Abstract
The dinoflagellate cyst genus Discorsia Duxbury and its type species Discorsia nanna (Davey) Duxbury are emended. The morphological reinterpretation of the genus is proposed on the basis of new material from core samples of an exploratory bore hole drilled at Puduvoyal, Tamil Nadu, southern India, as well as on re‐examination of the holotype. The Discorsia cysts are interpreted as gonyaulacacean possessing a four plate apical archeopyle (tA). The redefined paratabulation of the genus as indicated by intratabular processes is 4', 6?, (as), Oc, 5–6?', ps, 1p, 1??.
