Neogloboquadrina dutertrei blowi

Citation: Neogloboquadrina dutertrei blowi Rögl & Bolli 1973
Rank: sub-species
Type specimens: Plate 9, Figures 19-22; Plate 17, Figure 12
Type repository: Basel, CH; Natural History Museum

Current identification/main database link: Neogloboquadrina dutertrei (d’Orbigny, 1839)

See also: Globigerina subcretacea ;

Original Description

The large test is low trochospiral with five chambers in the last whorl. The arched aperture is of average height and remains umbilical-extraumbilical in position throughout ontogeny. The wall is similar to Neogloboquadrina dutertrei dutertrei, usually with thick incrustations and a fine crystalline surface (Plate 17, Figure 12). The species differs from N. dutertrei dutertrei in that the aperture remains umbilical-extraumbilical, and from Neogloboquadrina dutertrei pseudopima in the increased number of chambers in the last whorl and in the wider umbilicus. [Rögl & Bolli 1973]

Extra details from original publication
Nomen novum introduced for Globigerina subcretacea Chapman, 1902
[from Rögl & Bolli 1973]:  NB The green text in the synonymy has been introduced by me as an attempt to rationalise the synonymy as printed [JRY 2017]. The printed text makes no sense, since it does not cite Lomnicki 1901 and gives the wrong date for Chapman 1902. It appears that a line of text went missing during publication. 

Taxonomic remarks: - Globigerina subcretacea was described by Lomnicki from the Miocene of Wielicka, Poland, and compared by him with Globigerina (cretacea d'Orb.?) of Brady, 1884. This comparison was based on the similarity of coiling between the Miocene form and the Recent one figured by Brady. Examination of material from Wieliczka, kindly made available by Mrs. E. Luczkowska, Krakow, has shown that the Miocene Globigerina subcretacea Lomnicki is a true spinose Globigerina with an umbilical-extraumbilical aperture. It is likely that the species evolved from the Miocene Globigerina concinna Reuss.
Blow (1969) selected a lectotype for Globigerina subcretacea Lomnicki from the Globigerina (cretacea d'Orb.?) Brady material, without having seen specimens from the Miocene type locality. Because the synonymy proposed by Lomnicki with the Recent form of Brady is erroneous, Blow's lectotype is also not valid. Only the Recent Globigerina subcretacea described by Chapman, 1902, where Brady's form is also cited in the synonymy list, compares with the lectotype of Blow.
As a homonym it is, however, invalid. Neogloboquadrina dutertrei blowi nom. nov. is therefore introduced here.  [Rögl & Bolli 1973]

Occurrence: According to Blow from Late Pliocene to Recent. With some interruptions present through Site 147.  [Rögl & Bolli 1973]"

Editors' Notes
This was a new name for Globigerina subcretacea Chapman 1902 which was a homonym of Globigerina subcretacea Lomnicki 1901. The confusion here seems to have been increased further by mistakes in the synonymy given by Rogl & Bolli 1973. [JRY 2017]
