. 2000); Taiwan (Chen et al. 1988); Japan (A. M. Clark and Rowe 1971; Kogo 1998, 2006; Pilcher and Messing 2001; Kogo and Fujita 2005). Depth range: 0–210 m (Lane et al. 2000).
