Abstract
The dictyopharid planthopper genus Anasta Emeljanov from the Australasian region is revised to include six species including a new one: A. australiaca (Lallemand, 1935) comb. nov. (North Australia), A. lobosa sp. nov. (Papua New Guinea), A. minuta (Lallemand, 1935) comb. nov. (Timor, Indonesia), A. prognatha (Distant, 1906) (North Australia, Papua New Guinea), A. timorina (Lallemand, 1935) (Timor, Indonesia), and A. vitiensis Emeljanov et Wilson, 2009 (Fiji). Descriptions or redescriptions of A. australiaca, A. lobosa sp. nov., and A. prognatha are provided together with dorsal habitus and structural illustrations of male genitalia. A key to the species of the genus and distribution map are provided. The biogeography of the genus is discussed.
