Synonymy: 1936, Contr. Cushman Lab. 12: 85, pl. 15, fig. 4.
Description: Distinguished by the flattened disc-like, planispiral form, with about 16 strongly recurved narrow chambers in the final whorl; internal canal system with openings between the inter- sutural ribs.
Distribution: Kapitean to Recent.
Comment: Easily confused with Discorotalia tenuissima. This species is one of many referable to Elphidium sensu lato in the Cenozoic and Recent. It is included here because it is particularly characteristic of the Pliocene and Pleistocene.
