Trigonoclymenia spinosa (Münster, 1842)from the P. trachytera Zone at Ostrówka and Besówka in the Holy Cross Mountains .

Diagnoza

Ventrolateral parabolic nodes expressed on conch internal moulds as more or less apparent tubercles.

Porównanie

Platyclymenia unisulcata Czarnocki,1989, showing prominent ventrolateral tubercles, may belong here. Specimen ZPAL AmVII/027 from sample Ost-7 at Ostrówka shows a Clymenia-like septal morphology, although the suture is not suitable to prepare a camera lucida drawing. In fact, as the shell surface is not preserved, it cannot be excluded that this is a morph of Nodosoclymenia distincta Czarnocki, 1989.
