I upload this because zootierliste says that Jerez keep both Mauremys leprosa and Mauremys caspica. Jerez never kept Mauremys caspica actually. But once, M. leprosa was considered as a subspecies of M. caspica. So the signage is outdated and still labelled as caspica, but by the common names and distribution it's clear that they reference to M. leprosa.
