Abstract In his recent self-published book "Reptiles en Chile", Diego Demangel Miranda presented 13 taxonomic changes for liolaemid and tropidurid lizards. While these could be considered validly published according to the International Code of Zoological Nomenclature, we show that these taxonomic propositions lack the necessary scientific rigor in...

The presence of precloacal pores is frequently used to differentiate Liolaemus males from females. Currently, this character is confusing in Liolaemus jamesi because it has been described the presence and absence in females. Here it was confirmed that L. jamesi males and females have precloacal pores.
