Resumen:
The genus Liolaemus includes lizards whose distribution, endemic to South America, ranges from the cordilleras of Perú to Tierra del Fuego, from the Pacific Ocean coast to the Atlantic Ocean. The genus Liolaemus has more than 160 species described (Etheridge, 1995). Only 53 species (33%) have the karyotype defined, almost all performed with direct methods and Giemsa conventional stain. Cytogenetic analysis was performed for three male individuals of L. uspallatensis from Uspallata. The 33 metaphases of L. uspallatensis analyzed had a diploid number 2n= 28, with six pairs of macrochromosomes and sixteen microchromosomes. The chromosome number 2n= 28 has not been reported for the genus Liolaemus, whose diploid numbers range from 2n= 44 to 2n= 30 (Paull et al., 1976; Lamborot, 1993), extended to 2n= 28 with L. uspallatensis.
