While new species are most commonly described based on recent field collections, undertaken at poorly explored places, some are identified in museum collections, where they have spent decades before being recognised as new to science. Such is the case of an unusually large and likely extinct ground beetle found at the Muséum national d’Histoire naturelle, Paris, whose story began in the distant 1860s with Dr. Eduard Graeffe’s trip to Samoa. Now, a century and a half later, the beetle is finally described by Dr. James K. Liebherr, Cornell University, USA, in the open access journal Zoosystematics and Evolution.
