Material examined. Korea, off southhern coast of Jeju, St. 10, 32°30 ʹ 00 ʺ N, 127°00 ʹ 00 ʺ E, 8 Aug 2019, by Smith-McIntyre grab, collected by Nayeon Park and Somin Lee. NIBR GoogleMaps ID: NIBRPR0000110837, MFORBK ID: MFOR BK00222 .

Diagnosis. Test is biconvex, high trochospiral consisting of about three whorls. Spiral side is evolute and conical with broadly rounded apex. Umbilical side is involute, consisting seven to eight chambers, and less convex than the spiral side. Periphery is rounded, circular and thickened by keel. Sutures of both sides are conspicuously limbate and imperforate. Sutures on the umbilical side tend to be stronger near the center. Wall is calcareous, hyaline, and densely perforated except the sutures. Aperture is interiomarginal, extraumbilical with a slight lip. Test diameter is about 1.1 mm.

Remarks. The original name of this species, Eponides bradyi Le Calvez was a junior homonym of Eponides bradyi Earland , and later accepted to Neoeponides bradyi (Le Calvez) by Rögl and Hansen (1984). Based on the original descriptions and previous reports, this species is most similar to N. procerus , among other congeneric species in having high trochospiral, conical test with round- ed apex ( Ellis and Messina, 1940; Hottinger et al., 1993; Szarek, 2001; Hayward et al., 2010). However, N. procerus has a flat, truncated umbilical face and higher conical spiral side with a larger number of whorls than those in N. bradyi . Additionally, the sutures of N. procerus are indistinct unlike those of N. bradyi . The present Korean specimen is most similar to the specimen reported by Szarek (2001) from the Sunda Shelf.

Distribution. Korea, Sunda Shelf, New Caledonia, Maldives, Papua New Guinea.
