Aoteadrillia wanganuiensis is a species of sea snail, a marine gastropod mollusk in the family Horaiclavidae.

[3](described as Pleurotoma wanganuiensis) (Description by Henry Suter) The small, fairly solid, whitish shell has a fusiform shape.

The base of the body whorl is adorned with fine spiral threads, close together upon the beak.

The shell contains 7 whorls, regularly increasing, roundly angled at the middle by the nodules, concave above and below it.

The outer lip is sharp, somewhat strengthened on the outside, moderately convex, contracted below, with a fairly deep and rounded sinus in the depression above the row of nodules.
