Citation: Globigerinoidesella El-Naggar 1971
taxonomic rank: genus
Type species: Globigerina fistulosa Schubert 1910

Catalog entries: Globigerinoidesella

Distinguishing features:
Parent taxon (Globigerinidae): Wall spinose, usually with 3½-6 globular chambers in final whorl, trochospiral or planispiral
This taxon: Supplementary apertures, cancellate wall & elongate extensions to final chamber.

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
They are being edited as the site is developed and comments on them are especially welcome.
