Endoplocus sp. 1

Plate 13: figs 3, 4

Material.

3 specimens, SNSB-BSPG 2016 XXI 1909 –1911.

Description.

Shell broadly trochospiral with strongly convex sides; illustrated specimen 41 mm high; suture somewhat impressed; last whorl large, inflated; transition from whorl face to strongly convex base evenly rounded; whorls smooth; aperture high and narrow; at least one columellar, parietal and palatal (?) plate present.

Remarks.

The shell of Endoplocus inflatus Gründel et al. 2022 is more slender and not as rounded in lateral view. The spire is much more slender and higher. Itieria obtusiceps Zittel sensu Stefano (1884) has a more broadly oval outline in lateral view.
