Abstract

The type specimens of Polystomella minutaReuss, 1865, have not been found in the Reuss collection of the Museum of Vienna. No topotypic specimen is known and all the subsequent designations of this species in the Oligocene and Miocene are misidentifications. Polystomella falunica Allix, 1913, was discovered again in 1968, and cited in 1980, 1989, 1997, 2009 by one of the authors of this study (JPM) and also a few others (see furthers). It is present in the upper Oligocene of the Paratethys and frequent in the Miocene of France and Paratethys, rare in the Pliocene of France. A neotype is here selected and described.
