Taxonomy
Original description: The test is similar to that of Globigerinella escheri escheri, except that the end chamber, occasionally also the penultimate one, is distinctly prolonged in radial direction, thus producing in lateral view a broad ellipsoid, non-tapering outline.
Entries in the Catalog of original descriptions: Globigerinella escheri clavata
