Stenoclymenia sandbergeri (Wedekind, 1908) from the P. trachytera Zone at Ostrówka and Jabłonna  in the Holy Cross Mountains.

Diagnoza

Porównanie

Specimens with ribs, considered typical for S. sandbergeri, are rare in the Holy Cross Mountains material. The prominence and distribution of ribs is higly variable and this suggests that these are extreme morphotypes of the species. Specimens that do not bear ribs are usually classified in Platyclymenia prorsostriata Schindewolf, 1920. Do not having enough information on the variability in the type populations I am not able to decide which of those names should be applied to the Polish material.
