“…Liolaemus has been split into two subgenera, Liolaemus (sensu stricto) and Eulaemus, supported by both morphology (Etheridge, 1995;Laurent, 1985) and molecular evidence (Espinoza et al, 2004;Schulte et al, 2000), with each subgenus split into several groups (e.g. Avila et al, 2020). The L. elongatus group belongs to the subgenus Liolaemus (sensu stricto) (Morando et al, 2003) and comprises medium to large Liolaemus (with maximum snout vent length of approximately 100 millimeters), with long tail (approximately 1.5 of the SVL), absent or reduced sexual dichromatism, both presence of lateral dark stripe and light dots on the dorsum in almost all species, viviparous, insectivorous, mainly saxicolous, and in almost all species high amount of midbody, ventral and dorsal scales (Abdala et al, 2010;Avila et al, 2015;Troncoso-Palacios et al, 2018).…”

Resumen.- Los lagartos Liolaemus habitan en el sur de Sudamérica, siendo uno de los géneros de vertebrados terrestres más diversos del mundo. Dentro de este género, las especies del grupo de L. elongatus habitan en la cordillera andina de Chile y de Argentina, y en los afloramientos rocosos de la Patagonia Argentina. Aquí, nosotros revisamos la identidad taxonómica de una población de los Andes de la Región de O`Higgins, Chile, previamente confundida con L. cristiani. Nosotros encontramos que este taxón no es asignable a ninguno de los Liolaemus actualmente descrito y proveemos una descripción para este. Preliminarmente nosotros incluimos a esta nueva especie en el grupo de L. elongatus, siendo una de las especies del grupo distribuidas más al norte.

Evolutionary processes behind lineage divergence often involve multidimensional differentiation. However, in the context of recent divergences, the signals exhibited by each dimension may not converge. In such scenarios, incomplete lineage sorting, gene flow, and scarce phenotypic differentiation are pervasive. Here, we integrated genomic (RAD loci of 90 individuals), phenotypic (linear and geometric traits of 823 and 411 individuals, respectively), spatial, and climatic data to reconstruct the evolutionary history of a speciation continuum of liolaemid lizards (Liolaemus kingii group). Specifically, we (i) inferred the population structure of the group and contrasted it with the phenotypic variability; (ii) assessed the role of post-divergence gene flow in shaping phylogeographic and phenotypic patterns; and (iii) explored eco-geographic drivers of diversification across time and space. We inferred eight genomic clusters exhibiting leaky genetic borders coincident with geographic transitions. We also found evidence of post-divergence gene flow resulting in transgressive phenotypic evolution in one species. Predicted ancestral niches unveiled suitable areas in southern and eastern Patagonia during glacial and interglacial periods. Our study underscores integrating different data and model-based approaches to determine the underlying causes of diversification, a challenge faced in the study of recently diverged groups. We also highlight Liolaemus as a model system for phylogeographic and broader evolutionary studies.

We describe Liolaemus attenboroughi sp. nov., a lizard distributed in the northwestern Patagonian Steppe of Chubut province (Argentina) previously confused with L. kingii (Bell 1843). Recent studies based on molecular evidence supports its evolutionary independence. Here we provide a morphological diagnosis of this lineage, comparisons between three molecular species delimitation methods, and an updated phylogeny of the L. kingii group. Based on current knowledge of its distribution, this new species is allopatric with geographically close species of the L. kingii group.
