Remarks.
No specimens of this taxon were examined by us. The holotype is deposited in the Nishinomiya Museum (NC-H204; Kazunori Hasegawa, pers. comm. 2015). The drawing in the original description shows a shell with two parallel R3 swellings, which justifies the distinction of that form at least at subspecies level.
