A third <i>Kirkbyites</i> species, <i>K. hercynicus</i> sp. nov., is described from the early Upper Devonian (early Famennian) of the Harz Mountains (Central Europe) to join the other two known species of the genus <i>Kirkbyites upsoni</i> Johnson, the Upper Carboniferous type species from Nebraska (U.S.A.), and the late Upper Devonian <i>Kullmannissites</i>? <i>solus</i> Becker from N Spain (W Europe). Its biotype indicative carapace features, characteristic of marine low-energy palaeo-environments, place <i>Kirkbyites</i> Johnson, 1936 (Ostracoda, Palaeocopida, Kirkbyacea, Amphissitidae) into Becker’s “Thuringian” ecotype.
