Citation: Globigerinelloides Cushman&ten Dam 1948
taxonomic rank: Genus
Type species: Globigerinelloides algeriana Cushman and ten Dam, 1948
Taxonomic discussion: For extensive discusson see Verga & Premoli Silva 2003 (two papers) and Moullade et al. (2002). The disivion of Early Cretaceous species into large multi-chambered and small few-chambered forms, as used in the table above, follows Verga & Premoli Silva (2003a,b).

Original description: Test planispiral, in the early stages similar to Globigerinella, in the adult becoming somewhat loosely coiled, the earlier coils all visible in side view; chambers globular in the earlier stages, in the adult with lateral prolongations reaching to and slightly over the preceding coil; wall calcareous, perforate; aperture at the base of the last-formed chamber in the median line.- Upper Cretaceous.

Entries in the Catalog of original descriptions: Globigerinelloides, Blowiella

Distinguishing features:
Parent taxon (Globigerinelloididae): Test planispiral, chambers globular to radially elongate; aperture at the base of the chamber face and equatorial in position, lateral portions of primary aperture may remain open as new chambers are added, forming relict openings around the umbilical region.
This taxon: 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): at top of Middle Albian Substage (100% up, 107.6Ma, in Albian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Valanginian Stage (132.60-137.70Ma, base in Valanginian stage). Data source: Total of ranges of species in this database

Genus is feminine 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!
