To our knowledge, there are no studies of mother-offspring recognition in Liolaemus lizards,even though many species have a refined discrimination capacity based on chemical signals,and some of them are viviparous with a close relationship between mothers and offspring. Westudied the reciprocal chemical mother-offspring recognition in the viviparous species Liolaemuszullyae, evaluating whether both mothers and offspring can discriminate between theirconsanguineous relative from another who is not genetically related. Six females gave birth inthe laboratory. Once the offspring were born, crossover experiments were carried out. The resultssuggest that mothers showed no clear evidence of discrimination of their own and other´snewborns. In contrast, newborns rubbed their faces for longer when scents were from otherfemales than from their own mothers, suggesting that newborns may recognize their mothers.We discuss the asymmetric mother-offspring recognition detected in this study.
