[Studies of Acanthodactyla in Tunisia. II. Biometrical relations]

The four species of the g. Acanthodactylus Wieg., 1834 occuring in Tunisia are quite individualized by their biometrical relations which, moreover, allow to bring out their relationships. The size of the upper quarter in our sampling oppose two groups of two species each one. The distribution of the ratio between the length of the body and that of the tail place apart A. boskianus from the three other species in a more marked way for adults of both sexes than for juveniles.
