Resumen:
We describe a new species within the genus Liolaemus from southeast Argentine Patagonia. This new taxon, Liolaemus yatel sp. nov., presents anatomical traits shared with the L. lineomaculatus section within the L. lineomaculatus group, especially the absence of precloacal pores in both sexes. However, Liolaemus yatel sp. nov. does not exhibit any trifid dorsal scales, which is another diagnostic character of the L. lineomaculatus group. Moreover, this new species differs from other species of the L. lineomaculatus group in that dorsal and nuchal scales either completely lack keels and mucrons or are only slightly keeled. We also report, for the first time, the presence of trifid scales in Liolaemus magellanicus, another species included in the L. lineomaculatus section but constituting an independent lineage regarding the L. lineomaculatus group. The phenotypic traits of L. yatel sp. nov. and the presence of trifid scales in L. magellanicus challenge the study of phylogenetic relationships among the species of the L. lineomaculatus section, especially the establishment of its diagnostic characters.
