Donoso- Barros (1970) described Liolaemus emrnae on thebasis of a single female from Totoralejos, on the saline flats of northern Cordoba Province, Argentina. The species was compared with Liolaemus chacoensis Shreve (1948) described from Fortin Guachalla, Paraguayan Chaco, from which it was presumed to differ by dorsal scales larger than ventrals, anterior border of ear opening denticulated, and dorsal pattern formed by a vertebral row of V-shaped spots. Subsequently (Cei, 1973) two additional specimens [from Buta Ranquil, Neuquen, Argentina [IBA-UNC.(Instituto Biología Animal, Universidad Nacional de Cuyo, Mendoza, Argen- tina)716] and Nacuñan, Mendoza, Argentina (IBA-UNC.808)] were referred to this species. However, these have now been determined to be anomalous individuals of Liolaemus darwini (Bell).Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Museo
