Abstract
The species of Encarsia Förster known from Australia are revised. This study is based mainly on material collected over the last 10 years. Ninety‐four species are recognized, including 38 new species, and seven new records for Australia. All species are fully described or diagnosed, and illustrated by microphotographs. Seven new specific synonymies are proposed and two lectotypes are designated. A key to the females of Australian species of Encarsia is provided. The known hosts and distribution are summarized. The diversity of the Australian Encarsia fauna is discussed.

We are also grateful to Paul De Barro and Jon Martin (the Natural History Museum, London, UK) for the identification of whitefly adults. Identifications of whitefly and scale insect host plants by Alice Wells (Australian Biological Resources Study, Canberra, Australia) and staff of the Australian National Botanic Gardens in Canberra is also gratefully acknowledged. The Australian Biological Resources Study is gratefully acknowledged for financial support of part of this study, which was otherwise largely funded by CSIRO, and we acknowledge in particular the support of Paul De Barro. Sincere thanks to Emilio Guerrieri, John Noyes, and Paolo Pedata for their reviews of, and comments on, the manuscript of this paper, which led to great improvements, particularly in the key.
