Abstract
Taxonomic revision of the Idalima aethrias (Turner, 1908) (Agaristinae) complex from northern Australia indicates that it comprises three distinct species according to morphological criteria: I. aethrias from northern Queensland (southern Torres Strait, Cape York Peninsula, Wet Tropics), Idalima cyanobasis Hampson, 1910 reinst. stat. from north-western ‘Top End’ of the Northern Territory and Kimberley (Mitchell Plateau) of northern Western Australia, and Idalima petrina sp. nov. from the Northern Territory (Arnhem Land Plateau) where it is parapatric with I. cyanobasis reinst. stat. Idalima luna Buchsbaum & Chen, 2020 syn. nov. is shown to be a junior subjective synonym of I. cyanobasis Hampson, 1910 reinst. stat.
Key words: Dilleniaceae, Gulf of Carpentaria, Kakadu National Park.
