Original Description

Test of small size for the genus, thick and compact, composed of about 2 whorls, about equally biconvex, periphery rounded and blunt, umbilicus large and open; chambers indistinct, about 6 in the last-formed whorl, very gradually increasing in size as added, slightly inflated; sutures depressed, curved on the dorsal side and radial on the ventral side; wall covered by a thick, short, coarse spines; aperture a narrow, low opening under the ventral edge of the last-formed chamber, without a lip.

Length 0.33 mm.; breadth 0.28 mm.; thickness 0.18 mm.

Etymology:
The species is named in honor of Ing. Jorge Brödermann, Director del Mapa Geologico de Cuba

Extra details from original publication
This species resembles G. albeari n. sp., particularly in dorsal view. It differs, however, in its large, open umbilicus and its less acute periphery.
G. broedermanni is found only in the Capdevila formation of the lower Eocene where it is a good index fossil.


Editors' Notes
The specific name was published as brödermanni, this is correctly latinized as broedermanni
