This chapter examines the post-glacial population distribution of mayflies in New Zealand. It explains that the mayfly population was isolated after New Zealand was separated from Antarctica and the eastern coast of Australia during the late Cretaceous period, and that the survivors evolved into the present fauna, which includes 42 species. The result of the analysis supports the view that a center of population dispersal of double gilled leptophlebiid was in northern New Zealand and that glaciations in the south resulted in a different pattern of radiation of some single-gilled species. The chapter argues that the pattern of distribution is not necessarily purely the result of biogeographical processes.Less
