We describe the wingless viviparae and sexual forms of Aphis carverae sp. nov., a new endemic species of Aphis Linnaeus, 1758 from Australia. The species is holocyclic and monoecious on Epilobium (Onagraceae). No winged individuals have been found. Casimira canberrae (Eastop, 1961) is another endemic aphidine species from Epilobium. We describe the winged viviparous and wingless sexual female morphs of this aphid, which is also shown to be holocyclic and monoecious. Native aphids feeding on Onagraceae in Australia are under serious competitive threat from the recently introduced Aphis oenotherae Oestlund, 1887.
