Original description: [Bujak in Bujak et al., 1908, p. 42]:

Diagnosis:
Autocyst spherical to ovoidal, without apical, antapical, or other projections, except for an ornament of low crests which give the cyst a cerebral appearance. The crests are mostly random, but occasionally suggest a paratabular arrangement.
The archaeopyle is formed by the loss of between one and three precingular paraplates. Archaeopyle formula is P to 3P (3" to 2"-4").

Dimensions:
Autocyst diameter = 24 x 24 µm to 28 x 28 µm. Height of crests to 2 µm.
