Diagnosis Test trochospiral, planoconvex to inequally biconvex with flattened umbilical side, about two and a half whorls, seven to ten chambers in the final whorl, sutures curved and nearly radial, depressed, periphery rounded to subangular, a triangular alar projection or flap extends from the umbilical margin of each chamber over the umbilical region, forming a small chamberlet beneath, successive flaps may fuse in the central region, internally an imperforate proximal wall (paries proximus) within the chamber adheres to the septum peripherally, expanding as a lobe toward the chamber base where it may or may not attach to the chamber floor, separating the foramen into two parts, the more peripheral in position communicating with the preceding chamber, and the umbilicalmost one opening into the chamber extension beneath the alar projection; wall calcareous, thin, optically radial, finely to coarsely perforate, surface smooth; aperture a low, interiomarginal, extraumbilical arch, a secondary opening at the posterior margin of the umbilical flap leading into the chamberlet and remaining open as new chambers are formed. Eocene to Holocene cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
Grammatical gender ICZN Art. 30.1.1. a genus-group name that is or ends in a Latin word takes the gender given for that word in standard Latin dictionaries; if it is a compound word formed from two or more components, the gender is given by the final component (in the case of a noun, the gender of that noun; in the case of any other component, such as a Latin suffix, the gender appropriate to that component).
Disc-orbis ("disc-circle") is masculine because "orbis" is a masculine noun in Latin. [details]
