Abstract

The available biological information on the association, unique to Australia, between gall-inducing thrips and the phyllodes of Acacia species is summarised. Identification keys to the three genera and 21 gall-inducing species involved are presented, together with descriptions of nine new species (Kladothrips harpophyllae, Kladothrips maslini, Kladothrips xiphius, Oncothrips morrisi, Oncothrips schwarzi, Oncothrips sterni, Oncothrips torus, Onychothrips pilbara and Onychothrips zygus).
