Three distinctive new genera of Australian Catantopine grasshoppers (Orthoptera : Acrididae)

Abstract

Three distinctive new genera of Australian catantopine Acrididae, Scurra, Pyrgophistes, and Kakaduacris, with their type species, are described and figured. The first two are apparently monotypic, the third with at least two species. Scurra is fully winged in both sexes; Pyrgophistes has macropterous males and brachypterous to mesopterous females; and Kakaduacris is micropterous. The distribution of the type species is plotted on the basis of the available material and some features of the biology indicated.
