Abstract

The alpha taxonomy of the endemic whitefish of lakes Brienz and Thun, Switzerland, is revised. We evaluate the status of seven known species:Coregonus steinmannisp. nov.,Coregonus profundussp. nov.andCoregonus acrinasussp. nov.are endemic to Lake Thun;Coregonus Brienziisp. nov.is endemic to Lake Brienz; andC. alpinus,C. albellus, andC. fatioifrom lakes Brienz and Thun are redescribed. One of these species,C. alpinus, is revised, since the lectotype for this species is incongruent with the species description given by Kottelat (1997) and Kottelat and Freyhof (2007). The nameC. alpinusis thus retained for the lectotype designated by Kottelat (1997) and a new description of this taxon provided. For the species otherwise described by Kottelat (1997) and Kottelat and Freyhof (2007) asC. alpinusthe new nameC. profundusis designated.Coregonus acrinasusis genetically partially of allochthonous origin, closely related to the radiation of Lake Constance, and we therefore compare it to all recognized species of Lake Constance,C. wartmanni,C. macrophthalmus,C. arenicolus, andC. gutturosus.
