Type locality.

"Ichihashi (limestone region), Ikeda-cho, Ibi-gun, Gifu-ken, Japan"

Material examined.

NSMT-Mo 64217 (holotype); 岐阜縣 1揖斐郡池田町 (Gifu-ken, Ibi-gun, Ikeda-cho = Gifu Prefecture, Ibi County, Ikeda Town), coll. Sakurai, NSMT-Mo 79094 (2 shells).

Remarks.

The protoconch of the holotype probably has a growth disorder, and its sculpture could not be fully examined. It was low, very finely granulated, and the last 0.25 of the whorl was wrinkled. The specimens in the Sakurai collection have normally developed protoconchs, which were low and finely granulated, without spiral lines; R2 has ca. 30-32 low, blunt ribs; most ribs are completely merged with the neighbouring ribs nearer the tube; ribs free at edge of body whorl; space between ribs ca. 2 × as wide as an individual rib; no spiral lines visible on R1.
