Abstract

The conspecificity of the Chilean Liolaeminae lizards Liolaemus isabelae Navarro & Nunez, 1993 and Liolaemus nigroventrolateralis Ortiz, 1994 is discussed. A careful comparison of the holotype and paratypes of L. nigroventrolateralis with the type series and additional topotype specimens of L. isabelae indicate the conspecificity of the two forms. Furthermore, the characters studied by Ortiz (1994) to diagnose L. nigroventrolateris do not distinguish this species from L. isabelae. There are no distributional or ecological differences between the two species. Therefore, we consider that L. nigroventrolateralis is a synonym of L. isabelae.
