Hedbergella yezoana is a valid species name: Comments on the case 3620 and decision (opinion 2362) by the International Commission of Zoological Nomenclature

International Commission of Zoological Nomenclature decided in September 2015 on case 3620 submitted by A. Ando (United States National Museum, Smithsonian Institution, Washington, D.C.), which regards the status of the species Ticinella primula Luterbacher in Renz et al., 1963, and Hedbergella trocoidea yezoana Takayanagi & Iwamoto, 1962. Decision was to place the former on the Official List of Specific Names in Zoology and the latter on the Official Index of Rejected and Invalid Specific Names in Zoology (ICZN, 2015, p. 227). The scientific fundamentals in the presentation of case 3620 are weak and do not support such a decision by the International Commission. Moreover, they create a significant disturbance of nomenclatural stability in the Linnaean classification of the Cretaceous planktonic foraminifera.
