Description of genus Loeblich, A., J., R., Tappan, H., 1988, vol.1-2, Van Nostrand, Reinhold, New York

General description

Discoidal test, early chambers are peneroplid, later chambers become annular and divided into chamberlets that are connected by a stolon system. Apertures occur along the peripheral margin, they are more or less circular and surrounded by a calcified rim. Living specimens have a brownish colour due to Symbiodinium endosymbionts.
