Catalog entries: Zeauvigerina parri
Type images:Distinguishing features:
Parent taxon (Zeauvigerina):
This taxon: Differs from other Eocene zeauvigerinids by lacking a produced neck and lip surrounding the terminal aperture. It further differs from Z. zelandica by its more elongate test that is parallel-sided for most of its length.
