Rodzaj Praeflexiclymenia Czarnocki, 1989

Gatunek typowy
Clymenia tenuis Sobolew, 1912 from the clymeniid limestone at Łagów-Dule, Holy Cross Mountains.

Opis

Diagnosis. — Narrow tabulate venter of moderately evolute conch.

Remarks. — The type species of the genus is actually located at the extremity of the morphologic diversity of species included in it, probably related to Stenoclymenia. Unfortunately, there seems to be no other generic name available to encompass these early clymenias. Hexaclymenia Schindewolf, 1923, with widened whorl cross section but still relatively narrow tabulate venter seems to be a derivative of Praeflexiclymenia. Its origin from Pleuroclymenia is a possible alternative.
