Abstract. The holothurian paraspecies Achistrum brevis Mostler, 1971 from the Norian of Hernstein (Lower Austria), is a junior homonym of Achistrum brevis Gutschick, 1959. A. brevis Gutschick, 1959 is a significant element in the Lower Mississippian of northern Indiana, USA (Gutschick, 1959, 132). In consideration of this homonymy, it is proposed that Achistrum brevis Mostler, 1971, is changed and designated as Achistrum hagdorni Mostler & Reich nom. nov.
