Bolli & Saunders (1985): The morphological features of G. humerosa are largely those of G. acostaensis, except for its larger test size and higher number of chambers forming the last whorl (6-7 instead of ,1-5), resulting in a less rapid increase of the individual chambers. The division between G. acostaensis and G. humerosa, using number of chambers and test size, is most conveniently placed between 4-5 chambered forms of a maximum diameter up to about 0.4 mm, and 6-7 chambered forms of a size range from about 0.4 to 0.5 min. |
