Shell to 14.0 mm in length, elongate-ovate and stumpier than other species of the genus, teleoconch of 5-6 almost flat-sided whorls, protoconch incomplete but consisting of 3+ smooth, glassy embryonic whorls. Post-embryonic whorls sculptured with deep axial and spiral grooves which produce 3 spiral rows of nodules, penultimate whorl with 5 rows and body whorl with 11-14 rows of nodules and additional 8-9 smoother cords basally; on the last two whorls nodules are regular, elevated and round, close-set and sometimes touching each other and connected to each other both laterally and vertically; interspaces are deep and the nodules are regularly aligned in both directions. Aperture slightly longer than the spire, narrow, smooth within, outer lip convex and constricted basally, columella with 4 strong folds, siphonal canal straight. White in color, ornamented with reddish-brown streaks which are saturated in blotches, occasional nodules colored reddish-brown, aperture creamy-white and with 2 faint orange-brown zones.

This is a wider species (W/L = 0.42 to 0.43 in illustrated specimens) than the prior two species. The spire is about equal to the aperture (S/L = 0.49 to 0.51 in illustrated specimens) as in the prior species. The spire sides are nearly straight and the dorsal notch is minimal. The sculpture differs from other species in this genus by the axial riblets and spiral cords being more convex and higher, making the nodes at intersections more nearly beads. In our illustrations the primary spiral cords and nodes are not divided by a spiral groove. The outer lip is convex from the suture to a moderately sharp transition into the anterior canal. There are about 3 or 4 significant folds on the columella on most specimens. The Suduiraut specimen that extends the range from Hawaii to the Philippines has a groove that tends to divide major cords into two parts. The holotype and paratype illustrated in Cernohorsky (1991) differ in the spiral cords on the paratype being more separated than in the holotype. The color of the shell exterior is white to cream with brown to brown-red prominent on some nodes often in axial streaks.

This distinct Hawaiian species differs from all other Neocancilla species in the deeply incised sutures and regular rows of round, close-set nodules. The generic position requires confirmation.

Range - Hawaiian Islands. In mud, sand and coralline algae, to a depth of 200 m.
