Wallowiella (Plicaropsis) cancellata (Stahl, 1824) Plate 6: figs 13, 14 (adult), Plate 7: figs 1, 2 (juvenile) 2015 Wallowiella (Plicaropsis) cancellata (Stahl, 1824) – Gründel, Keupp and Lang: 88, pl. 4, figs 5–14; pl. 5, figs 1–4 (here more synonymy and chresonymy). 2016 Wallowiella (Plicaropsis) cancellata Stahl, 1824) – Gründel, Hostettler and Menkveld-Gfeller: 510, pl. 5, figs 5–11. 2017 Wallowiella (Plicaropsis) cancellata (Stahl, 1824) – Gründel: 30, pl. 9 B. Material. Total of 27 specimens; 17 specimens from Saal; 10 specimens from Saal level 4, location 1 (“ Sohle 4, Fundstelle 1 ”); 2 specimens figured: SNSB – BSPG 2016 XXI 1773 –1774. Remarks. Many of the studied specimens from the Sylla collection differ from those reported by Gründel et al. (2015) by having an alternation of weak and strong spiral cords. These weaker spiral cords are, however, distinctly stronger than the lirae of Hayamiella schaeferi Gründel et al., 2015 in the same position. The nodes at the intersections of axial ribs and spiral cords are sometimes elongated like spines. The attribution of the present material to the species Wallowiella (Plicaropsis) cancellata is supported by the square pits formed by axial ribs and spiral cords on the shell and the formation of a knob on the outer lip.
