ABSTRACT
Cavernacmella dentata Fukuda, Sawada & Kameda, n. sp. is described from the inside of the Sekigahara Limestone Cave, Gifu Prefecture, central Honshū, Japan. The new species is unique in the genus and the Assimineidae in having a strong fold on the parietal lip of the aperture, but according to its internal anatomy and a molecular phylogenetic analysis it is a member of Cavernacmella Habe, 1942.
