Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. K. Lentin et al. 1994 | Acavate to narrowly circumcavate, dorsoventrally compressed peridinialean cysts with the single or outer wall layer being laevigate to granulate. Processes typically tend to show a strong marginate concentration, but occasionally have a more uniform distribution. Processes generally hollow, tubiform to tapering, sometimes with striae and annular thickenings (or septa) along their length; they are distally open or closed and furcate. The archeopyle usually involves the middorsal intercalary alone, which is large hexa isodeltaform, posteriorly extending almost to the equator of the cyst. |
