A new Early Permian (Aktastinian-early Baigendzhinian, early Artinskian) brachiopod fauna is described from the Aiduna Formation, which crops out in the upper reaches of the Mapia River, southern Irian Jaya. New taxa are Neochonetes (Sommeriella) irianens is sp. nov., Chonetinella aidunaensis sp. nov., Sulcataria skwarkoi sp. nov., and Aulosteges tenuispinosus sp. nov. Although material is fragmentary, the new fauna demonstrates significant links with Early Permian faunas of Western Australia and peninsula Thailand. The Carboniferous-Permian brachiopod biostratigraphy of Irian Jaya is reviewed, and known faunas are shown to range in age from probable Namurian to early Kungurian.
