Resumen

The differences and similarities of lizard assemblages can be explaned by historical or ecological factors or by the interaction of both. To examine these hypothesis we selected three communities with similar environmental influences in the Sierra Grande de Córdoba (Argentina). The sites selected where: Villa Las Rosas (31°56', 65°03'), dep. San Javier on the west side of the Sierra, Tanti (310,22, 64°36') dep. Punilla on the east side of the Sierra and Achiras (33°10', 64°59') dep. Rio Cuarto on the southem extreme of the Sierra. All these sites have more than eight species of lizards. The diversity of each site is described and the novelties, sustitutions and absences for each locality are discussed and compared with three external communities. A phylogenetic hypothesis of the species involved in this study is need to resolve the biogeographic problems.
