Marstonia lustrica is a species of very small freshwater snail which has an operculum, an aquatic prosobranch gastropod mollusc in the family Hydrobiidae.

(Original description as Amnicola oneida) The shell is typically more slender than Marstonia lustrica.

The apex is slightly obtuse, but the first whorl projects noticeably, similar to Marstonia lustrica.

The peristome is continuous, thin, and contacts the preceding whorl very briefly above.

[2] This species occurs at the Oneida Lake, New York, USA.
