Abstract
Ocellated lizards from Tunisia and Spain respectivelywere hybridized. The hybrids proved to be much more aggressive than normal specimens but did not show any sexual activity among each other. Back crossing experiments revealed a strongly reduced fertility of the hybrids and demonstrated that the degree of genetic incompatibility by far exceeds the subspecific, i. e. infraspecific level. The two forms are, thus, ranked here as allospecies: Lacerta pater LATASTE, 1880, and Lacerta lepida DAUDIN, 1802. Ocellated lizards from Tunisia and Spain respectivelywere hybridized.
