Testudinidae An overview of the chelonian species of Sardinia is presented, especially of the northern part of the island. Emys orbicularis and Testudo hermanni are considered to be autochthonous, T. graeca and T. marginata to be introduced. In addition to E. orbicularis, a second freshwater turtle (genus Mauremys) is known from the Upper Pleistocene. Sardinian pond turtles belong to a medium sized to small subspecies (Emys orbicularis capolongoi) with a shell length normally below 13,5 cm. The Sardinian subspecies is closely related to E. o. lanzai (Corsica) and E. o. galloitalica (southern France, western Italian peninsula) and forms with both a megasubspecies (galloitalica). E. o. capolongoi occurs in similar habitats as E. o. galloitalica, including clear, stony or gravelly brooks and rivers as well as standing waters with plant cover. Recently, Sardinian Testudo marginata have been described as an own subspecies (Testudo marginata sarda MAYER, 1992) in a tortoise fancier"s guide, an available name overlooked from »scientific herpetology« till now. Despite clear morphological differences compared with Greek T. marginata, the Sardinian population cannot be regarded as a valid subspecies. The peculiarities of adult Sardinian marginated tortoises are persisting juvenile characters, resulting most probably from a founder or gene drift effect. Different opinions on the date of the introduction of T. marginata are reviewed. In fact, it is unknown. The oldest literature record is from the end of the 19th Century. However, a much earlier introduction is sure. In Sardinia, T. marginata is mainly restricted to the Northeast of the island. There, it is a dweller of poor mountain meadows.
