Kalloclymenia pessoides (von Buch, 1839) from the P. jugosus Zone at Kowala in the Holy Cross Mountains and Dzikowiec in the Sudetes.

Diagnoza

Compressed subquadrate whorls with smooth flanks; ribbing disappears at about 30 mm diameter.

Porównanie

The species is unique among those of Kalloclymenia in its virtually smooth adult conch. The parabolic nodes at juvenile stages disclose the close affinity to K. subarmata.
