Splendrillia nenia

The length of the shell attains 6.6 mm, its diameter 2.5 mm.

(Original description) The small, narrow, glossy shell is angled at the shoulder. It contains 5 whorls plus a smooth, tilted, globose, two-whorled protoconch. Its colour is pure white. Its sculpture shows curved, stout shouldered ribs, twelve on the body whorl. These mount the spire obliquely, become obsolete anteriorly, and terminate abruptly at each anal fasciole. The whole shell is covered by fine, close, microscopic growth striae. The base of the shell is contracted. The siphonal canal is short. The aperture is narrow. The anal notch is deep, with a raised, subtubular margin. The columella is slightly arched, overlaid by a thick callus sheet.^[2]
