Three new species of jumping plant-lice (Psylloidea) are described from Western Australia. Acizzia hughesae sp.n. occurs on Acacia veronica Maslin (Fabaceae: Mimosoideae), A. mccarthyi sp.n. on an undescribed species of Grevillea (Proteaceae) identified by the Western Australian State Government as in need of conservation action (Grevillea sp. ‘Stirling Range’) and Trioza barrettae sp.n. from the critically endangered Banksia brownii (Proteaceae). These new species of jumping plant-lice are considered rare, and at risk of extinction, or coextinction, as they are recorded from plant species with highly restricted distributions in the south-west of Western Australia. Indeed, the Western Australian State Government recently classified two of the three new jumping plant-lice species as threatened.
