Material examined. Korea: off southhern coast of Jeju, St. 6, 33°00 ʹ 00 ʺ N, 126°30 ʹ 00 ʺ E, 5 Aug 2019, by Smith-McIntyre grab, collected by Nayeon Park and Somin Lee. NIBR ID: NIBRPR0000110836, MFORBK ID: MFORB K00281 .

Diagnosis. Test is large, elongated, uniserial, rectilinear, and slightly tapering toward basal end. Chamber height is increasing as added. Sutures are straight and right-angled to the vertical axis. Surface is ornamented by strong, raised longitudinal costae extending from basal spine to around the aperture of final chamber. Basal spine is slightly oblique to vertical axis. Wall is calcareous and hyaline with smooth and glossy surface. Aperture is terminal, radiate, and slightly produced outward. Test length is about 3.5 mm including the basal spine.

Remarks. This species was originally identified as Nodosaria raphanus by Brady (1884), then Boomgaart (1949) proposed this species as a new species with a new name, Nodosaria bradyi in his doctoral dissertation based on the inconsistency between the type figures of N. raphanus and Brady’s specimens. Later, Thalmann (1950) reported a new name, Nodosaria lamnulifera because N. bradyi was a homonym of Dentalina bradyi Spandel, 1901 = Nodosaria (Dentalina) bradyi (Spandel) . Nodosaria lamnulifera differs from N. raphanus based on the fewer longitudinal costae, non-lobulate periphery and less tapering test. The present specimen is most similar to the specimen of figure 7 in plate 64 reported by Brady (1884), and has a slightly more produced aperture than other specimens (figs. 6, 8-10) in Brady’s plate.

Distribution. Korea, New Zealand, Fiji, Aegean Sea.
