Abstract: Genetic variation in 12 populations of the Italian endemic spectacled salamander Salamandrina terdigitata was investigated through the analysis of 29 allozyme loci. Two well-differentiated population groups were identified, one ranging from the Tusco-Emilian Apennine to southern Latium, the other comprising populations from central Campania to Calabria. Nine diagnostic and four highly differentiated loci led to an average genetic distance of DNei=0.47 between the two groups, while within them DNei ranged from 0.00 to 0.05. The observed genetic structure strongly suggests that two distinct species have so far been included within Salamandrina terdigitata. The names Salamandrina perspicillata (Savi, 1821) and S. terdigitata (Bonnaterre, 1789) are here proposed for the species from central and southern Italy respectively.
