Abstract: Speleomantes ambrosii and S. strinatii are morphologically similar but genetically well differentiated plethodontids inhabiting north-western Italy. Ten morphological characters were used to assess the amount of intraspecific sexual dimorphism in both species. On average adult females were 10% and 7% longer than males in S. ambrosii and S. strinatii respectively. ANCOVA showed that in both species there were no differences in body proportions between males and females of equal size. Multivariate analyses of size-adjusted morphological characters showed that species differed significantly in body shape, while sexes within species did not show significant overall body shape differences. The observed pattern of sexual size and shape dimorphism was similar in both species of Speleomantes and is discussed in relation to the reproductive biology of plethodontids.
