| G.L. Eaton 1976 | Dinoflagellate cysts having a spherical or subspherical body with a smooth or finely fibro-reticulate surface. Process intratabular, fibrous, simple or branched. A variable proportion of the processes are distally united by fibrous membrane. Processes invariably present on the apical, pre- and postcingular and antapical zones. Typically each reflected plate area has one process, sometimes more than one. Cingular zone usually, but not invariably, devoid of processes.
