Original description: [Dodecova, 1990]:

Description:
Proximo-chorate cyst, sphaerical to subsphaerical. Wall two-layered with thick autophragm and thin ectophragm. Ectocoel occupied by fibrous, irregular in shape and dimensions sheaves. Cyst`s apical horn short, built by ectophragm only. Narrow asymmetrical cingulum is dividing the cyst into nearly equal halves. Sulcus narrow, extending from mid-epicyst to the antapical plate. Tabulation marked by distinct sutural crests with indented, varying in length distal edges.
Tabulation formula: 0-3pr, 4`, 0-2a, 6``, 6?c, 6```, 1p, 1````, 6s. Plate 1p is elongated, plate 1```` asymetrical, ventrally inclined. Intratabular crests are irregularly found on the plates of the precingular and postcingular series.
Archaeopyle epicystal, combination, type E. Specimens with operculum ventrally attached, as well as single epi- hypocysts are encountered, too.
