Citation: Gallitellia Loeblich & Tappan, 1986
Rank: genus
Type species: Guembelitria vivans Cushman, 1934

Taxonomic discussion:
All Cretaceous and Paleogene triserial forms posses an asymmetrical aperture with a small toothplate. For this reason we include Jenkinsina in the synonymy of Guembelitria. Gallitellia, however, differs from Guembelitria in more than ornamentation alone. It lacks both the distinct apertural lip found in Guembelitria as well as a toothplate. These differences appear to be more fundamental. We therefore retain the genus Gallitellia. [Kroon & Nederbragt 1990]

Catalog entries: Gallitellia, Neogallitellia

Distinguishing features:
Parent taxon (Benthic origins): Biserial (separate evolutionary origin)
This taxon: Initially biserial may become multiserial, smooth, microperforate wall; aperture simple (no lip or toothplate).

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.

I was more than reluctant to introduce those new replacement names. "Unfortunately" they are available and valid. ICZN is very clear on homonymy but if you know of a way to conserve the foram name...



Gallitellia Loeblich & Tappan, 1986 (preoccupied) was replaced by Neogallitellia Özdikmen, 2009. Please see:

Thanks - a necessary evil.

I've looked into this a bit further and it is not totally straightforward, since the name Gallitellia Cuif 1977 was apparently an objective junior synonym, so at the very least the relevant specialists could legitimately apply to conserve the foram name.
