Taxonomy

Citation: Globigerinita Brönnimann, 1951
taxonomic rank: genus
Type species: Globigerinita naparimaensis Brönnimann, 1951 [now regarded as a junior synonym of G. glutinata]
Synonyms:
Taxonomic discussion: Brönnimann’s (1951) original concept of Globigerinita and Family Globigerinitidae was based on the presence of an umbilical bulla with multiple infralaminal openings (see also Bolli and others, 1957:37). This included his species Globigerinita naparimaensis along with other macroperforate forms such as Catapsydrax that are now regarded as unrelated. The genus Globigerinita was used in this sense (essentially a form-genus) by several workers including Brönnimann and Resig (1971) and Blow (1979). However Parker (1962:252-253) drew attention to the distinctive wall texture of Globigerinita, which she described as “smooth, or finely hispid, and nonspinose”. Parker took the bold step of uniting in the genus Brönnimann’s (1951) Globigerinita naparimaensis with Bolli’s (1957) Globigerina juvenilis, and two modern species that had been described in the nineteenth century, Globigerina glutinata Egger, 1893 and Pylodexia uvula Ehrenberg, 1861. She also described a new species from Holocene sediments, Globigerinita iota (now placed in the closely related genus Tenuitella). She clearly stated her opinion that Globigerinita constitutes a separate group from the other planktonic foraminifera and was of uncertain family affiliation (‘Incertae Familiae’) possibly “developed independently from some other ancestry” (Parker, 1962:244). Fleisher (1974:1021-1022) used high quality SEM images to illustrate and describe the microperforate wall and followed Parker in suggesting that the genus should be restricted to forms with this distinctive wall texture. [Pearson et al. 2018]

Loeblich and Tappan (1957) distinguished what they regarded as forms with a ‘true’ bulla from forms with a final chamber (that may have multiple openings) positioned over the umbilicus. They revised their concept of Globigerinita to include forms with an encroaching final chamber and erected a new genus and species, Tinophodella ambitacrena, for what they regarded as ‘truly’ bullate forms, using one of Brönnimann’s paratypes of Globigerinita naparimaensis to typify their genus and species. We do not follow the distinction between ‘true’ bullae and encroaching final chambers, hence we regard Tinophodella as a synonym of Globigerinita (see also Parker, 1962:246). [Pearson et al. 2018]

DATA ON Globigerinita naparimaensis IS NOT SHOWN

Dear Francisco Parra

Thank you for pointing that out - it is really useful to have these comments. The explanation is that G. naparimaensis is regarded as junior synonym of G. glutinata so does not appear in the list of sister species. I will make that a clearer on the page. In general though if you are looking for information on a particular species it is always worth doing a search on its name, that should take you to the different pages where it is discussed.

best wishes
