Abstract
The Italian endemic genus Salamandrina was recently determined to be polytypic since two species, Salamandrina perspicillata and S. terdigitata, were recognized using both mitochondrial and nuclear genetic markers. However, data on their range is very scanty and no morphological traits are available to distinguish between these two taxa. A thorough field survey was carried out to detect and to sample new sites in areas in which Salamandrina remained unrecorded and to sample populations expected to occur in the documented range. Specimens were analyzed for variation of three mitochondrial DNA partial sequences of 12S and 16S ribosomal RNAs and cytochrome b genes. Attribution of individuals to either of the two species was therefore made on the basis of their haplotypes. Here we provide relevant information on the distribution of the two species, which were also found in areas where Salamandrina had previously been unrecorded, i.e. in the eastern Basilicata, in the region of Apulia and within the wide area which separated the two species. In the latter zone, a small area of sympatry between the two species was found. Furthermore, we analyzed the dorsal coloration pattern and size-related characters of the two species using Classification and Regression Tree analysis (CART), the results of which provided the first account of the morphological differences between Salamandrina perspicillata and S. terdigitata. The southern species, S. terdigitata, is smaller in size than S. perspicillata and differs in its coloration, mainly due to the red color on the dorsal surface of its tail.
