A confusing nomenclatural history has resulted in the persistence of the idea that Parazygiella montana (C. L. Koch, 1834), a Palearctic species of orbweaver (Araneae: Araneidae), occurs in the Great Lakes states. I discuss this nomenclatural history and report upon all available material from the Great Lakes states to show that P. montana has never been recorded from the region, and that all previous records of Zygiella/Zilla montana refer to a native species, Zygiella nearctica Gertsch, 1964. Although Z. nearctica has been collected from mainland Michigan and Wisconsin historically, all post 1960 records of this species are from islands in Lakes Michigan and Superior. This suggests that changes on the mainland (perhaps due to introduced species) may have resulted in the decline of Z. nearctica in this region.
