Euparthenia
Euparthenia is a subgenus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks in the subfamily Turbonillinae.
The name Euparthenia is a replacement name for Parthenia Lowe, 1841 not Robineau-Desvoidy, 1830.
The genus Euparthenia contains both Recent and fossil species.
