Proposes a new classification for the Australian Heteroptera based on the most recent developments in heteropterology worldwide. The proposed classification departs significantly from all previous treatment of the Australian fauna. There is a comprehensive treatment of the classification and nomenclature of the Australian species and a thorough review of the literature concerned with the higher classification of the Pentatomomorpha. Includes detailed information on the distribution and ecology of each species and features the first in depth listing of their host associations. All species and generic synonymies are given, including extra-limital synonyms, along with detailed type specimen data.
