Hirasea katoi Habe

Kato’s Hirasea Snail (Hirasea katoi)

Kato’s Hirasea Snail was described in 1973 based on only two specimens that were collected from dune deposits of probable Pleistocene age on the island of Minamijima in the Ogasawara archipealgo, Japan.

The shells reached sizes of 0,3 cm in height, they were very flat, opercular in shape with an extremely depressed spire and a sharply marginated periphery. [1]


The species probably disappeared sometimes at the end of the Pleistocene or the beginning of the Holocene.
