Abstract

An allozyme survey revealed instances of natural hybridization between Podarcis sicula and P. tiliguerta from a locality of southern Sardinia. Pure specimens of both species together with some F1 hybrids were found, but no evidence of backcrossing was detected. The hybrid specimens appeared morphologically intermediate between the parent species. The absence of backcrossed individuals indicate that free interbreeding between the two species is unlikely. Hybrids were found in areas of habitat disturbance only.
