Taxonomic remark From original description: this smooth triserial form does not fit within any described Jurassic or Triassic species or genus known to the author. It does not fit within the four Jurassic genera proposed by Simons et al. (1997), nor does it fit within reticulate-walled Conoglobigerina or pustulose-walled Globuligerina (Gradstein et al., 2017a) on the grounds of its smooth microperforate wall and ornament confined to the area of the bulla. This form does not correspond to any of the genera proposed by Fuchs (1967, 1973), which have as a minimum four chambers per whorl. It also does not correspond with Conoglobigerina pupa of Wernli and Görög (2007), which has much more tightly embracing, compressed chambers (not hemispherical chambers) and a higher coil with shallow sutures.
