Material examined. Korea, East Sea , station E4 (37°55 ʹ 4.816 ʺ N, 128°51 ʹ 11.786 ʺ E), 20 May 2016, by Van Veen Grab, collected by Raehyuk Jeong and Jisu Yeom. NIBR ID: NIBRPR0000107237 .

Diagnosis. Test free, elongated, uniserial, and somewhat curved. Chambers regularly increasing in size as added. Horizontal sutures. Wall agglutinated with medium to coarse sediment particles. Aperture terminal and round- ed at the end of short and cylindrical neck.

Remarks. This species is the type species of genus Nodulina Rhumbler, 1895 , and the only species included in this genus. According to Loeblich & Tappan (1987), the test of this species is similar to that of Reophax species, but Nodulina has more regular, gradually enlarging chambers, horizontal sutures and a straighter axis than Reophax .

Distribution. Korea, China, Japan, New Caledonia, Canada, United States, Bay of Biscay ( France), Celtic Sea, Norway.
