Finiclymenia wocklumensis (Lange, 1929) from the P. jugosus Zone at Kowala and Jabłonna in the Holy Cross Mountains. 

Diagnoza

Porównanie

The conch from Jabłonna is only partially exposed on a hard limestone block, but sections across ventrolateral spines (or tubercles) are visible in juvenile part up to about 10 mm diameter. At later stages the conch is virtually smooth, although in the probably conspecific specimen from Kowala described by Czarnocki numerous transverse riblets are developed near the venter. Suture is unexpectedly underived, which may suggest that the conch morphology is also primitive for the lineage, despite its stratigraphic location. The only other species of similar morphology is the more evolute K. kozhimensis Bogoslovsky et Kuzina, 1980 from the polar Urals.
