Toumarkine & Luterbacher (1985):
The large number of chambers in the last whorl (6 to 8), which increase very gradually in size, is the main feature of this rather small, hispid and biconvex Acarinina. The general aspect of the test is compact and the periphery nearly circular.
Blow (1979) distinguished two subspecies, a more tightly coiled, Globorotalia (Acarinina) broedermanni broedermanni, and a G. (A.) broedermanni anapetes (Figs. 29.21-22) which is more loosely coiled, has a flatter spiral side and a more widely open umbilicus. |
