Original Description: This subspecies differs from B. globigerinelloides (Globigerina globigerinelloides Subbotina, 1949) in possessing chambers which, in the final whorl, become as high as long, with more deeply indented intercameral sutures and a more lobulate periphery. On the spiral side, the chambers of early whorls are globular to reniform, but as the later chambers become higher they occupy 38-40% of the total test diameter (as compared to 30% in the typical form of the species).

Extra details from original publication: Remarks: Blefuscuiana globigerinelloides (Subbotina) s. s. has not yet been found in the Aptian of Speeton, although it was recorded by Subbotina (1949) to range from the upper part of the Early Aptian at least to the lower part of the Early Albian in the Caucasus. Gorbachik (1986) believed that “Hedbergella” globigerinelloides had an even younger range (Late Albian to Cenomanian) but she included in this records of H. modesta (Boli, 1959) which she believed to be a junior synonym. We have found B. globigerinelloides lobulata only in the upper L. cabri zone of Speeton (Sample 8103).
