Material examined. Korea, Yellow Sea , station 31105 (34°2 ʹ 38.52 ʺ N, 125°29 ʹ 52.5 ʺ E), 11 Apr 2015, by Van Veen Grab, collected by Sangjin Kim. NIBR ID: NIBR PR0000107220 .

Diagnosis. Test free, small and ovate in outline. Distinctly raised trimarginate keel complex at periphery, central keel more extended, starting at the ends of aperture, and lateral keels staring from middle part of apertural edge. Wall calcareous hyaline, and perforate especially on inflated sides. Aperture terminal, fissure, with a lip.

Remarks. Cerebrina claricerviculata was originally classified within the genus Lagenosolenia McCulloch, 1977 . There are eight extant species reported in the genus Cerebrina , internationally. This is the first record of this genus in Korea. Our specimen is more similar to the specimen reported from Japan by Akimoto et al. (2002) than the specimen reported from New Caledonia by Debenay (2013) in having slightly more broadly rounded basal end.

Distribution. Korea, Japan, New Caledonia.
