Ellobium mizutanii sp. nov. is described from the lower Miocene Yamanouchi Member of the Akeyo Formation (Mizunami Group) in Shitaoki-cho, Mizunami City, Gifu Prefecture. This is the third fossil species of the genus Ellobium from the Cenozoic of Japan. The present species closely resembles Ellobium chinense (Pfeiffer), a living species that can be found in regions including Mikawa Bay (Aichi Prefecture, central Japan), northern Kyushu, and southern China, but differs in having an inflated body whorl and rather broadly expanded callus on the parietal area of the aperture.
