Discorbis is a genus of benthic Foraminifera (Kingdom Protista in paleontological classifications), that made its first appearance during the Eocene.
Discorbis produces a smooth plano-convex to unequally biconvex trochospiral test (shell) with a flattened umbilical side, taking up about two and a half whorls, with seven to ten chambers in the final whorl.
The test wall is calcareous, thin, optically radial, and finely to coarsely perforate.
The umbilical region is covered by triangular flaps that extend from the umbilical margin of each chamber, forming a small chamberlet beneath.
As an alternative it may be included in the family Pegidiidae, which is elevated from the rotaliid subfamily Pegidiinae.
