IMMUNOLOGICAL DATA ON THE TAXONOMY OF SOME ITALIAN LIZARDS (REPTILIA LACERTIDAE)

SUMMARY Immunological reactions tested according to Libby's photronreflectometric technique show that: (i) Podarcis wagleriana Gistel, 1868 and P. filfolensis (Bedriaga, 1876), two allopatric and morphologically very similar lizards of the Sicilian-Maltese Pelagian area, are full though very closely related species; (ii) Podarcis muralis marcuccii (Lanza, 1956), a strongly differentiated microinsular form of Wall-Lizard from Tuscany, actually belongs to the species muralis; (iii) the percentage of common antigens is still remarkable between the Lacertidae, Teiidae and Iguanidae. It is confirmed that Podarcis muralis (Laurenti, 1768) and P. sicula (Rafinesque, 1810) are full species.
