In our earlier paper ( Páll-Gergely et al. 2017) we overlooked that Gredler (1891) already synonymised A. pentagonus with A. anthostoma .

Protoconch low, glossy, without spiral lines; R1 rather regularly ribbed, ribs low, no spiral striation visible; R2 relatively long, with ribs curved towards the aperture, forming a smooth surface.
