Abstract While there have been many reports of the species ‘Berkeleya scopulorum’ from Northeast Asia mainly as Navicula scopulorum, the observation of the living specimen of the species has revealed that the species should be the member of the genus Climaconeis. Here we describe the species as Climaconeis mabikii sp. nov. based on microscopic observations by means of both light (LM) and scanning electron microscope (SEM). As part of the review, the regional distribution of C. mabikii as well as the worldwide biogeography of the taxa belonging to the genus Climaconeis are discussed. Newly described C. mabikii from the present study is the seventeenth member of the genus. The discovery of the true identity of the diatom identified for a long time as ‘Berkeleya scopulorum’ and its description as a new Climaconeis species contributes to the proper appreciation of the diversity of the Northeast Asian diatom assemblage and fills old gaps in the published records.
