Data for: A taxonomic revision of ten whitefish species from lakes Lucerne, Sarnen, Sempach, and Zug, Switzerland, with descriptions of seven new species (Teleostei, Coregonidae)

The taxonomy of the endemic whitefish of the lakes of the Reuss River system (Lucerne, Sarnen, Zug) and Lake Sempach, Switzerland, is reviewed and revised. Lake Lucerne harbours five species. Coregonus intermundia sp. nov. and C. suspensus sp. nov., are described. Coregonus nobilis Haack, 1882, C. suidteri Fatio, 1885, and C. zugensis Nüsslin, 1882, are redescribed. Genetic studies have shown that C. suidteri and C. zugensis are composed of several distinct species endemic to different lakes. The names C. suidteri and C. zugensis are restricted to the species of lakes Sempach and Zug, respectively. The whitefish populations previously referred to as C. suidteri and C. zugensis from Lake Lucerne are described as C. litoralis sp. nov. and C. muelleri sp. nov., respectively. Furthermore, the whitefish from Lake Zug that were previously referred to as C. suidteri are described as C. supersum sp. nov. A holotype is designated for C. supersum that was previously one of two syntypes of C. zugensis. The other syntype is retained for C. zugensis. Coregonus obliterus sp. nov. is described from Lake Zug, and C. obliterus and C. zugensis from Lake Zug are extinct. Finally, we describe C. sarnensis sp. nov. from lakes Sarnen and Alpnach. Coregonus suidteri from Lake Sempach shows strong signals of introgression from deliberately translocated non-native whitefish species, which questions if the extant population still carries a genetic legacy from the original species and thus may need to be considered extinct. Coregonus suspensus is genetically partially of allochthonous origin, closely related to the radiation of Lake Constance. It is therefore compared to all known and described species of Lake Constance: C. wartmanni Bloch, 1784, C. macrophthalmus Nüsslin, 1882, C. arenicolus Kottelat,1997, and C. gutturosus Gmelin, 1818.

本研究对瑞士罗伊斯河系湖泊（琉森湖、萨嫩湖、楚格湖）及森帕赫湖的特有白鲑属（Coregonus）鱼类分类学开展了系统综述与修订。琉森湖曾记录有5个物种，本次研究记述了其中两个新种（sp. nov.）：Coregonus intermundia sp. nov.与Coregonus suspensus sp. nov.；同时对Coregonus nobilis Haack, 1882、Coregonus suidteri Fatio, 1885及Coregonus zugensis Nüsslin, 1882进行了重新记述。遗传学研究表明，C. suidteri与C. zugensis实则由多个分别适应不同湖泊的特有物种构成，因此将C. suidteri与C. zugensis的学名分别限定为森帕赫湖与楚格湖的特有物种。原被归为C. suidteri与C. zugensis的琉森湖白鲑种群，分别被记述为Coregonus litoralis sp. nov.与Coregonus muelleri sp. nov.。此外，原被归为C. suidteri的楚格湖白鲑种群被记述为Coregonus supersum sp. nov.。本次研究为C. supersum指定了正模标本，该标本原是C. zugensis的两份合模标本之一，另一份合模标本则保留给C. zugensis。本研究还从楚格湖记述了Coregonus obliterus sp. nov.，而楚格湖原有的C. obliterus与C. zugensis现已灭绝。最后，我们从萨嫩湖与阿尔卑纳赫湖记述了Coregonus sarnensis sp. nov.。森帕赫湖的C. suidteri种群表现出强烈的人为引种外来白鲑物种导致的基因渐渗信号，这引发了学术疑问：现存种群是否仍保留有原物种的遗传印记，因此该种群或可被认定为已灭绝。Coregonus suspensus在遗传学上部分具有异地起源，与康斯坦茨湖的物种辐射演化支系亲缘关系密切，因此本研究将其与康斯坦茨湖所有已知及已正式记述的物种进行了比对：Coregonus wartmanni Bloch, 1784、Coregonus macrophthalmus Nüsslin, 1882、Coregonus arenicolus Kottelat, 1997及Coregonus gutturosus Gmelin, 1818。
