Original description: [Shaw Chenglong, 1999b]:
Description:
cyst subspherical to elliptical; marginate cyst; surface feature with penitabular processes which arises from low dissected and incomplete thin septa, from more or less arcuate to rectilinear distally branched process groups; tips of some adjacent process groups may be connected by trabeculae.

apical archeopyle, operculum sometimes indistinct; 37x54 μm.
No indications of paratabulation, paracingulum, or parasulcus.
