Abstract
Ten genera of Ocydromiinae (Diptera: Hybotidae) are recorded from the Australasian Region, including Leptodromia Sinclair & Cumming, 2000. The endemic Australian genus Leptodromia is revised with seven species recognized, including six new species (L. bickeli Barros & Sinclair sp. nov., L. castanea Barros & Sinclair sp. nov., L. immaculata Barros, Freitas-Silva & Sinclair sp. nov., L. lineata Barros & Sinclair sp. nov., L. nebulosa Barros & Sinclair sp. nov. and L. t-maculatum Barros, Freitas-Silva & Sinclair sp. nov.). The type species, L. bimaculata (Bezzi, 1904) is redescribed. An identification key to species is provided and the species distributions mapped.
