Estaingia bilobata gen. et sp. nov. is described from the upper Lower Cambrian Emu Bay Shale of Kangaroo Island, South Australia. The genus resembles the Siberian genera Lermontovia Suvorova 1956, and Bergeroniellus Lermontova 1940, in the morphology of the cephalon and thorax, but it differs markedly in the structure of the pygidium, which is spinose and bilobed; it has tentatively been placed in the Paradoxididae. The fauna of the Emu Bay Shale also includes new species of Redlichia and Isoxys, and hyolithids. The palaeoecological implications of the association of Estaingia with Redlichia are briefly discussed.
