Kirkbyites Johnson, a valid ostracod genus from the Upper Palaeozoic

Abstract

Abstract. Kirkbyites upsoni Johnson, 1936 from the Upper Pennsylvanian of North America, type species of the poorly understood genus Kirkbyites, corresponds significantly with the well-known species Kullmannissites? solus Becker, 1981 from the Upper Devonian of SW Europe. From common, important diagnostic characters, the latter is considered to be a species of Kirkbyites Johnson, 1936 which is a valid genus of the Family Amphissitidae Knight, 1928 (Ostracoda, Palaeocopida, Kirkbyacea).
