Original description: Globigerinelloides Cushman & Ten Dam 1948:

Entries in the Catalog of original descriptions: Globigerinelloides;

Distinguishing features: Test planispirally enrolled, biumbilicate, involute to evolute, lobulate in outline, chambers globular to somewhat elongate in partially evolute species, sutures depressed; wall calcareous, perforate, optically radial; aperture equatorial and interiomarginal, bordered by a narrow imperforate lip, broad and low to moderately arched, the lateral portions remaining open as relict supplementary apertures around the umbilicus when new chambers are added.

Geological Range:
Last occurrence (top): within Maastrichtian Stage (66.04-72.05Ma, top in Maastrichtian stage). Data source: Total of range of species in this database
First occurrence (base): within Valanginian Stage (133.88-139.39Ma, base in Valanginian stage). Data source: Total of range of species in this database

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous

Genus is feminine

30.1.4.4. A compound genus-group name ending in the suffix -ites, -oides, -ides, -odes, or -istes is to be treated as masculine unless its author, when establishing the name, stated that it had another gender or treated it as such by combining it with an adjectival species-group name in another gender form.

Globigerinelloides algeriana Cushman and ten Dam, 1948 the type species indicates the feminine.

Another pain in the neck.

Yes its a nasty problem and one which is still controversial (I think because the ICZN ned to be more ambiguous). I am in negotiation on this!
