Acrotriche orbicularis was first formally described in 2010 by Michael Clyde Hislop in the journal Telopea from specimens collected east of Ravensthorpe in 2008.[2] The specific epithet (orbicularis) means 'orbicular', referring to the shape of the leaves.[3]
This species is found in the understorey of low woodland on Bandalup Hill east of Ravensthorpe in the Esperance Plains bioregion of south-western Western Australia.
This species is listed as "threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is in danger of extinction.[4]
