Taxonomy of the Genus Phaulacridium and a Related New Genus (Orthoptera : Acrididae)

The economically important grasshopper genus Phaulacridium is comprehensively revised. Three Australian and two New Zealand species are recognised and described, of which P. crassum and P. howeanum (both Australian) are new. The species Phaulacridium nanum is removed and allocated to a new genus, Minyacris, along with a new species, M. occidentalis. Distributions of all species are plotted and interpreted.
