Odostomia tenuisculpta is a species of sea snail, a marine gastropod mollusc in the family Pyramidellidae, the pyrams and their allies.

[3][4] The yellowish shell has an elongate-ovate shape with the early whorls spirally lirate and the later ones only obsoletely so.

The whorls of the protoconch are small, smooth, obliquely, almost completely, immersed in the first of the succeeding turns.

The columella is strongly curved, reinforced partly by the attenuated base, moderately reflected anteriorly.

It bears a strong fold at its insertion, which appears as if it were the inflected termination of the columella.
