Abstract

Imagoes, sub-imagoes and nymphs of a new species of Tasmanian mayfly (Tasmanophlebia lotis sp.nov.) are described based on morphological, ecological and genetic differences between it, the only other known Tasmanian species in the genus (T. lacustris) and congeneric species on the Australian mainland. Tasmanophlebia lotis is widely distributed in rivers at low elevations across the island, in contrast to T. lacustris, which is found in high-altitude lentic habitats. The separation of mainland Australian and Tasmanian species of Tasmanophlebia is consistent with similar observations based on genetic analysis of other Australian mayflies, and suggests differentiation well prior to the flooding of Bass Strait during Holocene deglaciation.
