| Abstract: | Edgecombe, G.D. March 2007. Acaste (Trilobita: Phacopina) from the Early Devonian of Tasmania. Alcheringa 31, 59-66. ISSN 0311-5518. The widespread Siluro-Devonian acastid trilobites Acaste and Acastella are known from few occurrences in Australasia, these being confined to Lochkovian strata in Victoria and New Zealand. A new species, Acaste andersoni, is described from a correlative of the Bell Shale near St Valentines Peak in north-western Tasmania. Acaste supplements the biogeographic links between the Early Devonian faunas of New Zealand, Victoria and Tasmania. Gregory D.
