The ‘smooth newt’ Lissotriton vulgaris, consists of multiple morphologically distinct taxa. In a recent study, driven by genetic data, we recognized five species, L. graecus, L. kosswigi, L. lantzi, L. schmidtleri and a more restricted L. vulgaris. The Carpathian newt L. montandoni was confirmed as a closely related sister species. This collective of six species forms the Lissotriton vulgaris species complex. Here we 1) delineate the distribution ranges, 2) provide a distribution database, and 3) produce distribution maps for all species. This allows us to 4) highlight regions where more research is needed to determine the position of contact zones.
