Abstract

We describe one new aporrhaid species, Kangilioptera inouei sp. nov., from the Paleocene Katsuhira Formation in Urahoro Town, eastern Hokkaido, Japan. This is the first record of a Cenozoic Aporrhaidae (Anchurinae) gastropod in Japan. Occurrences of Kangilioptera are confined to Paleocene deposits in western Greenland and Japan. With the addition of the bivalve Conchocele, the new find requires a reappraisal of the marine connection through the Bering Strait between Japan and Greenland during the Paleocene.
