Abstract

Stenosemus albus (Linnaeus, 1767), previously considered widespread in the Northern Hemisphere, is absent from the northern Pacific. Instead, the new species Stenosemus magnidentis sp. nov., occurs there. This new species differs from S. albus in the shape of the central tooth and the head of the major lateral tooth of the radula.
