Article 74.7.3 of the Code continues to destabilise zoological nomenclature: repeated lectotypification of Lemmus obensis bungei (Rodentia: Cricetidae)

Abstract. In 2023, B. Kryštufek and G.I. Shenbrot published a paper in which they proposed to consider invalid 20 lectotype designations based on the specimens in the collection of mammals at the Zoological Institute of the Russian Academy of Sciences (St Petersburg). They also designated a lectotype for Lemmus obensis bungei Vinogradov, 1926. We argue that the authors’ decision was based on an incorrect interpretation of Article 74.7.3 and some other Articles and Recommendations of the International Code of Zoological Nomenclature. The history of Article 74.7.3 is briefly reviewed to highlight its destabilising nature and to draw attention to this within the zootaxonomic community.
Key words: nomenclature, stability, lectotype, designation, Mammalia, Rodentia, Cricetidae, Lemmus obensis bungei
