Fahraeusodus adentatus, the type species of Fahraeusodus, is revised based on the re-examination of the original types and a large collection of topotype specimens from the Emanuel Formation (Lower Ordovician) of the Canning Basin in Western Australia. Confirmation of a modified pastinate Pa element in the septimembrate ramiform-pectiniform apparatus of this conodont species has resulted in a redefined generic definition for Fahraeusodus. Based on this newly defined diagnosis of Fahraeusodus and its type species, all other species previously assigned to Fahraeusodus and Texania are reviewed and now placed in Pohlerodus gen. nov., which is erected herein to substitute Texania, which is a junior homonym.Yong Yi Zhen yong-yi.zhen@regional.nsw.gov.au, Geological Survey of New South Wales, W.B.
