<p class="abstract-testo">In the course of an investigation on the major mass extintion event near the P/T boundary, in the vicinity of Shahreza (South Isfahan) in Iran, a stratigraphically significant new species of foraminifera (<em>Dagmarita shahreaensis</em> n. sp.) has been discovered in the Wuchiapingian/Dzhulfian (Late Permian) of central Iran (Hambast Formation). This new species is described and emplaced in the phylogeny of the globivalvulinid foraminifera, which evolved rapidly during the Middle/Late Permian.</p><p class="abstract-testo"> </p>
