Neotype Designation for Coregonus fluviatilis (Salmonidae: Coregoninae) from the Only Known Museum Specimen

Riverine hump-nosed whitefish was described as a new species Coregonus fluviatilis by Issatschenko in 1925 based on eight specimens from the middle Yenisei River basin. The further fate of these specimens is still unknown. At the same time, C. fluviatilis has been involved in various confusions related to its taxonomic position, type locality, distribution, diagnostic characters, and the identification of two forms under the same name. In this regard, in this paper, the neotype of C. fluviatilis (ZMMU P-24531) is designated in accordance with the conditions set out in Article 75.3 of the International Code of Zoological Nomenclature.
