Holotype ZMB CNI 14816 .

Material examined: ZMB CNI 14816.

Diagnosis: polyp—solitary with 4 cusps per whorl.

Description: Based on original description, and Morandini & Jarms (2005). Only known from the polyp stage. Polyp solitary; 8.4 mm in total length; light brown color; 0.58 mm basal disc; 0.14 mm diameter just above the basal disc; 0.34 mm diameter at 2 mm height and 0.64 at 5 mm height; aperture 0.96 mm in diameter; 5 whorls of 4 internal cusps.

Type locality: Antarctic Ocean (65°S 85°E), 2,450m depth.

Distribution: Only known from type locality.

Remarks: This species was diagnosed based on one polyp SEM, which revealed 4 internal cusps per whorl, the same as N. simplex . Nevertheless, N. simplex has only one whorl of internal cusps and was described from Greenland.
