• Popis: The rare and endangered freshwater snail Marstoniopsis insubrica (Küster, 1853) (Gastropoda: Amnicolidae) today has a highly disjunct distribution in Europe. We abstracted all known published Holocene fossil records of Marstoniopsis insubrica, previously reported as M. scholtzi. The early Holocene records from Hungary together with the new record from southern Slovakia fill a distribution gab between northern and southern present populations. Because of the presence of continental ice sheet that covered much of northwestern Europe during the last cold stage, it is likely that the modern distribution of M. insubrica in most of northern Europe is of postglacial origin. These fossil records can therefore suggest a possible dispersal pathway of postglacial spreading from southern refugia to the north, in a southeastwards direction along the Alps, thought the location of its glacial refugia are unknown.
