A new genus and species of Cerambycidae from the subfamily Lamiinae is described from subtropical rainforest in southeastern Queensland, Australia. Excastra albopilosa gen. et sp. nov. is easily distinguished from all other Australian Lamiinae by its dense covering of short adpressed white setae and the long erect white setae forming twisted spires. A modification to the key to Australian Lamiinae genera is provided to accommodate Excastra gen. nov.
