Rediscovery of the holotype of Petaurus notatus Peters 1859 (Petauridae; Marsupialia) and clarification of the type locality

A recent integrative taxonomic study concluded that the sugar glider, Petaurus breviceps (sensu lato), comprises more than one species and that Petaurus notatus Peters 1859 should be resurrected as the available name for one of the two newly circumscribed species. The type specimen of Petaurus notatus has been considered to be lost, leading to a neotype being nominated. A recent search of the type collections of the Museum für Naturkunde, Berlin, located the holotype and we provide photographs and a morphological description of the skin and partial skull. The neotype should now be set aside. The type locality of Petaurus notatus is also clarified, correcting misinterpretations of locality information provided in the original type description and recent texts.
