Acute or very narrowly tabulate venter of adult specimens; generalized tornoceratid suture.

Porównanie

 Relatively large specimen MD 11090 from Kadzielnia in the collection of the former Dzieduszyckis’ Museum in Lvov, about 70 mm in diameter, and mature specimen ZPAL AmVII/991 in my collection, of diameter 57 mm, have an almost acute venter with a very narrow tabulation. The complete lineage seems to be represented at Kadzielnia, but the material comes from loose blocks and the exact stratigraphic position of particular specimens is hard to determine.
